View from the summit of Green Mountain overlooking Colorado’s Continental Divide on a crystal-clear summer day.

Today’s Outdoor Picture of the Day captures one of Boulder’s most rewarding summit views: Green Mountain with the majestic Continental Divide stretching across the western horizon. From this rocky summit, the rugged peaks of the Indian Peaks Wilderness rise beyond Boulder’s foothills, creating one of the Front Range’s most unforgettable panoramas. It’s the kind of view that makes every step of the climb worthwhile.

At 8,144 feet, Green Mountain is one of Boulder’s signature skyline peaks and a favorite destination for hikers seeking a true summit experience close to town. Located within the City of Boulder’s Open Space and Mountain Parks (OSMP)system, the mountain offers spectacular scenery in every direction. To the east, Boulder, the plains, and the iconic Flatirons spread out below. To the west, the Continental Divide dominates the skyline with snow-capped peaks that often remain white well into summer.

Other Popular Routes
Hikers can also reach Green Mountain via Saddle Rock, E.M. Greenman Trail, and connecting trails through Chautauqua, each offering its own combination of forests, rock formations, and panoramic overlooks.

Before You Go

Many OSMP trailheads require paid parking for non-Boulder County registered vehicles, and parking areas often fill early on weekends. Arriving early or hiking on weekdays provides the best experience.

Bring plenty of water, wear sturdy hiking shoes, and start early during the summer months to avoid afternoon thunderstorms. If you’re hiking with your dog, be sure to check current OSMP Voice and Sight and leash regulations before heading out.

Whether you’re looking for a challenging workout, a peaceful escape above the city, or one of Boulder’s most spectacular mountain panoramas, Green Mountain delivers. From its rocky summit, the Continental Divide stretches across the horizon in a view that reminds you why Boulder remains one of Colorado’s premier outdoor destinations.
