Memorial Day weekend backpacked in Trapper Creek Wilderness. An amazing little wilderness with ample campsites and great well-maintained trails.
Our trip consisted of:
Friday night drive from Seattle to Beaver Campground (past Carson, WA and the great Backwoods Brewing co. on Wind River road). We arrived super late and as per usual on Mem. Day weekend, it was pretty slammed. We got super lucky with the last site at Beaver which is just fine car camping with plenty of sites, bathrooms, usual amenities. Recommend doing this hike from the southern entrance on Wind River Rd versus the northern entrance. There is a paved road all the way to TH!
Saturday morning-super short drive to the Observation Peak TH. You just drive up Wind River Rd near Govt Mineral Springs campground and you're right there. We parked and packed up for 2 nights overnight. The debate was which trail to take up, Observation Peak trail #132 or Trapper Creek trail #192. Craig Romano recommends going up Trapper Creek and descending on 132 after reaching the peak. I very much disagree! You should ascend on 132 to the peak and descend on 192. The switchbacks on 192 are gnarly and seriously would be tough to ascend as compared to 132.
So we started going up 132 (it is VERY well-marked and splits off from the the TH and trapper creek. Just take a guide book with you for details on distance. Basically, you follow the signs up to Observation Peak. We had no problems with weather, bugs, trail conditions etc. It was really pretty smooth sailing and extra special thanks to the amazing signage in the Wilderness. It is really visible and well-marked.
We ascended starting at 12 PM and probably made it to the junction the Peak at 5 pm. We walked on to Berry Camp and decided to make camp near there. At Berry Camp (which is really the junction of several trails, including Big Hollow Trail and 132) there is also another campsite in the woods with a primitive firepit. Since it was a little more off the main trails, we actually set up there and not the 'official' Berry camp site. Good thing, because we had more folks come in that night and they set up at Berry. The hike from Berry Camp to the actual Peak is an off-shoot trail, so we actually ditched our backpacks and just scooted up to the Peak and then back down. Amazing views, you can really see Hood, Adams, MSH, Rainier. It is stunning! There is also a clear campsite at the peak, which provided you have good weather and no wind, would be a great place to camp. Difficult to stake a tent though.
Camped in Berry vicinity that night, which also has a stream just a short distance down the Big Hollow trail, so water sources were adequate. KEEP IN MIND THIS WILL NOT BE THE CASE IN JULY/AUGUST. I could easily see it getting very dry and not having the snow-melt we had.
Next day descended down the Trapper Creek trail #192 with a lot of switchbacks and some down logs but nothing to bad. About 6ish miles descending but ample signs the whole way. We got down to the junction of Soda Peaks Lake, Trapper Creek, and 132, and decided to try to head up Soda Peaks Lake Trail #133. Not a good idea at 5pm. It is truly Granite Mtn steep, and 3.1 miles of straight elevation. I would make sure you do this as a full day and leave ample time for the elevation, down trees, etc. So we attempted to head up the trail but it got too late so we headed back down and ended up camping close to the initial ascent of 133, right on the trail. There is actually a great campsite near the creek that is super nice and makes for an easy walk out to the TH the next day.
Monday we headed back out to TH, only about 1.5 miles or so. Signage on 133 to 132 to TH was easy to navigate. Lots of folks were heading in and out on the trail so we exchanged beta. Monday was spent exploring the Gorge: Bridge of the Gods, walk across as a pedestrian! Bonneville Hot Springs, worth the $$, downtown Skamania, nice spot for lunch, river walk, etc. Then the inevitable slog back to I-5 and either to Portland or Seattle. We headed to Seattle and got lucky with the drive-about 4ish hours.
This is a great loop to do for 1 night, or extend it out for two. Highly recommended. Romano's book on the region is a great resource as well.
