Nannie Ridge Trail #98
Nannie Ridge Trail #98 is a Goat Rocks Wilderness hiking route in Gifford Pinchot National Forest. The mapped trail follows a path corridor through forested start terrain and then builds to the Nannie Ridge area before continuing toward high points used for ridge access and connections to other backcountry routes.
A common way people use this route is an out-and-back or extended day hike to Nannie Peak and/or onward to Sheep Lake via the Nannie Ridge alignment. One frequently used pattern is a climb to the Nannie ridgeline followed by a short, steeper side trip to the 6,106-foot summit of Nannie Peak.
From the ridge, you gain access to alpine terrain and the kind of high country country-atmosphere that goes with this part of Goat Rocks: exposed ridgeline walking tied into broader trail networks rather than just a single-purpose spur. The trail is also used as part of longer loops and link-ups that incorporate the Pacific Crest Trail (PCT) and Walupt Lake Trail #101.
Route length varies by turnaround point. Reported round-trip distances range from about 9 to 14 miles depending on where you stop (for example, shorter Nannie Peak options versus longer extensions toward Sheep Lake or onward).
Elevation gain is substantial for the shorter turnarounds too: a commonly cited benchmark is 2,100+ feet total, with the high point tied to climbing to over 6,100 feet at Nannie Peak. Plan for a hard-working uphill profile even before you reach the higher, more exposed ridge segments.
Access and overnight logistics center on Walupt Lake. The typical hike starts at the Walupt Lake trailhead and enters Goat Rocks Wilderness via the Nannie Ridge Trail #98 alignment (Walupt Lake Trail #101 is a nearby companion access route). Wilderness camping requires a self-issued permit for overnight stays, and trailhead parking generally uses a Northwest Forest Pass or an America the Beautiful pass.
Terrain and route connections reflect its designed long-distance use: mapped as a hiking path on ground surface and suitable for horse travel as well as foot traffic. In practice this means hikers should be ready for the real Goat Rocks backcountry feel of ridge travel and network routing rather than expecting a dedicated single destination loop.
