Good to know: Dog-friendly, kid-friendly, huckleberries, fire lookout
There are several ways to get to the still-in-use fire lookout perched on the top of 5,854-foot Thorp Mountain. The Knox Creek Trail is the shortest and like the other trails leading to Thorp, quite scenic. The trail starts high in an open bowl of ferns and flowers and provides viewing nearly nonstop. The way starts off gently with a few long switchbacks before heading more steeply to a small notch on Kachess Ridge. Here among stately hemlocks and abundant huckleberry bushes head right on the Kachess Ridge Trail, dropping about 100 feet before heading up again.
Traverse a high meadow providing excellent views of twinkling Kachess Lake below all the way out to glistening Mount Rainier on the southern horizon. Enjoy good views too west of Meadow Mountain and Mount Margaret. At about 2.0 miles reach a junction with a trail coming up from Thorp Lake—a most worthy side trip or future trip.
Turn left and climb steeply up open meadows and up and around small ledges reaching Thorp’s summit in due time. Check out the 1930-built fire lookout and share conversation with one of its friendly keeps, usually either John Morrow or Lori Gaioss. Take in the spectacular views north of Mount Daniel, the Three Queens, Lemah Mountain and ChikaminPeak. Scan Kachess Ridge and its radiating ridges and contemplate exploring the lesser known trails that grace this lovely corner of the Central Cascades. Don’t to forget to allow some time for huckleberry harvesting on the way back to your vehicle.
