About Glacier Peak Loop
Glacier Peak Loop is a 132 km hiking route in Washington, United States. It climbs roughly 2,905 m (9,531 ft) along the way. Most people take around 6 days at a comfortable pace, plus stops. Only take this on with mountain experience, solid navigation and a realistic view of your own pace.
Most people walk it in stages, using the waymarking and accommodation built up along the corridor. Glacial terrain changes from year to year, so local information matters more than usual. The higher sections open out completely, with ridgelines stacking into the distance on clear days.
It is a 132 km loop, so you finish where you started and never repeat a section. Much of the surface is sealed, which makes for fast walking and easy going in the wet. It is not consistently waymarked, so carry a map or a downloaded track rather than relying on signs.
It walks well across three seasons, with spring and autumn offering the best combination of light, temperature and quiet paths.
In short, Glacier Peak Loop suits experienced mountain walkers who are comfortable with exposure, navigation and long descents. Dog access is not formally recorded here, so check locally before bringing one.

The route in detail
The loop is usually walked clockwise from the main trailhead. The first third does most of the climbing, so settle into a slow rhythm early rather than trying to hold a flat-ground pace. The upper section is where the route earns its reputation, and it is also where weather changes fastest. The return leg is the reverse of the outward journey, which makes it easy to judge remaining time.

Tips from the trail
- Start at first light. A long day is far more pleasant when you are not racing the sunset on the descent.
- Aim for april to october for the most reliable conditions.
- Download the track to your phone before you leave. Signal is not guaranteed.
- Break the route into stages and decide your turnaround time before you set off.
- Leave nothing behind, including fruit peel, and stay on the marked line to protect the ground either side.
Warnings
- This route is long and sustained. Turn back early rather than late if the weather closes in.
- Glacier terrain is unstable and changes year to year. Do not step onto ice without the right equipment and local advice.
- Outside the main season expect snow, ice or closed access on the higher sections.
Safety
Emergency services in United States are reached on 911. Tell someone your route and expected finish time before you set off, particularly if you are walking alone. Mobile coverage is generally usable along this route, but do not rely on it as your only plan. If the weather deteriorates, descending the way you came is almost always the safer option.
What to bring
- Comfortable, broken-in hiking shoes or boots
- Weatherproof jacket
- At least 1.5 litres of water
- Trekking poles for the descent
- Offline map and compass
- Head torch and spare battery
- Extra warm layer
- Sun hat, sunglasses and high-factor sun cream
- Microspikes if you are walking at the edges of the season
Photography
Shoot the first hour after sunrise from the higher ground: the low angle picks out every ridge and the valleys still hold mist. Because it is a loop, the light changes direction as you go, so save some memory for the back half. A wide lens captures the scale, but a short telephoto is what turns a good view into a photograph.
