About
Welcome to the northern gateway into the Blue Mountains. Alder Thicket Campground is located just three miles into the Blues along Forest Service Road 40, accessible via a scenic drive from Pomeroy, Washington. The campground features overgrown trees and tall alder shrubbery that provide ample shade during hot summer days, creating habitat for grouse and white-tailed deer. This small, rustic campground operates on a first-come, first-served basis with no fees required. Basic amenities include vault toilets and picnic tables at each site, though campers must bring their own water as no potable water is available on-site. The campground's location makes it an ideal starting point for exploring the surrounding Umatilla National Forest, with hiking trails accessible within five miles and the historic Clearwater Guard Station just six miles away. During winter months, Forest Service Road 40 is closed for snowmobile use, and the campground serves as a rest stop for snowmobilers rather than a camping destination. The area offers a peaceful mountain camping experience for those seeking a quiet retreat in the Blue Mountains.
Directions
From Pomeroy, take 15th Street south for approximately 17 miles to the forest boundary. The paved road turns to gravel and becomes Forest Service Road 40. Continue on Road 40 for approximately 3 miles. Alder Thicket Campground will be on the right.
