Lake Constantine sits about 4 miles off of Tigiwon Rd outside of the town of Minturn. These camp spots are only accessible by hiking in. The lake can get fairly busy on weekends in the summer but the weekdays are usually quiet. We spent a night up there in early July and saw 1 other person on a Monday night. The hike to the lake was fairly easy, takes about 2 hours each way and climbs roughly 1300 ft. Upon leaving the parking lot you MUST fill out the overnight camping sheet and attach a tag to yourself. This is your permit for the night and it is free.
Spots are laid out along the edge of the lake on either side and are not numbered or marked. This is a first come, first served area. The spot we found was to the left side of the lake right off of the trail and had enough room for a couple tents. Coincidentally, this is the same spot where many of our friends have camped as well. I would say this is one of the better areas. There was a pre made rock fire ring that sat against a rock to reflect heat back (we went during Colorado's 2018 summer long fire ban), so we could not take advantage of this and had no fire this weekend.
The lake itself is very large and offers some amazing high alpine fishing. We caught many trout while fly fishing throughout the day and night.Dry flies worked very well at dusk. Because of the lake and the creek, the mosquitoes in this area are bad. BRING BUG SPRAY!
Remember, this area is only accessible by backpacking in and there are no camping amenities. Lake Constantine sits in US Forest Service land so you must obey all forest service rules and closures when in place. Overall, amazing spot. Great for a night getaway or for someones first backpacking trip.
