trail locations for Boulder, Colorado

great hike - lots of dogs- pretty easy with some good views.

Gorgeous hike, the view at the top is completely worth it.

loved it! the kids had fun stopping and playing by the creek. beautiful area.

Hard and Strenuous hike. Has you doubt yourself a few times but absolutely worth it in the end! I tracked it on my Garmin Fenix 2 and it counted 9.4 miles not 7.7, so a heads up there!

Awesome view under the Arch!

solid trail for a short hike with people visiting from lower elevations. Not too difficult if you're in good condition and take your time.

Had a great time hiking to the summit of Green Mountain, had plenty of motivation from fellow hikers, and dogs, to make it to the top. Needed a nap afterwards but worth it!

Great trail and the view is beautiful at the top. There is a steep rocky climb so bring good shoes and lots of water.

This trail is not open to reach the peak Monday through Friday, until further notice. There are crews working to replace bridges. Really excited to get back out there and make the trek. The lower trails before the closures are beautiful. Mallory Cave is an alternative hike from the same trail head that has views overlooking Boulder.

Great trail for a shorter hike with amazing views.

Very rocky with the trail hard to find at some points. Would recommend taking a left to start the loop.

Great trail for hiking with our dog. Trails are well marked. Mileage for loop overall elevation gain matched up fairly close to fitness tracker used.

Hard AF but great views and fresh air. Picnic areas as well. Great spot for lunch.
