Maxwell falls, about 50 minutes from Denver, is a GORGEOUS hike. I went in February, with my boyfriend and my dog. It was snow filled and slippery, slippery to the point of dangerous at some points, but it was worth every minute. The website for the hike does say it’s only accessible March-November, so to be safe you should probably stick to those months. My boyfriend and I can’t wait to go back this summer to see it again, thawed.
We started at the Maxwell Falls upper trail, which was beautiful, and mostly flat. Very easy. It’s only half a mile until you reach the falls, which were frozen when we found them. We decided to continue on the Maxwall Falls (lower) trail until we reached the far end of the Cliff Loop, and then took the Cliff loop back to Maxwell Falls (upper) and then back to our car.
The Cliff Loop was MUCH more difficult. It was very steep both up and down, and longer than we had expected, but once your reach the top of the cliff, it is definitely a sight worth seeing and I highly recommend it if your legs are up for the challenge.
