This is a hike-in campground down a 3.5 mile trail. It sees heavy use from locals on the weekend. There was plenty of room during the week when I was there. Lena Lake is quiet and serene and the perfect place to sit on a log and journal. Other people walked around the edge of the lake but care must be taken as it's a bit rugged. Follow the leave no trace principles and this place will be one to return to again for yourself and others.
