We recently camped at Twin Lakes June 23-25th. The sites were a decent size and the Campground only had one other group. The sites were very nice, included a picnic table and firepit, my favorite feature though was PRIVACY, each site was surrounded by trees to separate you from possible neighbors.
Cell reception is spotty, no electric or showers, THIS IS RUSTIC, which is exactly what we wanted. There were the outhouses (Vaults) and a handpump for water.
It has stairs leading down to a small dock on the lake. There were plenty of Loons that made noise around midnight every night but other then that it was pretty quite.
