First off, make sure you’re using the GPSing to Blue Lakes Trailhead, Telluride 81435 There are two different trailheads and there is camping at the other one (going through Ouray), but you can find that through the NPS system (Thistledown Campground and Angel Creek Campground).

The true dispersed camping is along the route to the “telluride/ Ridgway” trailhead. You should be entering the forest through route 7. This is an 8-ish mile road from the highway to the forest entrance. The camping spots will not appear until you’re actually across the forest threshold (there is a sign and a cattle guard), with only about 1.5 miles left your gps-ed route. The round is rough and long, but manageable in a 2wd car. (I have a Camry.)

I stayed here the past two nights and was lucky enough to have some campers split their space with me. We were right by the stream, maybe a half mile from the TH itself. It’s shortly after the meadow, on your left as you drive in. Cars definitely came and went throughout the evening, but the sound of the stream drowned them out. The temps are def dropping at night this time of year and it was in the 30s. There was ZERO cell service for Verizon. Would def stay here again - in warmer conditions!

You are also able to hike your gear in and camp at the Lower Blue Lake level itself, if that’s you’re thing!
