Learn more about alerts →Cabin campers get the most here: ADA-accessible, full kitchens, patio wildlife views, and separation from the tent loop. Spring weekends are the sweet spot for fishing the newly restocked bass population and catching migrating songbirds at dawn.
Tent campers who need level ground will be disappointed. The sites cluster together, slope noticeably, and privacy is thin. Swimmers should also know the lake has had repeated water-quality advisories in recent years.

Spring is the best window for camping here. April temperatures climb from the mid-40s to mid-60s, rising into the 60s and 70s by May. Bass spawn in late spring, making the lake productive for anglers. Wildflowers and migrating songbirds peak during this stretch, and trails stay cool enough for comfortable hiking. Crowds thin compared to summer, though weekends fill up as locals shake off winter. Summer gets hot and busy. Winter quiets the place down entirely, with occasional cross-country skiing when snow cooperates.
Described as the best window: pleasant temps, bass spawn makes fishing productive in spring.
