Looking for a trail that will provide some shade on a hot Colorado day? This hiking trail has shade, plus a waterfall, a stream, a canyon, and lake. It’s hard to beat. Forsythe Canyon is just outside Boulder, Colorado (1hr 15min from Denver), and is an easy to moderate hike.

This is a great spot on a hot summer day. There is a Creek that runs along the trail. Bug spray is a necessity. Mosquitos are fierce on this trail! It's very confusing to find the waterfall and reservoir because the trail seems to just end and there are no signs. You have to look for a little trail that leads up and over rocks. You have to climb down to the falls or keep going to the reservoir. There is just a small access spot to the water and no swimming allowed. My dog ( Labrador) had some problems getting over the rocks to get up to the trail leading to the water. Not sure how that would be with kids.

The hike was good, but there was a part where it was difficult for my Jack Russell.. It was an enjoyable day!

Decent hike but there wasn't anything very special about it. Some rocky areas could make this hike challenging for some children and dogs.

This is an easy and serene hike. It runs along a brook and the sounds are relaxing. It is not well traveled and I probably would not do it alone due to seclusion and bear warnings. Only saw about 5 hikers and they were near the trailhead. It is a bit overgrown and there are a lot of mosquitoes so come prepared. If you're hoping to see a big waterfall, you will be disappointed. At the end it is very rocky and you have to climb over big rocks. I believe it was about 2.5 miles overall to get to the point where you see the lake. It is hard to get down to the lake so I wouldn't consider it an access point.

Fun out and back hike. Had the whole trail to ourselves. Saw one other person almost at the end on the way back. The waterfall is pretty small and you do have to climb down onto some rocks to see it. Easy enough of a hike for my 8-year-old who isn't into hiking. Take bug spray if you are sensitive to mosquitos. I didn't find them bad but my daughter was complaining about them in certain sections.

2 miles total in and out! The waterfall is hidden behind some fallen branches and it's little. There is a rocky spot you must climb... may not be so easy for all dogs. At the end of the hike you can see part of the reservoir, which was gorgeous! Clear waters!

This was a really great walk/hiking to the waterfall there were many shady areas in the trail that followed the creek so it wasn't excessively overheating you!
