16 mile loop, with a total of approximately 7000’ total elevation gain, not counting several wonderful side trip options with a daypack. Max daily gain 3000 feet; max daily mileage 6-8 miles with full pack.

The Teanaway country presents an early-summer wildflower and view extravaganza, and this loop takes you face to face with the backside of the Enchantments and the craggy face of Mount Stuart.

We’ll arrange pickups at participants’ homes at around 6AM on Friday morning, and drive to our trailhead off the Teanaway River road beyond Cle Elum – about 95 miles and 2 hours from downtown Issaquah.

Carpools will be encouraged – details will be coordinated the week prior to departure. A NW Forest Pass will be required for each vehicle.

Riders will be expected to bring $22 each for their carpool driver.

Early July weather in the Teanaways is generally good, 60s during the day and low 40s at night, but participants must be prepared for possible rain and temps that could dip to freezing. Bring a good rain- and wind-proof shelter, non-cotton layered clothing and raingear plus a sleeping bag that will keep you comfy down to 35 degrees; as well as your 10 essentials of course! Please test your stove, headlamp, water treatment system, rainproof shelter and gear to be sure they’re working before the trip! The leader will encourage and coordinate sharing of gear in advance.

The route is rated Strenuous, though our days walking with a backpack will be relatively short, 6-8miles, to allow plenty of exploring on peaks and ridges around our camps. We will maintain a moderate pace (1.5-2 mph on the climbs, 2-2.5 on the flat).

The high point of the main trail is 6200’, with possible side trips where safe (in likely patchy snow) as high as 7200’. On the first night we’ll aim for the established camps below Navaho Pass, but on the second night we’ll choose our own camp as we travel the high ridge between Navaho and Iron Peak. We’ll start our days with the sun, getting on the trail by around 8AM and setting up camp at 2 PM each day.

Participants must be in good condition, able to negotiate some rough rocky trail sections and to travel at the posted pace with only occasional rest stops. Water can be limited on the high ridge sections, so bring capacity to carry 2-3 liters to a dry camp if needed, though along much of the route we’ll collect and treat or filter as we walk. Trekking poles are strongly advisable, as we may be taking side trips up slopes with some residual snow. Streams may be running high such that wading is necessary. Camps may be buggy, so headnets and plenty of repellent are recommended. Please bring the trip map in a rainproof zip-loc or map cover, and be prepared to use it. The leader will offer assistance to participants to help them get to a target fully-loaded pack weight of 30 pounds or less.

The trip may be cancelled or moved without much advance notice if weather or snow conditions are poor.
