Public Lands in Colorado and Mushroom Foraging

Trying to find a spot to forage in Colorado? The best place to start is typically public land.  Here is a rundown of public land options in Colorado from the viewpoint of a mushroom forager.

Local Parks

There are myriad local (city and county) parks across Colorado, but each are has its own local rules and must be researched on a case-by-case basis.  Some localities, the Boulder area for instance, have clear signage and firm rules against foraging and they are enforced.  Other towns may not have any rules!  Keep in mind you may want to avoid town parks impacted by dog feces, herbicides and pesticides.

Colorado State Parks

At the state level, it is illegal to forage in any and all state park unless clearly posted otherwise.  We are not personally aware of any state parks that have posted permission to forage; please comment below if you know of any state parks that permit foraging.

Federal Land

Most of the foraging opportunities in Colorado are on higher elevation land managed by federal agencies like the the BLM, USFS or National Parks.  The modern forager must navigate this patchwork of agencies and their rules.  Following is a breakdown of Federal Lands.

National Parks

Colorado has four national parks: Rocky Mountain National Park, Mesa Verde National Park, Great Sand Dunes National Park and Black Canyon of the Gunnison National Park.  It is forbidden to forage any products in Colorado’s National Parks. Don’t even think about it.


The Bureau of Land Management manages millions of acres in Colorado with mushroom hunting potential.  Personal picking is free and no permit is required.  Click here for a map.

USFS – National Forest

The United States Forest Service manages 11 national forests (and 2 grasslands).  Like all USFS land around the US, each respective forest creates its own foraging rules. Generally speaking in Colorado, personal foraging is allowed with a permit and commercial foraging is allowed in about half the forests. Again, generally speaking, Wilderness areas don’t forbid foraging but the leave no trace ethic frowns on harvesting mushrooms in these zones.  Click Here for a map.

Arapaho & Roosevelt

Permit Page


They have a link on their permit page where you can request a forest product permit. There are several ranger districts and the forest seems to push mushroom permits down to the ranger district method. 

Within this forest, only the Boulder Ranger District has published rules: The Permit is required for personal mushrooms.  $2 per lb, 20 lb max annually, no Wilderness collection.  Interestingly, they state mushrooms can be measured by volume, with 1 gallon = 1 lb.  The website says that Collectors must note their location the permit.

Medicine Bow-Routt

Medicine Bow-Routt National Forest & Thunder Basin National Grassland


Personal Permits are free: 1 Gallon per day/5 per year.  Commercial Permits  are $20.  This forest provides a map with areas for picking clearly marked – make sure to visit this page and check out the maps, it has its area divided into 10 zones. 

Wilderness areas are marked on the maps and are off limits. So are Research areas & Special Interest Areas.  

Matsutake must be cut in half!

White River

Personal permits are required and free and available at the local ranger district office. They have very little information their website, but we visited the ranger station and learned that commercial picking is forbidden. Wilderness picking is not addressed.

  • Boulder Ranger district measures mushrooms by volume, with 1 gallon = 1 lb
  • The Boulder Ranger District also says collectors must note their location the permit. On many permits: they want you to denote the date, location and lbs of mushooms, then write this info directly on the permit.
  • No online permits available, anywhere

Wilderness collection

Learn about wilderness areas in the “Special Areas” tab of each respective forest.  Some forests strictly forbid foraging in their Wilderness areas. Others don’t mention it one way or another.  One must assume that if it is not addressed in published regulations (they address many other items in their Wilderness rules), then it is allowed. However, the messaging was consistent across all National Forest administrative unites encouraging and practicing Leave No Trace principles while in the Wilderness.  The 4th (of 7) Leave No Trace principle is “Leave What You Find.”

With late spring snows it could shape up to be another great foraging season in Colorado this year. As always, let’s hope for at least average rains, that is all it takes!

Good luck out there!
