From Eve

Know before you go

Hi, I'm Eve. Here are a few practical things to know before exploring First Flatiron.

Arrive early, especially on weekends and during the summer, to secure parking at Chautauqua Park or along Baseline Road.
Bring plenty of water and sun protection, as the trails can be exposed, especially during the initial ascent.
Wear sturdy hiking shoes with good traction, as the trails can be rocky and steep in sections.
Consider bringing spikes or traction devices during winter months, as the trails can become icy and snow-packed.
Stay on marked trails to avoid erosion and protect the delicate ecosystem.
