WA Restrictiona

[Montana Mike]

Here’s my experience:

Some National Forest trails in Washington (about 2/3) allow Stock on the trail which includes horses, mules, llamas, and goats. All the trails that allow Stock, allow people, of course, and dogs.
 
Other trails are designated Hiker only, which means no Stock.   However, a few of the Hiker trails do allow llamas and goats.

Some areas (closer to Seattle) tend to have mostly Hike only trails, in some other areas most of the trails are open to Stock.

The NF website trail listings will usually tell which trails are Hiker only; but a more reliable method is usually to call the appropriate ranger station.

The North Cascades National Park covers some of the area you mention (north of Glacier Peak).  They do not allow goats on any of their trails, nor on trails in the National Recreation areas which they manage (like Ross lake).

So you really need to identify the specific trails you are interested in, and then inquire with the appropriate land manager.

Thanks, Perry. It's always a good idea to call ahead to the appropriate people.
