The Umatilla National Forest, located in the Blue Mountains of southeast Washington and northeast Oregon, covers 1.4 million acres of diverse landscapes and plant communities. The Forest has some mountainous terrain, but most of the Forest consists of v-shaped valleys separated by narrow ridges or plateaus.
The landscape also includes heavily timbered slopes, grassland ridges and benches, and bold basalt outcroppings. Elevations range from 1,600 to 8,000 feet above sea level. Changes in weather are common, but summers are generally warm and dry with cool evenings. Cold, snowy winters and mild temperatures during spring and fall can be expected. More about the Forest...
Forest Conditions: Know before you go!
The forest conditions can change dramatically without warning. It is advisable to consult your local ranger district office before your trip.
SNOW ALERT! Winter is a great time to enjoy and recreate on your national forest! Whether you ski, snowmobile, sled or snowshoe always be prepared for changing winter weather conditions. Many forest roads on the Umatilla National Forest will close December 1 through April 30; consult our motorized recreation use maps for more information. The condition of forest roads that remain open during the winter and early spring can change dramatically without warning; wind, snow and rain events can have substantial effects on road and trail conditions causing hazards and obstructions to travel. Please contact your local office before your trip. Here are a few tips for safe winter recreation.
