Mt. Adams, with its summit of 12,276 feet elevation, is the second highest peak in Washington State and the third highest peak in the Cascades Range. There are several climbing routes on the mountain, ranging from the "non-technical" South Climb, to highly technical routes that require advance skill, experience, and special equipment. Because of the high elevation, all climbs have a measure of difficulty and danger.
Weather on Mt. Adams can change rapidly. Sudden snowstorms can occur above 6,000 feet elevation at any month of the year. What appears to be a non-technical route can change drastically during these storms. Your safety will be the result of your preparation and good judgment. Climbers should always prepare for bad weather and an extended stay on the mountain.
All climbers need to be prepared to deal with a wide variety of weather, snow, and rock conditions. Detailed information on climbing routes is available from a number of climbing guidebooks. Consult these as you plan your trips. In addition to the ten essentials for outdoor recreation (map and compass, whistle, flashlight, extra food and water, warm clothing, a first-aid kit, sun glasses and sunscreen, waterproof matches, a candle or fire starter, and a pocket knife), equipment should include sturdy hiking boots, ice ax, crampons, and ropes when travelling on glaciers. Be prepared and know your limits.
Mt. Adams climbing routes and summit are within Mt. Adams Wilderness and is protected and managed to preserve its natural condition. It is to provide opportunities for solitude as well as primitive and unconfined types of recreation. Your actions will help all of us care for this unique area.

This trail loops through two forests that stand side by side, but are separated in age by 2000 years. One forest is old-growth Douglas-fir and western red-cedar and the other is a young forest that was originally engulfed by lava flows from an eruption of Mount St. Helens over two millennia ago. This forest encompasses three-dimensional imprints of trees in the old lava beds called lava casts. The boardwalk trail loops through the two forests, and is kid friendly.
