|Iron Goat Trail|
The Iron Goat Trail was built on the site of the former Great Northern railway. The trail was abandoned as a railway passage when a snow slide in the early 20th century killed nearly 100 people, and a tunnel (still in use today) was built instead, turning the abandoned railway passage into a recreational trail. Because of the obvious snow danger in these steep slopes, it's not advisable to hike the trail when there is still snow and slide danger.
A three-mile section of the trail is officially designated as an ADA trail, with a wide path that has a level side-slope and is surfaced with hard-packed gravel and dirt (strewn with pine needles and big-leaf maple leaves in the fall). Because the trail slope is railway grade, power chairs can traverse in either direction, but I would advise manual chairs to start at the Martin Creek trailhead and travel downhill, incorporating some kind of shuttle to bring the car from the upper parking lot to the lower lot.
The gravel parking lot has disabled parking, an ADA outhouse (currently closed), and a non-ADA picnic table. The trail begins with a boardwalk, and it has some sections that travel upon bridges or boardwalks. But most of the trail is hard-packed dirt and gravel.
