The WTA description is confusing as it conflates the two Martin Peaks in WA. The driving directions and map are for the one in the Sawtooths but the description matches the Martin Pk in Glacier Park. The Martin Pk in the Sawtooths is an easy Class 2 climb with no equipment required and no exposure.
The Crater Creek TH (aka Eagle Lakes Trailhead) has an adjoining Campground. There is good camping at Cooney Lake, which is has multiple horse campsites.
If you are going to climb Martin, it is an easy hike over to Switchback Mt. I found the best route was to head NW from Cooney Lk to the saddle between the two peaks, walk the ridge to Martin and then walk it back to the summit of Switchback. From there a nice round trip is to head SE and intersect the Cooney Lake trail (#434) at the head of the Angel Staircase (a pass). This takes you back to Cooney Lk.
