"The Jax in Broomfield will issue OHV permits. Other locations might also."
You can buy one anywhere that sells fishing and hunting licenses. Although the seller may not be familiar with the process.
"My belief
1) If it's a Forest Service "road" - no permit needed for my Colorado plated street vehicle
2) If it's some sort of "trail" - a permit _might_ (or not) be needed.
In my time here in Colorado, I rarely visit "trails" that I think need a permit and thus rarely buy a permit. When I do, I visit the local sporting goods store where they have the permits in stock (in/out in 10 minutes)."

"It seems the areas you need the sticker for are changing every year, and if I'm reading the description from Rainbow Falls correctly I think you might need a sticker to use any roads or trails that are on a MVUM, or just for what is considered an OHV trail, which for an OHV is anything on the map but for a plated vehicle it's just what is considered an OHV trail. wtf... I'm just buying the sticker and forgetting about it.

"Free Motor Vehicle Use Maps (MVUMs) are available at your local Forest Service Ranger District office. Please pick up a MVUM before you head out. These maps identify the Forest Service roads and designated motorized trails, that are open to Off-Highway Vehicle (OHV) use. All resident owned OHVs being operated on Forest Service system roads and trails, are required to have a valid Colorado OHV Registration. If the OHV is from another state, a Colorado OHV Use Permit is required. For motor vehicles with a valid state license plate being operating on designated OHV trails, a Colorado OHV Use Permit is also required.""

This is the best list I have seen that details which "trails" require the permit on plated vehicles.
