Avery Lake is a gorgeous, secluded, spring-fed lake in northern lower peninsula Michigan. The lake itself boasts some islands and a canal to explore. Loons and bald eagles are easy to spot. The campground is a bit rustic, but keeps this beautiful area natural and accessible to those who don't own cabins on its north side. There are never many campers here, which is a shame, but it remains one of the area's best kept secrets.
