One of our first stops when we got to Boulder Junction was to stop by the visitor center. Fishtrap Lake, at least where we were wasn’t very swimmer friendly, since it was more grassy water than sandy. We asked the lady working for suggestions on swimming and hiking and fishing. For swimming she suggested Lake Nichols, saying little to no one would be there. She was right. We took a short trip over, just to check it out and minus one resting biker there was no one around, and even he left relatively shortly after we arrived. There is an area to pump water (it takes awhile and seems like it doesn’t work, but it does), and a picnic area. I rolled up my jeans and tested out the water, the bottom of the lake had a muddy sandy consistency and probably would have been fun to swim in. It was very beautiful and peaceful.
