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. Please note: 4 wheel drive vehicles recommended for accessing trailhead.

Really lovely! The end is definitely a little more difficult to see which way the trail goes, but with the roses blooming, you won’t really care!

Awesome beginner's trail with scenic views. Highly recommend!

It is a nice trial; shaded, terrain varying but easy, short & sweet. The waterfall leaves a lot to be desired. After the waterfall the trail is not well marked. It appears you must scale rocks to get a decent view of reservoir. On another note, the drive up from Boulder is exhilarating!

The end is just kinda scaling rocks, the trail ends. But if you are comfortable doing that you'll be rewarded with a beautiful large lake :)

Great Family hike! Loved that the trails down to the base of the waterfall and around the waterline of the lake were challenging but not so much that my 6yr old daughter couldn’t keep up. Shady most of the way- great way to spend a Monday afternoon!

Hiked this in the evening (5/9) and it was beautiful! The waterfall was flowing pretty nicely, and it was a very quick and easy hike.

Great short hike. We could not find where the trail led down to the base of the falls so we only saw it from above.

Nice little hike- a bit crowded but Saturday afternoon that’s to be expected!

Nice and shady. Easy hike along the creek to the waterfall. Must hike up and over the boulders to see the waterfall well.

Moderately Easy hike with a 2 year old. Shaded almost the entire way.

Fantastic trail for families. Short, 1mi in, 1mi out. Shaded, runs a long a creek which leads to a reservoir. There are signs stating not to get into the water though.

This was a really fun mellow trail that led to a scenic view of the lake. Very easy for all ability levels and extremely dog friendly. The trail wasn't too crowded which was nice especially since it is pretty close to Boulder. Once you get off the main road you have to drive on a dirt road for a few miles to access the trailhead. The dirt road was a lot of fun to drive on. I read some reviews saying that you need all wheel drive to get up there, I don't think its an accurate statement. It isn't any kind of strenuous driving and any car can make it up there. Just be aware of your surroundings because on the drive back from the parking lot I got a 2 inch screw in my tire on the dirt road. But all said and done it was a great hike with some really cool scenery. Two very big thumbs up, enjoy!

5/23/18: Great shady hike that begins with little switchbacks through an aspen grove descending into the canyon. There are 1-2 very short but steep steps over rocks. From there, it's a shady walk in the woods running along a creek until you get to a little point off Gross Reservoir. I continued on a trail to the left side of the reservoir, but it isn't too maintained--not sure if it's a real trail. Great for families with children, dogs (water!), and hot days.

Follow the trail up to the left and over the rocks to get to the bottom of the waterfall. Pretty hike. Easy. My friends 3 year old hiked most of it on his own.

This was a easy trail to do with children until the trail ended by the waterfall. We weren’t sure which way to go but was able to follow a path up and over. My 2.5 year old needed assistance climbing up but with help we got to the other side and even made it to the reservoir as well. Very pretty, short, and easy.

Great quick hike! The waterfall was little but very pretty. And the reservoir was absolutely beautiful! Shady in spots but mostly sunny. Also there was no snow and only a few muddy areas on the trail! Got a little confused right before the waterfall (where it gets rocky) but luckily some fellow hikers were there to show us where to climb up. Will definitely be back!

It was a short hike but great for what it is. My dog loved it! The water ran next to the entire trail which ended at a small but nice waterfall. Didn’t feel like climbing down the rocks to the reservoir.

Super fun! Can be really rocky in some places and to get to the water fall you gotta do some climbing. Totally worth it. Perfect for summer or winter, definitely one of my favorites. Not to much snow on the trail right now, no microspikes needed.

Great for kids. Our 3 kids (2, 4, 6 yoa) walked whole way there with no trouble, if you’re patient with little ones. Once got to top of falls had to supervise more. Extra 5 min walk to reservoir was very scenic. Will come back.

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.
