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.

We went in mid July 2016. Great super easy, shady walk. We took Edna (English bulldog) and she had great time playing in shallow creek along the path.

It's probably better to go earlier in the season. It was pretty much dried up when we went this weekend. No waterfall, but it was fun to climb the rocks.

Fun hike through the woods. I went in the Spring and the water was raging. Enjoyable ridge walking when you reach the fall. The road up to the trail head is pretty steep, so take caution.

Good hike for some shade. Falls are low right at this point.

Excellent afternoon hike. Well maintained trail. This late in the year the stream was at a trickle so the waterfall was not there. Still a nice time.

The trail is relatively easy and has some pretty cool views, isn't marked the best in some places but the view at the end is worth it all.

Beautiful short hike along a small stream... wasn't too busy, even on a Sunday.

Beautiful shaded hike that I would rate as easy. Lovely scenery: streams, waterfall, rocks, and wildflowers. I went early afternoon on a Saturday in June and it was pretty crowded. Trail is well defined and easy to follow.

For a hike for the dogs it was wonderful! The smoke from the fires got to a few of my group members so it shortly became a shorter hike. Careful on the rocks! Someone before us slipped and hit their head! Shady about half the time. Can't get into the water, would have loved for our dogs to get in.

Nice trail. I actually lost the trail coming back, but that's my fault for not paying attention. Only downside was you're not supposed to have any body contact with the water (Denver drinking water). I'd have loved to jump in for a swim on a hot day!

Nice and shady. There was some rock scrambling toward the end which tired me out for the return trip but I'm on the heavier side (390 lbs). FYI, google maps takes you past the trailhead; there's a parking lot at the intersection of CR 68 and FDR 359. The trailhead can be accessed from there.

Perfectly shaded, and easy trail for dog and kids. Contains a single challenging spot at the end, but very manageable.
