Aschoff Buttes is located within the Bull Run Watershed Management Unit (BRWMU) and is restricted to the general public by federal law. Locked gates are at all road entry locations. Authorized access is required to enter. The BRWMU is patrolled by Portland Water Bureau security personnel. Electronic surveillance is used to keep an eye on things.
The City of Portland offers guided tours June through October. Unfortunately, none of the tours include any of the SOTA summits.
