This hike is a ~27 mile out-and-back trip utilizing the most panoramic, though also most vertical, miles of a popular 34 mile loop trip in this area (Green Trails #s 14&15).
The hike begins at the Hannegan trailhead and climbs steadily at first, and then steeply, to Hannegan Pass (~4 miles in). On our way in and out, this was the buggiest portion of the trip. Flies, though generally non-biting, were the primary culprits. A 1 mile descent brings you to Boundary Camp, and entry into NCNP.
We continued another 4 or so steep yet spectacular miles to the next campsites at Silesia. Well onto the ridge, these 2 sites are fairly exposed, but boast great views, a bear pole, and a composting toilet. A steep descent to nearby Egg Lake begins just beyond the campsite.
The second leg of our trip went ~3.5 steep miles to Copper Lake, but not before a lengthy layover at the Copper Mountain Lookout.
From here, the views of day one's climb come into full view - Shuksan, Baker, Hannegan, Challenger, Ruth, Glacier, the Pickets. The route onward to Copper Lake alternately climbs and skirts a series of knobs before a steep, switchbacking descent to Copper Lake - three campsites, a bear box, and lots of water.
The return to Hannegan mirrored the entry, though with shorter days due to the largely downhill travel.
Hints: Reaching Silesia makes for a fairly strenuous first day on the trail. However, bugginess decreases on the ridge, and is horrendous earlier in the trip--Some snowmelt water is available on the ridge. We unnecessarily loaded up at Boundary Camp, and then began the steepest part of the climb.--We planned our trip for a wednesday - saturday and were alone until our last day. Weekends are sure to be busier.
Wildlife: Marmot, pika, fish in Copper Lake, owl at Silesia, ground squirrels
Trail Snow: A few small patches between the lookout and Copper Lake.
