Winter Camping at 300 Campground

300 Campground is the only area that is open in the winter time. If you have a trailer or motor home that’s small enough and you want to stay at 300 Campground in the winter, you’ll need to check the weather and come when road conditions are safe enough for you to drive on. If road conditions allow for it, you’ll need to pick a site that will provide you with electric hookups so that you can stay warm.

There will be no water hookups though, due to freezing temperatures. Flush toilets will also be unavailable, but there are vault toilets that you can use instead. Not many people like to come camping in the winter, but if you’re up for it, you won’t need to worry about making any reservations. If you can reach the site, it’s all yours for the taking.
