Heaton Bay

Great campsite with abundant trees. The bike paths were excellent.
The massive infestation of mosquitoes made the experience near intolerable. Mosquitoes bit and swarmed us despite multiple head to toe applications of DEET.

Was able to book one night on short notice. Lovely site on Dillon Reservoir.

Loved our spot right on the reservoir. It was clean, quiet, and secluded. Camp host was very friendly. We will definitely be back!

Beautiful trees surrounding us. Some sites on water, ours wasn't. Could only get one night reservation a couple weeks out, so moved from Lowry to here and back to Lowry to get 3 nights. Had good internet and phone with T-Mobile.

Great campground. Access to so many activities. Lots of mosquitoes but that’s camping

A fantastic campground with great water views and easy access to the town of Frisco.

The wildflowers were in bloom, and the trees are growing--but generally from a few feet tall to a few inches thick trunks, so not yet providing a lot of shade. Unfortunately this year mid-July the mosquitos were plentiful and hungry. We have had and were having some wet weather, and I don't know how much the nearby wetlands restoration also contributes. My lower rating is just an honest assessment of how this one experience was affected by the mosquitos :-).
We got spotty cell service with t-mobile, especially for data. The sites are paved slabs, mostly level, with a picnic table, a fire grate, and a large bear box for storing food. Most sites did not have an improved location for a tent or canopy. The newer loops had hookups, and we were not in these loops. There are pit toilets (and dumpsters) dispersed through the campground, and a location in loop B for water including a pull through with both a threaded and an unthreaded tap. There is a dump station (for $10 currently) at the other end of Frisco next to a regional wastewater plant. Next to the dump station are two potable water taps as well.
Heaton Bay is convenient to Frisco, and the bike path around the lake crosses the entrance road, so we found it convenient to bike directly from the campground around the lake, to Breckenridge, and to Vail Pass.
While the campground was labeled as full, every night there was one or more empty spaces, but we had to book three separate spaces for four nights in order to have reserved spots, and did not try to stay Friday night, even though it was obvious that people had not shown up for their reservations. A lot of campground hosts do not move quickly to release spots when people don't show up.
