The St. Martins Sea Caves, located in the village of St. Martins, New Brunswick, are a captivating testament to the power of nature and the incredible tidal range of the Bay of Fundy. Carved over thousands of years by the relentless action of the tides against the soft sandstone cliffs, these caves offer a unique opportunity to explore the ocean floor and witness the dramatic effects of coastal erosion.

The ocean floor is exposed, revealing the entrances to the sea caves, beckoning visitors to explore their depths. The cave walls display shades of red, with water dripping down, creating a visually stunning spectacle. Exploring the caves at low tide allows you to walk along the beach and venture inside these natural formations. Be mindful of the tide, as it changes quickly, and plan your visit to allow ample time for exploration before the water returns. The area is also a haven for birdwatchers and rockhounds, adding another layer of interest to this coastal destination. The village of St. Martins itself is a charming seaside community with a rich shipbuilding history. The harbor is encircled by two covered bridges and a lighthouse, making it a picturesque spot to visit.
