My AllStays Camp&RV shows a spot labeled as Little Coyote Dispersed at 40.3186667, -105.4888245, 4122-4592 Little Valley Drive Estes Park. A satellite view shows some open areas with at least one fire pit. It also shows as 20’max RV length and 4WD sometimes necessary. That would be due to the sharp curves needed to get there off the main road. But there are houses before the dispersed area, so it might be worth a call to the USFS office to get more information. There are also some USFS campgrounds, but expect crowds since RNMP is incredibly popular, particularly on the Estes Park side. Jackie’s comment about west side camping would probably be a more conservative choice.
