This is one of the best birding places on Earth! There are many side trails that lead to smaller ponds and dense vegetation. Today we saw Cedar Waxwings, Bullock’s Oriole, American White Pelican, Redwing Blackbirds, Eastern Kingbirds, Canada Geese and several unidentified species. We also saw a rabbit. The trail also offers incredible views of the front range.

Like the rest I accidentally traveled this instead of Santais.. it's a nice trail honestly to walk or run on. There is a little pond at the end. Some wildflowers growing.

Towards the top there is a lot of rock scrambles. If you're not use to this either wear proper shoes or bring poles to hold your grip. I saw a few people slide while going down. Take your time. This is sorta steep. Take the Mount trail then go down the valley trail.

So beautiful! Awesome mountain views with lots of wildflowers.

I would do this again. Beautiful!
Some scrambling, not a beginning hike.
A great moderate hike.

Wow! This was very difficult. I had to scrabble over some Boulders. I was not expecting that. Bring poles, to save your body on gong down on either side.

Plan early, as I can get extremely hot. I ran out of water, had to borrow friends. I brought 2L.

Lots of gnats at the top which was annoying.

Beautiful ever changing landscape.
I think this is my first 'difficult' trail completedl.

360 view at the top. If you are not in good shape you should reconsider; the climb is pretty steep and steady once you get off Mesa Trail. If you take Shadow Canyon trail up make sure you stay right when you hit the rocky area that you feel like you have potentially lost the trail. Great view though, def worth it.

I love this trail so much. It is an exceptionally easy walk along the river that the entire family can enjoy. We always bring the dogs and find little pools in the river to play in and relax.

Good place for a nice stroll in the evening or after work.

Awesome hike! It is not easy tho

Great views from the top. Flat most of the way and then a steep incline to the top of Green Mountain. Easy to navigate and not that hard with a few water breaks.

View at the top was better than I was expecting. Great hike - the climb to the top is a little strenuous but the rocks/steps are very easy to navigate

I read a few reviews that said this was a great beginner trail and I disagree. This trail, on both sides of the mountain, has a lot of climbing and scrambling on rocks and I'm glad I wore decent hiking boots. The trail was a bit crowded in parts and definitely a workout but some of the views were nice.

Beautiful hike! Continued on Mesa trail instead of going the shadow canyon route. The hike is easy up until about the last three quarters of a mile in which the ascension to the top is pretty tough. The flies at the peak are fairly annoying but they don't bite.

Well marked trail. Not sure why this is rated difficult; it’s a good hike but the only challenging part was the amount of snow still here. Ended up here due to a road closure, no summit but a very secluded & quiet trail.

Beautiful views and all the wildflowers!

Definitely a beautiful easy trail. More like a walk in the park.

This trail is truly amazing. Conquered it with a cat and a dog. I came from Denver so I parked at the Crescent City parking lot to save 20 minutes and not have to drive through Boulder. I’m not a very fit person and I was able to accomplish this trail, with a few breaks every so often lol. I also took the trail clockwise, for a bit of a challenge. I saw lots of chipmunks! You have 360 views nearly the entire hike. The trail conditions are good, there are a few steep parts where the sand/pebbles are really slippery so wear shoes with good traction or bring a pole. I didn’t have any falls but my buddy slipped a couple times. Definitely worth the drive! Perfect for a day hike.

Pretty good hike overall. Flat and then incline to the top of Green.

My favorite cardio trail. But very populated.

Great little hike to introduce my puppy to hiking. It is short and not very challenging, with wonderful views. Several benches around the trail to stop and enjoy the scenery. Part of the trail is close to the road so you do hear the occasional car.

Great trail with some steady inclines. Nothing too crazy but defiantly a good workout. Plus some of the views are amazing!

Hiked with the doggo on 5/22/18 - started at about 9:15 and was at the summit by 9:50 including taking a couple viewpoint breaks, didn’t see anyone going up but started to get busy on the way down. Some small uphill bursts throughout and then gets decently steep at the very end - definitely had me panting and grumbling to myself but then the view is awesome at the top. My dog (80lb) had a blast. Lots of shade, VERY green after all the rain, no ice, and pretty wildflowers! Beautiful way to spend a morning.

Great hike, Kylie, Oakley and I enjoyed the afternoon.

Awesome hike with the pup!

Great hike for the dogs- lots of shady spots and beautiful views.

Cute hike! Last bit gets your heart pumping. Love the view of Boulder.

Hiked on 5/20. It was a cloudy day so we didn’t get any views, but it was still fun! The trail was muddy but passable. Not a fly in sight. Met lots and lots of friendly puppers!
