Maxwell natural area is a great hike that is in fort collins.
To simply go up to A and back to parking lot is roughly around 4 miles round trip. The first 2/3 of a mile or so is relatively flat and then it starts inclining. However it still only has around 600 feet or so of elevation gain so really is not very strenuous.
You can see people hiking, trail jogging or mountain biking.
The trail is somewhat narrow once you get rolling and get into the switchbacks, so be prepared for that.
This is a great go-to trail if you dont have a lot of time but want to get out. In spring/,summer be careful this area frequently does have a lot of rattlesnakes. read more
