Wallowa River Loop Backpacking Guide


The Wallowa Mountain Range, located in the Eagle Cap Wilderness of eastern Oregon, is one of the most stunning areas to backpack in the Pacific Northwest. Often referred to as the “Alps of Oregon”, the immense granite peaks of the Wallowas are best experienced on multi-day backpacking trips.

This 36-mile Wallowa River Loop Trail will take you over some breathtaking mountain passes and still ensure that you get a chance to take in the beauty of the Lakes Basin. Over the course of this loop you can expect to see crystal clear lakes and streams, wildflower-socked meadows, and granite peaks that will make you wonder if you’re still in Oregon.

There are also very worthy side trips to the summit of Eagle Cap and Matterhorn that will further solidify your appreciation of the Wallowas. Although this trail sees its fair share of hikers, we think it's well worth a visit.

In general, late July to September is the best time to travel to this area. Snowpack is a key factor for trip planning in the Eagle Cap Wilderness. Some years a heavy winter snowpack and early season storms will keep trails covered into July. On warmer years with lighter snowpack, June backcountry trips are quite feasible. The same is true for autumn hiking, some years early snowstorms make this area inaccessible and other years it’s stable into October. You can always contact the local Ranger Station to ask about snow level and accessibility.

July and August are usually great for wildflowers, but that’s also the time when mosquitoes will be the worst. Use a combination of permethrin on your clothing and a small amount of 30% DEET on exposed skin for full protection. Mid-August through September can also be a good time to visit this area because crowds and bugs will be lessened.

Always pay close attention to the weather forecast before your trip and be prepared for changing conditions.


  • Total distance: 36 miles

  • Total elevation gain: 7,500 feet

  • Overall difficulty: moderate to difficult

Difficulty depends on your experience, physical fitness, pack weight, & weather conditions. This is not a technically demanding hike, but there are a few big climbs and descents on this trail. Climbing over Polaris Pass is the most demanding portion of this hike with the trail on the west side of the pass being mostly scree.  Be careful, go slow and watch your footing.

Hiking with lightweight equipment will help make this trip easier and more enjoyable. Check out my Gear Guide for my favorite backpacking equipment.


The Eagle Cap Wilderness is a popular hiking destination and the Wallowa River Loop is one of its more popular trails, so you shouldn’t expect to be alone on this hike. That said, we were surprised by how few other hikers we saw on the east side of Polaris Pass. Once we reached Glacier Lake and headed into the Lakes Basin, we started to see a lot more travelers.

To avoid the crowds, try to hike this trail mid-week and either before or after the summer rush from mid-July to mid-August.


The Wallowa River Loop can be completed in 4-5 days depending on your physical fitness level and desired pace. Because this hike is a true loop, you can hike it in either direction. Below is a general route summary heading in a clockwise direction. Before you hit the trail, make sure to consult a detailed map with trail numbers and milage. Also, make sure to consult your map at trail junctions because the signage can sometimes be a little confusing.

  • Begin your hike at the Wallowa Lake Trailhead, near the south end of the lake

  • Follow the East Fork Wallowa Trail until you reach Aneroid Lake. There are some good campsites along the lake.

  • Continue ascending up and over Tenderfoot Pass and onward to Polaris Pass, following signs for Polaris Trail. Take a moment to enjoy Polaris Pass. It’s arguably one of the best views in the Wallowas.

  • After the pass, descend through a well-graded, but long set of switchbacks and follow the trail to Frazier Lake.

  • At Frazier Lake, take trail towards Glacier Lake and Glacier Pass. There are some nice campsites close to Glacier Lake. Get ready for some stunning sunrises and sunsets as well.

  • After Glacier Pass you will begin descending down into the Lakes Basin Management Area. Follow signage heading towards Moccasin Lake.

  • You’ll then meet up with the Lakes Basin Trail, which will wind you through some stunning, crystal clear lakes and campsites.

  • The Lakes Basin trail eventually meets up with the West Fork Trail, which will lead you through beautiful Six Mile Meadows and back to the Wallowa Lake Trailhead.


