Backpacking Mt. Rainier
Join REI Adventures this September to hike a section of the famous Wonderland Trail that circumnavigates Mt. Rainier, Washington’s highest summit (14,411’). An exciting backpacking adventure for strong hikers, this trip promises outstanding natural beauty at every twist of the trail. The 40-mile backcountry route along the Northern Loop Trail is through gorgeous wilderness where rugged peaks studded with massive glaciers tower over alpine meadows, sparkling lakes and ancient forests where deer, marmot and bear flourish. Early September is an ideal time to be hiking – the colors are lovely, the temperatures mild and the summer throngs are gone. You can count on lots of challenging ups and downs with constant views of the big mountain, Rainier – the most heavily glaciated peak in the lower 48. Two top REI guides will surprise you with delicious backcountry feasts while providing instruction in backcountry navigation, minimum-impact travel and more. Finish off this adventure with a stay at a mountain lodge.
Important Notice: Day 1 is the day you should plan to arrive at the meeting point for the trip. This may require departing your hometown one or more days in advance.

Things to Consider
- Please remember to always pack essential items such as appropriate identification, money, eyewear, a change of clothing, hiking boots and medications in your carry-on baggage, in case your luggage is delayed.
- You can leave your travel luggage and clothes at a secure location on Day One (more details in the Final Bulletin). You will want to bring with you, in a separate small bag, a change of clothes for the last night at the lodge. This bag will stay in the locked vehicle, at the trailhead, during your week of hiking.
- Your pack should weigh 30-pounds or less depending on your physical size and your gear choices. Remember, you will ADD to your pack your share of the group gear: tents, stove, food, fuel, cooking equipment, etc. This will take up additional space in your pack and weigh about 20-25 pounds.
- Cotton is wonderful in warm weather. However, once it becomes wet, it will drain your body heat. Bring wool or synthetics such as Capilene, MTS and Thermax.
- Always test your layers before a trip. Your outer layer should fit easily over the inside ones without binding and bunching up.
- Make sure boots are broken-in. Bring moleskin for foot treatment. Thin liner socks worn under regular hiking socks may minimize the risk of blisters. The liner sock should be synthetic, not cotton. Test your sock combination before you go on the trip.
- Stuff sacks are great for sorting gear. Use different sizes/colors to differentiate contents.
- Sleeping bags come in many sizes and shapes, down or synthetic. Both work fine, but bring one that is easily compressable. It should not weigh more than 3 1/2 lbs. If you are a cold sleeper, consider something with a 15 degree rating and make sure you bag has a hood.
- Trekking poles are a favorite of many hikers when they become tired or wish more support going over rough or slippery ground. In addition, they are an immense relief to your knees on steep ascent and descents. They weigh about a pound and are collapsible.
