Natural Features
Visitors to the Umpqua National Forest are often taken aback by the unique landscapes of southwestern Oregon. High Cascades glaciation, whitewater rapids, and explosive geologic events have shaped the distinctive landscape on the 983,239 acres of forest that provides spectacular scenery as well as an abundance of natural and cultural resources.
Verdant stands of hemlock, fir and cedar transition to forests of mixed conifers and hardwoods at lower elevations, while alpine ecosystems dominate high peaks.
The translation of the word "Umpqua," meaning "thundering waters," defines the area. The Forest's waterways and diversity create desirable habitat for many species of fish and wildlife, in addition to providing outstanding recreational opportunities to our local communities and visitors.
Getting there
From Canyonville, OR, turn off of southeast Main Street onto southeast 3rd Street / OR-227. Continue on OR-227 for approximately 36 miles. The campground is on the left side of the road.
