Explore San Carlos in Costa Rica for Arenal Volcano, rainforest trails, hot springs, wildlife, dairy country and the northern plains.

San Carlos is Costa Rica’s largest canton, occupying a broad sweep of northern Alajuela Province between the Central Volcanic Range and the lowland frontier near Nicaragua. Its principal urban centre is Ciudad Quesada, while La Fortuna, at the foot of Arenal Volcano, is the best-known international arrival point. The canton covers a remarkably varied landscape: hot springs and volcanic foothills around La Fortuna, dairy country and pasture near Quesada, forested mountains towards the Cordillera de Tilarán, and humid northern plains crossed by rivers and wetlands.
Read more about San Carlos
La Fortuna provides the region’s most developed visitor base. From the town, roads lead towards Arenal Volcano National Park, lava fields, rainforest trails, waterfalls and bathing facilities fed by geothermally heated water. Arenal’s near-perfect volcanic cone dominates many views, although its summit and upper slopes are protected and access is restricted. The surrounding forest supports howler monkeys, toucans, sloths, frogs and numerous other species, making guided walks and wildlife-focused excursions central to the local experience.
Further north and west, San Carlos becomes less resort-oriented. Ciudad Quesada is a practical commercial centre with museums, cafés, markets and services, and is a useful base for understanding the canton’s agricultural economy. The mountain roads towards the Juan Castro Blanco National Park pass through dairy country and cool, rain-soaked uplands, where cloud forest, springs and watersheds are more prominent than volcanic scenery. Smaller communities reveal a rural landscape shaped by cattle, dairy production, sugar cane, pineapple and other crops.
San Carlos’s history is closely connected with migration, road building and agricultural colonisation. Settlers gradually opened routes from the central highlands into the northern plains, while rivers and fertile volcanic soils supported expanding farms. Today, the region combines working countryside with one of Costa Rica’s most established nature-tourism areas. Visitors can move from urban markets and farm-based food experiences to rainforest trails, canyoning routes, horseback excursions and quieter mountain communities within the same canton.
The best itineraries allow for the distances involved. La Fortuna and Ciudad Quesada are separate bases rather than interchangeable neighbourhoods, and mountain or rural journeys can take considerably longer than the map suggests. San Carlos rewards travellers who balance Arenal’s headline landscapes with the canton’s agricultural identity, forest reserves and everyday northern Costa Rican life.

Getting to and around San Carlos

How to get there

Most international visitors reach San Carlos by travelling overland from San José and the Central Valley. La Fortuna is commonly accessed by road from the capital, while Ciudad Quesada is reached through routes connecting the northern plains with the Central Valley. The nearest major international gateway is Juan Santamaría International Airport near Alajuela, outside San Carlos; it is normally followed by a road journey. Costa Rica’s domestic flights may serve the La Fortuna area, but routes and operating arrangements can change, so confirm current availability before relying on air travel. Long-distance buses connect major towns, although a private transfer or rental car can be more convenient for rural itineraries.

Transportation

La Fortuna has the greatest concentration of visitor transport, including taxis, tours and transfers to trails, hot springs and adventure sites. Ciudad Quesada is a regional transport hub with local buses serving surrounding communities. A rental car is useful for combining La Fortuna, Ciudad Quesada and mountain districts, but roads become narrower and slower away from the main routes, with occasional potholes, steep sections and limited lighting. Guided transfers are practical for visitors who do not wish to drive. Walking works well within central La Fortuna and Ciudad Quesada, while rural attractions generally require a vehicle, taxi, organised excursion or advance transport planning.

Best attractions in San Carlos

San Carlos offers a broad range of attractions, from highly organised nature tourism around La Fortuna to quieter forest and agricultural experiences elsewhere in the canton. Arenal Volcano National Park provides trails through rainforest and volcanic terrain, with views towards lava fields and the volcano when weather permits. Around La Fortuna, visitors can also find waterfalls, hanging-bridge walks, horseback routes, wildlife excursions, river activities and geothermal bathing facilities. These experiences vary considerably in intensity, from accessible forest paths to guided canyoning and more demanding outdoor adventures. In the uplands north of Ciudad Quesada, Juan Castro Blanco National Park protects wet mountain forest, springs and important watersheds, although access requires more planning and is less resort-oriented. The city itself is useful for markets, local services and a glimpse of San Carlos’s dairy and agricultural economy. Throughout the canton, farms, gardens and rural viewpoints provide a different perspective on the region, where cattle, sugar cane and tropical crops share space with forest corridors. Visitors should distinguish between activities inside protected areas and private commercial properties, checking access, weather and current conditions before setting out.

