Although open to all club members over age 18, this trip is also part of the B3 backpacking Building Blocks series and is eligible for B3 course graduation credit.

To avoid becoming lost among the admiring crowds, we will travel and camp in some of the less-visited parts of this popular area. While this is a strenuous trip, we will travel at a slow-to-moderate pace comfortable for all participants, taking occasional rest breaks as needed.

On Day 1, from the Berry Patch Trailhead, we will hike to our campsite in Cispus Basin, set up camp, then take a side trip to Cispus Pass (7 miles, about 2,800 ft elevation gain). On Day 2, we will hike through Snowgrass Flats and past Goat Lake, then continue along the Goat Ridge Trail to camp in the upper Jordan Basin (Goat Ridge Meadow) (6 miles, about 1,000 elevation gain). On Day 3, we will dayhike out to Hawkeye Point, then return to camp and continue down Goat Ridge to the trailhead (6 miles, about 800 ft elevation gain, including dayhike).

Books: Backpacking Washington: Overnight and Multiday Routes, by Craig Romano (No. 17 Goat Rocks: Cispus Basin); Backpacking Washington: From Volcanic Peaks to Rainforest Valleys, by Douglas Lorain (No. 21 Goat Rocks Circuit); 100 Classic Hikes in Washington, by Ira Spring and Harvey Manning (No. 75, Snowgrass Flat – Goat Ridge Loop).

Because wildlife is common in this area, I recommend that you use either an Ursack or bear canister. Plan to filter or treat your water. Consider bringing insect repellent because bugs are numerous in one lower section of the route in particular.

During the week before our trip, I will facilitate carpool arrangements. A Northwest Forest Pass or Interagency (America the Beautiful) Pass is required to park at the trailhead.

This trip may be canceled or moved if the weather or trail conditions are unsafe during the trip dates.
