Comfort matters to your crew. No showers, no potable water on-site, and reviewers flag the bathrooms as inconsistently clean. Uneven sites and low-hanging branches also cause headaches for bigger tents or canopies.

Summer delivers the best conditions, with daytime highs typically in the mid-70s to low-80s °F and cool nights in the 50s–60s °F. Long daylight hours, warm water temperatures, and park naturalist programs peak during this season. Wind and mist can roll in off the lake unexpectedly, affecting beach conditions. Weekends and holidays fill quickly, so midweek arrivals offer quieter campsites and easier beach access.
Summer called the best season: warm days, long daylight and active water use.