Best landmarks in San Carlos

Arenal Volcano is San Carlos’s defining natural landmark, rising above the forests and settlements around La Fortuna as a near-symmetrical volcanic cone. Its form is associated with the 1968 eruption and the lava landscapes now protected within Arenal Volcano National Park, although cloud frequently obscures the summit. The park’s forested slopes and lava fields provide a visible reminder that the area remains a volcanic environment rather than simply a tropical resort. La Fortuna Waterfall is another prominent natural feature, where water drops through rainforest below a viewpoint and swimming area managed within a protected setting; access involves a steep route and local rules. In the northern mountains, the forests and watershed landscapes of Juan Castro Blanco National Park are significant landmarks of a quieter kind, representing San Carlos’s high, wet interior rather than its tourist centre. Ciudad Quesada’s urban form and public spaces reflect the canton’s role as a regional agricultural and commercial capital. Together, these places show the contrast between volcanic foothills, mountain forest and working town that defines San Carlos.

Best restaurants in San Carlos

Dining in San Carlos reflects the meeting of Costa Rica’s everyday home cooking, agricultural production and an international tourism scene concentrated around La Fortuna. Casados, rice-and-beans combinations, plantains, soups, grilled meats and fresh fruit are widely available, while cafés and bakeries in Ciudad Quesada and La Fortuna serve practical breakfasts and snacks. The canton’s dairy economy is particularly visible in milk, cheese, cream and other farm products, and roadside or market-based businesses may offer locally made foods alongside tropical produce. Around La Fortuna, restaurants range from simple sodas, the name commonly used in Costa Rica for informal eateries, to establishments catering for visitors with vegetarian, international and contemporary menus. Rural inns and farm-based venues can provide a closer connection with local ingredients, but opening arrangements vary. Coffee is part of the national food culture, even though San Carlos is better known locally for pasture, dairy and tropical agriculture than for being a principal coffee-growing region. Prices and choice are generally greater in tourist centres than in outlying communities.

Best bars in San Carlos

San Carlos has an evening culture rather than a region-wide club scene. In La Fortuna, the largest concentration of nightlife is around the town centre, where visitors find casual bars, restaurants, hotel lounges and places offering music after the day’s outdoor activities. Some venues cater to international travellers, while local establishments provide a more everyday setting for residents and visitors from elsewhere in Costa Rica. Ciudad Quesada has bars, cafés and restaurants serving as social meeting places, but its nightlife is more closely tied to local commerce than to tourism. In smaller communities, evenings generally centre on family-run restaurants, neighbourhood bars or occasional live music rather than late-night dancing. Hot-spring resorts and larger hotels may offer relaxed evening facilities without functioning as nightlife districts. Check current arrangements locally, and use registered taxis or pre-arranged transport when returning from rural accommodation, where roads may be dark and services sparse.

Best shops in San Carlos

Shopping in San Carlos is divided between visitor-oriented purchases in La Fortuna and everyday commerce in Ciudad Quesada and the surrounding market communities. La Fortuna offers shops selling Costa Rican coffee, chocolate, locally produced foods, clothing, artwork, jewellery, wood items and practical outdoor equipment, although product quality and provenance vary. Look for clear information about where food and crafts were produced rather than assuming that every souvenir is regional. Ciudad Quesada has a broader local retail range, including supermarkets, bakeries, clothing shops, household businesses and markets serving residents and farmers from across the canton. Dairy products, tropical fruit, sauces and packaged agricultural goods can make useful, easy-to-carry purchases, subject to airline and customs rules. Small rural shops are more likely to have limited stock and cash requirements. Gifts should respect Costa Rica’s wildlife-protection laws: do not buy products made from protected animals, plants or archaeological material. Independent galleries and craft outlets around the tourism corridor provide more distinctive alternatives to mass-produced souvenirs.