  • Currently, there are only a few map options for this area, both of which are unideal for backpacking trails and milage. Imus Geographics and the U.S. Forest Service are the two options and they are often out of stock online. You can also look for the Imus Geo map at REI, but it’s often out of stock there as well. When we completed this loop, we stopped at the Ranger Station in Joseph to purchase a map.

  • Backpacking Oregon - This book is an excellent resource for the Wallowa River Loop and many other backpacking trips around Oregon. I highly recommend picking this book up if you like backpacking around the PNW. It’s got great play-by-play descriptions of this trail and is very useful when planning out camping locations and side trips.

  • Hiking Oregon’s Eagle Cap Wilderness - A practical, well-organized and thorough book about the various trails in the area complete with maps, trail descriptions, elevation profiles, and photos. This book contains information about backpacking trips as well as day hikes.

  • The Outbound Collective - A detailed description of this route, complete with trail numbers and mileage between sections.

  • Go Team Darley - A descriptive blog post on this loop with lots of good photos to get you excited.


Below is our summary of the regulations for this area. For the official regulations, please visit the USFS Wallowa-Whitman Recreation page.  

  • Leave No Trace - If you pack it in, pack it out

  • No Motorized Equipment

  • No Bicycles

  • No Groups Larger Than 12

  • No Groups Larger than 6 if camping in the Lakes Basin Area

  • No Shortcutting Trails or Switchbacks

  • No Damaging Live Vegetation

  • No Entering Restoration Areas

  • No Camping Within 100 feet of any lake or posted wetland

  • No camp fires within 1/4 mile (1320 feet) of the following lakes: Bear Lake (Bear Creek Area), Blue Lake, Chimney Lake, Dollar Lake, Eagle Lake, Frazier Lake, Little Frazier Lake, Glacier, Hobo Lake, Ice Lake, Jewett Lake, Laverty Lake, Maxwell Lake, Mirror Lake, Moccasin Lake, Prospect Lake, Steamboat Lake, Sunshine Lake, Swamp Lake, Tombstone Lake, Traverse Lake, and Upper Lake.


Water is plentiful along this trail and is easily accessible from lakes and streams. Carry plenty of water to get from one source to the next and a lightweight water purifier. My current favorite is the Sawyer Squeeze and I highly recommend grabbing one for your trip.


There are black bears in Wallowa-Whitman National Forest, however it’s not very common to see them along this route. Even if you don’t see any bears, there will still be plenty of smaller critters that will want to get into your food supply. And they’ll be happy to chew through your expensive backpacking gear to get after it. For that reason, food protection and storage are very important considerations in this area.

Make sure you know how to hang a bear bag properly or carry a food storage container. Bear canisters and Ursacks are the most effective storage methods and the easiest to use. There are no food storage requirements for this area, but you should always store your food properly in the backcountry.


If you have the energy and time, there are two incredible side trips off the Wallowa River Loop Trail that will reward you with panoramic views of the Eagle Cap Wilderness. The Matterhorn and Sacajawea Summits and Eagle Cap Summit trails will not disappoint.


You will begin and end your trip at the Wallowa Lake Trailhead, which is located at the south end of Wallowa Lake. If you’re headed clockwise, you will begin your hike at the East Fork Trail, heading toward Aneroid Lake.  If you begin counterclockwise, you will begin your hike on the West Fork Trail, heading toward Six Mile Meadows.  This is a true loop, so you can go in either direction. However, some argue that climbing up Polaris Pass from the east can be more challenging, but is still totally doable.


It takes roughly six hours to reach the Wallowa Lake trailhead from Portland.

Driving Directions:  From Portland, follow Interstate 84 East. Take exit 261 from I-84 E toward La Grande/Elgin. Continue to follow OR-82 East to Power House Rd in Wallowa County.  You will arrive at Wallowa Lake Trailhead.


I hope this guide helps you plan a trip along the Wallowa River Loop Trail. It’s one of our favorite places to backpack in the Pacific Northwest so we hope you will enjoy your trip and help preserve our beautiful wild spaces.
