I have been putting together an annual multi-day backpacking loop trek for my friends for the last 8 years. The goal was to find a 4 or 5 day trek of moderate difficulty based on a loop to simplify travel logistics. The first trek was through the Sisters Wilderness in 2011 and during each trek we would ask other backpackers what they thought was another great loop option. This advice truly led us to discover and confirm the finest multi-day backpacking loop treks in the Pacific Northwest. Since I have answered this question for other backpackers through the years I decided to create post to highlight these loop treks. The order presented is based on the order in which I discovered these treks. Please feel free to share your similar favorite loops.
There is a 50 mile loop that encircles the 3 Sister Peaks, however, I selected an approximate 35 mile route that starts from the Lava Lake Trailhead and cuts through between the Middle and South Sister peaks. This was my first multi-day trek for which I named the post “No Pain No Gain“, reflective of efforts and rewards of backpacking. The route adhered to the 4 to 5 day goal while adding the challenge of being up close to the Sisters. I would recommend the clockwise route with attention paid to water availability on the first day. Camp Lake through to the Chambers Lakes typically presents the challenge of climbing through snow but you need to experience the view from up there. You have to time this trek to allow for the snow crossing while also taking in a maximum floral display without too many bugs. The east section which is the PCT takes you through lush forests into lava fields. Passing through the restricted Obsidian area is not a problem, however, you want to time your climb over Opie Dilldock pass during the cool part of the day. The Mattieu Lakes near the start and finish offer good rest options. You could also consider doing this loop from the Pole Creek Trailhead.
The Eagle Cap Wilderness was enticing, however, piecing together a loop was not as obvious. I settled on using the Two Pan Trailhead to enter via the Minam Lake Trail and returning via the East Fork Lostine Trail while taking in all of the options provided by the Lakes Basin area. This loop requires crossing the 8548′ Carper pass to settle around Mirror or Moccasin Lakes. Here you have the option of expanding the loop up and over Glacier pass through Horseshoe Lake to Douglas Lake. Or you could just base from the basin area and do a few day hikes to fill your trek. Either way you must experience Glacier Lake. The lakes here are deep and can provide some good fishing. You come out completing the loop via the East Fork Lostine Trail with a shrinking awesome view of Eagle Cap.
Goat Rocks should end up on everyones list, however, with that popularity come the weekend crowds. The loop option is fairly defined with a starting point at the Berry Patch or Snowgrass Flats Trailheads. It could be treated as a 2 day loop, which is why you include spur hikes north & south on the PCT. Whether you go up Snowgrass or Goat Ridge Trails you will be doing the bulk of the climb and you typically will deal with the worst of the mosquitos and black flies. I like the Snowgrass Trail to the Bypass Trail over to the PCT. Once on the PCT portion of Goat Rocks you have access to Cispus Pass south or Old Snowy north which is worthy of a few nights. Then head over to the Lilly Basin Trail which takes you to the Goat Lake area. The lake is generally iced over, however, the campsite options around there provide an awesome view of the valley and Mt Adams. You may want to hike up to Hawkeye Point and you should be treated to herds of mountain goats above Goat Lake. Your hike out via the Goat Ridge Trail is essentially downhill.
The Glacier Peak Wilderness provides a classic 36 mile backpacking loop that takes you up a glacier to Spider Gap past the Lyman Lakes then over Cloudy and Suiattle Pass by Fortress Mountain and over to Buck Creek Pass and Liberty Cap. This trek is probably the most true loop and it may be the most challenging especially getting up to Spider Gap. You start at the Phelps Creek Trailhead and head up the Phelps Creek Trail as far as you can in preparation for the climb up the Spider Gap Glacier. Camping near the Lyman Lakes sets you up for the next climb to Cloudy Pass and then around to Suiattle Pass where you get your first glimpse of Glacier Peak. If time and energy allow you should consider including a visit to Image Lake along Miners Ridge. As you work your way around to Buck Creek Pass, Glacier Peak is positioned prominently to the west. Find a campsite with a view of Glacier and take a hike over to Liberty Cap. The final hike out is relatively easy from there.
This is a great loop trail around Mt. Hood with views many other mountains. I have decided to do this loop every year because it is so perfect and it provides me with a gauge for my overall health. TT 2017 TT 2018 The TT is approximately 40 miles with a number of potentially challenging stream crossings. The elevation low point is near Ramona Falls at about 3300′ with a high point on the east side at 7350′. There are many choices for a starting point with the most common being at Timberline Lodge. Clockwise is the more common route from the lodge on the PCT which takes you by the Zig Zag Canyon where you should consider detouring up to Paradise Park for an evening. Crossing the Sandy river may be the most challenging before you take in Ramona Falls. The PCT offers you a couple of options, I like the one up toward Yocum Ridge over to Bald Mountain before you head up the Timberline Trail toward McNeil Point. On the north side you cross through some old burns but the beauty is everywhere. Once past the Cloud Cap TH you climb to above tree-line typically crossing many snow fields. Copper Spur is a side trip option and then you work your way down to Gnarl Ridge. All of this area is arid and treeless. Cross Newton creek, pass some waterfalls and head through Mt Hood Meadows Ski Area. The final push is to cross the White River and then climb back up to Timberline Lodge. This final climb can be challenging due to the sandy trail and exposure.
I hope these backpacking loops help you find that perfect trek. I will also throw in another option which is partially a loop, The Wild Rouge Loop diverges from the primary Rouge River Trail up to Hanging Rock.
I leave tomorrow for my annual backpacking trip. This will be five days in the Goat Rocks Wilderness Area in Washington. Going totally offline is a good thing to do. Last time I did this I remember having over 1000 emails to deal with, but life goes on without us. The backpack is ready weighing in at about 37 lbs and I am in fairly good shape having been able to do a few short mountain day climbs this last week. The Cascade Head hike offers spectacular coastal views with a very steep vertical climb. Hart’s Cove ends out on the coast in a secluded cove but it is all down hill (1000 ft vertical) to get there. When I return I will post a trip report to the Portland Hikers Website. Here is a trip report from my first backpacking trip to the Three Sisters Wilderness Area near Bend, OR.