San Carlos essentials

Currency and Payment
San Carlos uses Costa Rica’s national currency, the Costa Rican colón (CRC). Cards and contactless payments are widely accepted in hotels, established restaurants, supermarkets, tour offices and many attractions in La Fortuna and Ciudad Quesada. Carry some colones for small cafés, rural businesses, local transport, roadside stalls and places where connectivity is unreliable. United States dollars may be accepted in parts of the tourism industry, but paying in colones usually makes prices and change clearer. Notify your bank before travelling and keep a backup payment method, particularly when visiting remote mountain areas.
Safety
Use ordinary urban precautions in busy commercial areas and avoid displaying valuables unnecessarily. Around Arenal, remain on marked trails and never enter restricted volcanic zones or approach rivers and waterfalls beyond signed viewpoints. Heavy rain can make paths slippery and rivers rise quickly, while heat and humidity increase the need for water, sun protection and insect protection. If driving, allow for slow traffic, livestock, pedestrians, motorcycles and poorly lit rural roads; avoid unfamiliar mountain routes after dark. Choose established guides and operators for rafting, canyoning, climbing or similar activities, and check that equipment and weather procedures are explained.
Emergency Situations
Costa Rica’s national emergency number is 9-1-1, which connects callers with the appropriate police, fire, ambulance and other emergency services. Give the name of the canton, town, lodge or attraction and describe the nearest access road, as rural locations can be difficult to identify. Follow instructions from the National System of Conservation Areas and park staff around Arenal Volcano and other protected lands. For outdoor activities, provide an itinerary to your accommodation and use a reputable guide, since mobile coverage can be inconsistent in forests and mountain districts. Travel insurance with medical and evacuation cover is sensible for adventure-based trips.
Do's and Don'ts
Respect marked trails, private land, wildlife and local communities, and take all rubbish with you when visiting forests, rivers and viewpoints. Do not feed monkeys, birds or other wildlife, and do not cross barriers around volcanic or geothermal areas. Ask permission before photographing people, farms or private buildings. Costa Rican public etiquette generally values courtesy, patient queueing and modest behaviour, while service charges and tipping practices can vary by establishment; check the bill rather than assuming. In rural communities, dress practically and respectfully, especially away from resort facilities, and avoid treating working farms or Indigenous cultural contexts as photo props.
Local Tips
La Fortuna is busiest around the main attractions, so early starts can make popular trails and viewpoints more comfortable. Ciudad Quesada offers a more everyday view of San Carlos, with services, food businesses and access to the surrounding agricultural districts. The canton is large, and Juan Castro Blanco National Park is not a quick add-on to a La Fortuna day trip; plan it as a separate excursion with current access information. Ask accommodation staff about road conditions before heading into the mountains, and keep flexible plans during the wet season when thunderstorms may affect outdoor activities.

History of San Carlos

Indigenous Northern Lowlands Before Colonisation

Long before the modern canton existed, northern Costa Rica was inhabited and used by Indigenous peoples whose territories and trading networks extended across the plains and foothills. The region’s rivers, forests and fertile soils supported hunting, fishing, cultivation and movement between the central highlands and the northern frontier. Indigenous communities, including peoples associated with the wider Maleku cultural area, remain part of the historical context of northern Alajuela, although San Carlos should not be presented as culturally uniform or as exclusively Indigenous territory. Archaeological evidence across northern Costa Rica points to settlement and exchange before Spanish colonial expansion.

A Colonial Frontier Beyond the Main Settlements

During the Spanish colonial period, the deep valleys and wet lowlands of present-day San Carlos remained distant from the principal settlements of the Central Valley. Difficult terrain, rivers and forest limited permanent colonial penetration, while the northern frontier was connected more readily to Indigenous territories and scattered routes than to major urban centres. Spanish influence expanded gradually through religious, administrative and agricultural networks, but San Carlos did not develop as a dense colonial landscape of grand churches and central plazas. This relative distance helped preserve extensive forests and kept the area on the margins of Costa Rica’s early export economy.

Settlement Routes and the Founding of Ciudad Quesada

Modern settlement accelerated in the nineteenth and early twentieth centuries as migrants from the Central Valley and other parts of Costa Rica moved into the northern plains. La Unión, the settlement that became Ciudad Quesada, was established in the late nineteenth century as routes were opened through difficult terrain. The town was renamed Ciudad Quesada in 1911, the same year San Carlos was created as a canton. Roads, bridges and river crossings gradually connected the area with the central highlands, allowing farms and trading settlements to expand.

Agriculture, Cattle and the Northern Frontier Economy

Throughout the twentieth century, San Carlos was transformed by agricultural development. Cattle ranching, dairy farming, sugar cane and later commercial crops became major parts of the local economy, supported by fertile volcanic soils and a warm, humid climate. Cooperative dairy production helped give the canton an enduring agricultural identity, while improvements in roads and markets encouraged closer links with the rest of Costa Rica. Forest clearance brought economic opportunity but also environmental costs, contributing to later efforts to protect watersheds, wildlife habitat and mountain ecosystems.

Arenal’s 1968 Eruption and a Changed Landscape

The eruption of Arenal Volcano in July 1968 was one of the defining modern events in the history of the La Fortuna area. Previously regarded as dormant, the volcano produced explosions, lava flows and ash that affected nearby communities and permanently altered the surrounding landscape. The event caused fatalities and extensive damage in settlements close to the volcano, while also creating new lava fields and attracting scientific interest. Over subsequent decades, volcanic scenery, hot springs and rainforest became the foundation of a major nature-tourism economy around La Fortuna, alongside agriculture and other local livelihoods.

Protected Forests and Nature Tourism

Late twentieth-century conservation policy changed the relationship between San Carlos’s forests and its economy. Arenal Volcano National Park protects major areas of volcanic forest and lava terrain near La Fortuna, while Juan Castro Blanco National Park safeguards high-elevation forest and important watersheds in the canton’s northern mountains. Nature tourism expanded alongside these protected areas, bringing guided walks, wildlife viewing, hot-spring facilities and outdoor adventure businesses. The result is a region where conservation, farming and tourism coexist, sometimes uneasily, and where water, land use and visitor pressure remain important contemporary concerns.
