3 Best Day Trips From Denver | Condé Nast Traveler

"The classic Sanitas 3.2-mile loop uses Mount Sanitas Trail to ascend, East Ridge Trail to descend, and the Sanitas Valley Trail to cool down. It's popular with hikers, runners, and dog walkers, and its likely that an ultra-fit Boulder local or two will pass you on the climb. The moderately steep ascent up to Sanitas Mountain features high steps on logs and boulders, but shade offers a bit of respite. Don't let the false summits fool you, when you get to the top you'll know it: All of Boulder is spread out to the east and you'll also see views of the foothills and Indian Peaks mountains to the west. A more technical section—the East Ridge Trail—makes for a tricky down, but the trail eventually spreads out on an easy gravel road with great views of the red-hued Flatirons." - Megan Barber

I haven't been hiking in a while so this trail was rigorous but so fun. It took my body a few days to recover! Coming down around the bend was a lot of fun. Beautiful views of Boulder at the top.

First time in Colorado and was recommended this hike by my partners cousin who said it was easy. Well as someone from Arizona who is not use to elevation this hike definitely feels like medium to medium hard!! You have to climb. A LOT! "Hated it" going up but thats because I'm dramatic. I thought it was really beautiful and worth it if in fun company. We took a lot of breaks and it took 3 of us about 5 hours to go up and down the loop. I look forward to see if it gets easier the next time we visit.

We have no experience in hiking, and the mountain part of the loop was doable, but quite tough. But it was worth it for beautiful views and the experience. Definitely need to have water! The only thing that we didn't like was that in many places the trail is not marked (and is not obvious), so we had to wait until someone was coming to figure out the directions. Luckily this is a very popular trail.

Great hike! Make sure to where appropriate shoes on this trail. There are a lot of rocks that you can slip on as you make your descent. The views are pretty and you get a great quad workout.

Popular hike for a reason. It's got great views, really cool terrain, and a challenging uphill workout. You need to be fairly fit. If you do this hike regularly, you will become very fit!

It is a nice place for you to have several choices:to try harder trail,you can take the mount sanitas mountain trail, easier to chose the valley trail loop. T

Challenging at first but the way down was much easier and peaceful. It was worth it in the end. Beautiful scenery.
