One of my favorite trails in Boulder located in Chautauqua park. It's a little over 3 miles with…read moresome elevation, but I think it's relatively easy. My friend who was visiting from sea level who doesn't hike much was able to do it with no problems. It's a beautiful hike through tree line, nice vertical and stone steps and a unique arch at the top! There are big rocks to sit on and enjoy the stunning vistas and observe sweet chipmunks running about.

This is the kind of hiking trail that I'm not unhappy about having done once, but I really can't see myself coming back to repeat the experience.

I was only in the Denver area for a week, so wanted to keep it lowkey with the hikes and went to…read morethe Flatirons to do so instead. Given that the Flatirons essentially sit at the base of the Rocky Mountains, this is a much more doable area for those who are just visiting and haven't acclimated to the change in elevation! There are a ton of hiking trails that stretch for miles and can be explored all throughout the Flatirons, but the best part of the Boulder Flatirons is its proximity to the city of Boulder! Boulder literally sits at the foothills of the Flatirons, so its a quick jaunt from the mountains to the city in this area and the city of Boulder has a great downtown, college town, and just generally a ton to offer to tourists and locals alike! A must visit when you're in the Denver area!

We started by a nice entrance (great parking) just outside the Roosevelt National Park. Excellent place to bike, although we were on foot. We enjoyed our 3 mile hike.

Definitely would recommend getting out un the fresh Colorado air! We had perfect weather and enjoyed the creek!

The trail is well-maintained and marked. The trailhead sign isn't readily apparent from the road so we had to pull over and check that it was the right one. The GPS did have the trailhead as slightly further down the road but we ended up in the right place. There's parking along the road, FYI. The trail will take you to the top of Mount Sanitas. Take a look at the map I posted -- there are multiple trails that take you to the peak.

Beautiful hiking trail just outside of Boulder. I freaking love this trail. I was in Denver and…read moreBoulder for a conference & to see friends. This was one of the short hikes I was hoping to squeeze into my busy day so that I could get that amazing mountain view that I don't get to see in the city. The trail itself is not too steep, and offers beautiful views all around, no matter where you are on the trail. When you are navigating to the trail, you will be driving uphill, and lose cell signal as you approach the base. There isn't really any signal on the trail in general. Parking is all roadside parking at the curved bend of a road. There are clearly areas to park for hikers. This trail when I was hiking was populated by locals either hiking solo or in a small group. Would definitely recommend for a couple hour hike. Only took me about 2 hours.

I just don't need to be up that early these days. There is a display with information describing the parts of the view and since this is my little city, I know what is where. In some light and times of year you can easily see my street if you know where to look. The campus and downtown are easy to identify. Enjoy a ride up but know the gates to all viewing spaces on Flagstaff are now locked at night to prevent issues that might start a wild land fire that could sweep down into town.

This was an amazing trail near boulder! We decided instead of trekking the beginning we drove to…read morethe top of the mountain instead for the vantage points. It was high up (over 9000k ft) and I've never experienced elevation like that before so taking a few steps made me out of breath very quickly. The views were incredible though! Seeing the valley of Denver and the Rocky Mountains on the other side were breathtaking. There wasn't much snow for March as you could only see it on mountains that were much farther west and taller. It really gives you an idea of how high up the mountain is when you see people and trees look like the size of ants. The drive to the top was also wild with a twisty road that definitely felt like something that would be extremely difficult if it were icy out which thankfully it wasn't when we visited! Highly recommend checking out if you are in the boulder area.

It was quite fun, an easy stroll, but a bit windy at the top, though the views were nice on this sunny day. It can be very hot up there in the summer. Some of the forest around it burned in the big FourMile fire of Sept, 2010, but the tree cover for the hike itself is intact and the views still quite picturesque. There is convenient parking at the trailhead.
