Best season: summer. Summer is the best time to use Boulder Group Camp because warm, stable weather (typically daytime highs in the mid-60s to upper-70s °F and cool nights in the 40s–50s) makes lake activities, hiking, and group gatherings reliably pleasant. Boating, swimming, fishing, and long daylight hours are at their peak, and the forest is fully green with wildflower remnants in early summer. Expect heavier crowds on holiday weekends and summer Saturdays, so plan midweek visits for more solitude; note that by, Peak months: July, August, June, September Avoid: October, November, December, January
Summer cited as best: cool days (mid-60s to upper-70s), shade, and peak lake activity season.
