The Greater Sand Dunes ACEC is part of the larger Killpecker
Sand Dunes. The western portion of the ACEC includes the Sand Dunes and
Buffalo Hump Wilderness Study Areas (WSA). These are areas of land that have
potential for inclusion in the National Wilderness Preservation System. The BLM
is required by law to maintain the natural character of WSAs. Recreational
activities like hiking, hunting, and horseback riding are allowed while those

Wilderness Study Areas (WSAs) to provide interim protection for this area until
Congress can make the final decision. BLM has determined that the Buffalo Hump

Please note: If you are trying to find these dunes for your
first time, I am not sure that I would recommend doing it in a motorhome or
with a large trailer. The dirt road is very long, and the condition of
the road changes with weather. Bring a GPS and use this information as a
tool, but don't depend on this page as your sole means of direction unless
you like an adventure.
Killpecker Camping Area:
Camping is allowed in the parking area. Pit toilets and running
water are available.

Greater Sand Dunes Area of Critical Environmental Concern
The Steamboat Mountain
area is crucial birthing habitat for deer and elk. This area is closed to
motor vehicles from May 1st through June 30th to protect this habitat.
The western portion of
the ACEC includes the Sand Dunes and Buffalo Hump Wilderness Study Areas (WSA).
These are areas of land that have potential for inclusion in the National
Wilderness Preservation System. No motor vehicle traffic is allowed in
The WSA has not been designated as Wilderness, but must be
"protected" by the BLM until Congress does something to either
designate or free it up. If access is important to you, please contact
your representatives in Congress and ask them to:
1. Release Buffalo Hump Wilderness Study Areas (WSA) back to
its' former use.
2. Enact a Wilderness Study Release bill so that WSA's are not left in limbo
