This was a stunning campground tucked away high up in the mountains on Independence pass. You take the turn to Lincoln Creek Campground, and instead of going into that campground, you drive 6 miles on a dirt road to get to Portal Campground. During your drive on the dirt road you will pass free dispersed campsites that are more secluded compared to a campground feel. Portal Campground is on a resevoir (very cold as its at about 10,000 feet).
From Aspen, Colorado travel eleven miles southeast on Highway 82 toward Independence Pass to Lincoln Creek Road. Turn right and travel seven miles south on Lincoln Creek Road.
CAUTION: high clearance vehicles recommended for Lincoln Creek Road.
WARNING: No vehicles over 35 feet long are allowed on Highway 82 to access this campground.
There are two vault toilets at this campground. You can camp literally feet away from the water if you get a good spot. Be aware of the weether moving in here as its at a high elevation. Also be aware of food storage etc. with wildlife.
All in all, this is a great campground that is somewhat hidden and well worth the travel. Bring the paddle boards!
