Boulder, Colorado Map

A nice hike for me. Lots of Ponderosa Pine and boulders. Wild Turkey were plentiful and there was only one other couple on the trail. Will definitely do again.

Pretty difficult considering the snow, mud, slush, and ice. However, totally worth it when you get to the top! I will be returning when the trail is dry.

One of the better service road hikes I have done. Easy hike with great views. Road continues well past my turnaround spot if you want more miles. Late April snow made the road a bit muddy, but it was fine with boots on. Long, steady uphill the entire way back, but less than 200ft per mile, so it is still an easy return.

Late April snow made the road muddy, but it was no issue with a pair of boots. It is a long steady uphill the entire way back, but less than 200ft per mile incline, so it is still easy.

Enjoyed a morning out.... busy place but good for avoiding too much solitude

I love how close to Boulder it is! Great views and a good workout

Great trail some rock climbing beautiful views at top.

Love this hike! Beautiful mountain and creek views. Challenging, but awesome if you are looking for a long hike. Well maintained and not crowded.

Great hike, a little harder then we were thinking. Brought two labs along, they got muddy but the Arch gave a nice view and a great place to sit and eat a little snack. The hike it self was out and back, the way there being mostly up hill. I thought it was "moderate" but definitely some slippery rocks this time of year. Wish i had worn my hiking boots, no my old tennis shoes.

Hiked on 4/22/18. Started around 930am and took us two hours with a nice stop at the top. The trail had very little snow/ice but a lot of slush which made it slick at times. Spikes not needed. It was moderately trafficked but it felt like mainly with trail runners. Absolutely beautiful views from the top.

Awesome trail. Great for when other trails are wet. This one seems to stay dry when others are not. Quick 7 ish mile ride. Takes under 1.5 hours on a mountain bike. Some challenging spots when climbing. Amazing downhills. Beautiful scenery.

Very steep and a bit slippery on the way down. Very busy but it was Earth Day afterall! Good views!

Started this hike a little after 10 am on a Sunday (4/22) and there was hardly anyone on the trail - mostly runners, probably due to the gradual slope and smooth packed gravel trail with relatively few larger rocks to navigate. Sanitas had gotten a bunch of snow/rain the day before but the trails were totally dry; no mud at all. I chose this as an easier alternative for out of town guests to the more crowded Mount Sanitas/Sanitas Valley loop and was glad I did so. A better workout this is not, but the views are pretty and the trail is quiet!

Probably great for kids or the elderly. Accidentally went on this instead of Sanitas. You basically travel along the highway.

One of the most beautiful trails I’ve been on yet. 7.5 miles is very doable even for the most reluctant rookie hiker. Trials are in good shape and there are very few muddy spots. Active trial for hikers and bikers alike.

Beautiful day to be on the trail! I started in the afternoon and encountered moderate foot traffic. Gorgeous views and friendly trail mates!

It has a little bit of everything. I look forward to going back.

Started out OK, but there were a lot of dogs off leash and they really stressed my support dog, Sierra, out. I admit I was pretty high, so I'm not sure how she lost her support animal vest. But it really messed up the reset of the hike, The cops came as well because some of some hassle between a biker and a nude runner. They just bummed me out, bad vibes from the very start.
Oh I also lost my keys. So big buzzkill on the west side of the trail.

My out of shape friend from Texas did it and so can you. We had copious amounts of cured meats beforehand! And a banana cream pie.

Gorgeous hike. Can be heavy traffic on the weekend but still not bad. The view is worth the hike.

Beautiful day on the trail. Even though this is ranked moderate it’s a tough one. The views from the arch are incredible.

Awesome hike! The climb was a fun challenge. Be ready for a crowd.

Many trails shown in the map are closed which makes me detour around for more than one mile. In general a good but tiring trail.

Easy trail. Such a beautiful park. Sunny and cool today.

Great day for a hike. Beautiful park. A bit too crowded for me. I got here early so parking was not an issue but there are not a lot of spots to park.

Great trail! Has a beautiful view of the flatirons and a creek running along the entire trail for your dogs to cool off on a hot day. They have trash stations through out the trail so you’re not carrying poop bags for too long. Very dog friendly!! My only complaint is that this parking lot is pretty small and space fills up quick. I go in the middle of the day through the week. If there’s no space there’s always dry creek trail a few minutes up the road!

Boring and too much traffic. Accidentally went here instead of Sanitas and was highly disappointed. Don't waste your time.

Great hike, although a little crowded on the weekends.

Great trail within minutes of Boulder. Steady climb to the top of Mt. Sanitas, seemed to be less crowded than the other routes to the summit.
