A small, scenic rustic campground. Grounds and facilities are well maintained, vault toilet buildings were clean through our entire stay. Water is available from a solar well; it tasted fine and appeared clear. All roads within and leading to the campground are paved.
The onsite host here for the 2021 season is a class act. You won't come across many people with his level of interest in each and every facet of infrastructure that goes into a national forest recreation site. He has a great love for the national forest and puts an incredible amount of care and energy into the two campgrounds he hosts. He's also advocating to get two nearby idled campgrounds - Mineral Lake and Lake 3 - reopened.
East Twin has one walk-in site that's both spacious and secluded from the rest of the campground. It has very nice lake frontage, as do most sites here.
All sites have ample spacing and vegetation between one another except site 8 and 9. Sites 7 through 9 would make a good spot for a group gathering if booked all at once.
East Twin Lake is swimmable. The bottom turns from sand to silt as you get a ways out from shore, but at that point the depth increases quickly enough that it's not an issue. Depending on the time of year and the wind speed or direction, you may encounter some algae suspended in the water that sticks to your skin. It's nothing that can't be washed off and this only happened to us on one of the multiple days we went into the water. The waterfront seemed most suitable for swimming at sites 7 through 10.
