SUNRIVER, OR -- The Lava River Cave opens for the season Friday. Through Memorial Day, the cave’s entrance gate will open at 9 a.m. and close at 4:15 p.m., Thursday through Monday each week. A valid recreation pass is required. Starting May 31, the cave will be open those same hours, seven days a week through September 15. US Forest Service officials say the gate will also close periodically, when the parking lot is full, to avoid overcrowding.
The Lava Lands Visitor Center also opens Friday and will follow the cave’s schedule of days open. Its hours are 9 a.m. to 5 p.m. During peak season, from June 17 through Labor Day weekend, a shuttle runs every 20 minutes between the Visitor Center and the summit of Lava Butte.
The Forest Service plans to open the Paulina Visitor Center in Newberry Caldera Memorial Day Weekend. Access to the caldera is from Paulina Peak Road, managed by Deschutes County. Check the road department's website for road opening information.
You'll find more information on all of the locations within the Newberry National Volcanic Site at the Deschutes National Forest website.
