Best Time to Camp at Oso Group
Experience the dramatic seasonal transformations of mountain life at Oso, where crisp, dry winters invite cozy campfire gatherings under star-filled skies. As summer arrives, the campground basks in perfectly moderate temperatures that make outdoor adventures irresistible. Spring and fall bring their own magic, with occasional rain showers nurturing the forest and rare dustings of snow that transform the landscape into a winter wonderland during transitional periods.
Peak season Apr–Sep with boating, hiking, biking and stocked fishing; busiest and most active time.
Open into early fall (through Sep 20) with good scenery, but late-fall access is closed.
Opens Apr 18; late spring offers good hiking and cooler mountain conditions but limited early-spring access.
Campground closed out of season; no winter bookings available.
