Laws & Policies

Sandboarding Girl
When done in accordance with policy, sandboarding is an example of a fun and safe activity that does not harm the dunes, wildlife, wilderness character, or natural quiet of the park.

NPS/Patrick Myers

"The fundamental purpose of parks and to conserve the scenery and the natural and historic objects and the wild life therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations."

- from the National Park Service Organic Act of 1916

The National Park Service has a dual mission: to conserve scenic, natural and cultural resources to leave them "unimpaired" for future generations, while providing for the enjoyment of people today. These two often seem to be in conflict, but the bottom line is that the NPS is responsible to provide for the enjoyment of parks, while never allowing that enjoyment to impair resources or the safety and enjoyment of other visitors. Futher, the dunefield and most of the Sangre de Cristo Mountains are federally designated wilderness areas. The policies below are made in accordance with the NPS Organic Act and Wilderness Act.

Marijuana on Federal Lands

With the legalization of marijuana in the State of Colorado, Great Sand Dunes National Park and Preserve would like to provide clarification regarding the use of possession of marijuana on federal lands. The recently passed Colorado State law, which allows for limited recreational marijuana use under certain conditions, has no bearing on federal laws which continue to identify marijuana as a Schedule I illegal drug, and prohibit its use.

Possession of marijuana or use of any amount of marijuana is still prohibited in Great Sand Dunes National Park and Preserve, its facilities and campgrounds. Violations are punishable by a fine of not more than $5,000.00 for an individual or $10,000.00 for an organization, or imprisonment for not more than six months, or both (16 U.S.C. 551, 18 U.S.C. 3559 and 3571).

If you have questions, please contact the Chief Ranger's Office by email or call 719-378-6322.
