Carter Lake Bouldering

It is about a 45 minute drive from Boulder. From Boulder, take CO 119 (Diagonal Highway) north into Longmont until it terminates at 287. Go north on CO Hwy 287 approximately 11 miles, where the road takes a blatantly obvious, 90 degree, banked, arcing, right turn, with a gas station on the west side of the road. There are signs at this point for Carter Lake. Instead of entering the turn, go straight ahead, and then take a left on 56 (the road right behind the gas station). Follow for about 3.1 miles, and then take a left. Follow for another 3 miles, and enter the park. You have to pay for a day pass here. Follow the road to a junction with a sign that notes that continuation goes to the south side of the reservoir, and to take a right means to go to the boat launch.

Going straight, the road arcs up and right 200 yards further, and the lake is basically in sight. There is a pull-off for a dirt parking lot on the right side, but it kind of comes as a surprise. Park here and take the Fawn Hollow Trail north, staying on the ridge line or below, towards the lake.

Going right from that junction, you park and walk south to access the boulders around the lake.
