The 33-mile circuit of Crater Lake is one of the most popular road-bike trips in the state. Although it would seem at first that this would be an easy trip, numerous ups and downs (especially on the east side of the lake) turn it into a demanding ride. Keep in mind that there are more hills on the east side, but there are also more views. An alternative is to do the 21-mile out and back ride from the Rim Village to the Cleetwood Cove Trailhead (and maybe add on a boat tour of the lake). There are no bike rentals available in Crater Lake National Park.

Crater Lake may be a dramatic draw for out-of-staters, but Oregonians visit neighboring Diamond Lake five times as often. A paved 11.5-mile loop trail provides an easy ride around the lake for mountain bikers. Distance: 11.5-mile loop, with 100 feet elevation gain.

Mountain Biking

Many of the local trails are great for mountain biking, including both Union Creek Trail and Union Creek Spur Trail, both of which are accessible from the Union Creek Resort grounds. The U.S. Forest Service recently installed a brand new bridge for ATVs, motorcycles, and mountain bikes that leads the way to dozens of branching paths.

The Lost Creek Reservoir Loop is 22 miles of easy-to-intermediate riding. Located just 17 miles from Union Creek Resort, the trail travels around the entire lake and includes both single track and paved areas. It will take between 2.5 and 3.5 hours to make the entire trip, and you’ll enjoy great views of the lake throughout.
