Worth it?
Is Diamond Craters Outstanding Natural Area worth it?
Diamond Craters is one of the American West's least-visited volcanic showcases, packing an almost absurd variety of basaltic features into 17,000 acres of high desert Oregon.
Craters, cinder cones, lava tubes, a water-filled maar, and driblet spires all coexist within a compact, driveable loop. Free entry and genuine geological rarity make it a serious find. The experience score of 58 reflects limited infrastructure, not limited interest. If raw volcanic terrain and interpretive self-discovery appeal to you, this place punches well above its profile.
Who it is for
Geology enthusiasts, photographers chasing otherworldly desert landscapes, and campers who prefer solitude over amenities will love this. Families wanting developed facilities or visitors expecting maintained trails and visitor-center amenities should look elsewhere.
Worth seeing
A single accessible area containing craters, cinder cones, lava tubes, spatter cones, and a water-filled maar, representing the full spectrum of basaltic volcanism
Free entry into a genuinely remote and uncrowded high desert landscape
Interpretive programs that give volcanic context most self-guided visitors would otherwise miss
Photography opportunities across surreal, textured lava formations with minimal human infrastructure in frame
Our tipThe loop road is the primary way to experience the craters, so check road conditions before visiting as high-clearance vehicles handle the rougher sections more comfortably. Pair this with an interpretive program if one is scheduled, since the geological variety here rewards context more than almost any other site in Oregon.
How we scored it
Why Diamond Craters Outstanding Natural Area scores 58
The Experience Score is one transparent formula, run the same way on every unit and computed only from public records: how much a unit documents and how easily you can reach it. It is a breadth-and-access index, not a rating of scenery or crowds. Each input below is weighted and capped so no single factor can dominate. Here is what fed Diamond Craters Outstanding Natural Area's 58 of 100:

The honest limits
What the score cannot tell you
The Experience Score measures what a unit documents and how reachable it is. It does not try to measure what our data cannot see: scenery and beauty, how crowded a place gets, trail or road conditions, the weather the week you visit, or the quality of a particular ranger program. A small, focused site can score lower than a sprawling park and still be the better trip for you. Read the score as a like-for-like comparison of what each unit offers on paper, and read the verdict above for who it actually suits.

Scenes from Diamond Craters Outstanding Natural Area
Diamond Craters Outstanding Natural Area at a glance
From the NPS: Diamond Craters, an Outstanding Natural Area of 17,000 acres (23 square miles), has some of the most diverse basaltic volcanic features in the nation clustered within a small, accessible area. The area displays an entire range of eruptions possible in basaltic volcanism. It was formed sometime in the past 25,000 years and now resembles a thin, rocky pancake with a few bumps. Features identifiable at the Outstanding Natural Area include craters and vents, cinder cones, spatter cones, lava tubes, driblet spires, a graben, and a water-filled maar. Know Before You Go It took thousands of years of volcanic activity to form Diamond Craters, but only a few seconds can damage its features. Help BLM protect this area. Please do not destroy or collect plants, animals or rocks. There are no restroom facilities or other amenities. Bring your own water and shelter and follow Leave No Trace principles: pack it in, pack it out. Keep your vehicle on hard-packed road surfaces and obvious parking areas. Point of Interest Located in southeast Oregon's high desert country, Diamond Craters is really unlike any other place in North America.
On documented breadth and access, Diamond Craters Outstanding Natural Area ranks 31st of 37 park and public-land units we score in Oregon.
