About these ratings

These jaw-dropping rock walls flanking Green Mountain have become the symbol of the city, with many Boulder businesses sporting their image as a logo. Flatirons One through Five are the most prominent, but there are also several smaller formations — with more creative names — to explore. Altogether, these picturesque slopes are the most popular rock climbing areas around (you can even see markings left by some of the first climbers, dating back to the 1940s, on Number Three). But for those of you who aren't quite comfortable entrusting your life to a harness, you can still take in the Flatirons from one of the area's hiking trails. For information about Flatiron trails, visit the City of Boulder website.

Overlooking Boulder from the city's southwestern edge (near Chautauqua Park), the Flatirons are free to visit every day from sunrise to sunset. Previous visitors say that no trip to Boulder would be complete without spending time admiring the rocks. But if you plan on hiking, travelers recommend coming prepared: The trails can be steep in places, not to mention slippery. "This is the must do hike of Boulder," said one TripAdvisor user. "You should bring some water and good footwear although we saw plenty of folks in sneakers and some brave souls jogging."
