Mt. Sanitas is a 3.3 mile moderate loop trail in Boulder, CO. The trail head begins at Mapleton Avenue. This is a very popular trail and one of the very first trails we completed after moving to Denver. We’ve done this hike when the trail is snow covered and in the spring/summer when it’s clear. You really can’t go wrong with this hike if you’re visiting the Boulder area, just remember to bring your hiking chains if you decide to try it in the fall/winter! There is a 1348 feet elevation gain, so make sure to take breaks and bring lots of water. The trail does have a series of log and rock steps that lead to the peak, however the views of the city and the Front Range are definitely worth it! If you’re hoping to bring your furry four legged friend, you’re in luck! Dogs are allowed on this trail. The trail head is approximately at 45 minute drive from Denver. I suggest getting an early start to avoid the heat and crowds on the weekends. Enjoy some pictures from the trail!
