Mt. Deception Climb

Guided Mt. Deception Climb with Pacific Alpine Guides


The highest peak in the eastern Olympics and the second highest in the range after Mt. Olympus, Mt. Deception offers a rewarding climb on a big mountain. Despite it’s relatively non-technical nature, there’s still plenty of excitement to be had. In spring and early summer conditions we climb the Northeast Chute, a steep 45°+ degree gully. Later in the season the route becomes a steep scramble on rock, still requiring crampons to cross an old pocket glacier below the summit.

Our first day of the trip is spent hiking into Royal Basin, one of the most scenic campsites in Olympic National Park. With an alpine start, we climb on day 2, pack up camp, and hike out to the trailhead.

We meet at Sequim Bay State Park at 8am for introductions, gear check, and final preparations. From here it’s about a half hour drive to our trailhead on the Dungeness River.

The hike in to Royal Basin takes a full day, gaining 2500’ of elevation over the course of 7 miles. For most of the ascent we follow Royal Creek, hiking through old growth forest, across avalanche paths, and into the subalpine zone.

We’ll set up camp in the vicinity of Royal Lake, and make preparations for our ascent.


With an alpine start we begin our climb. From camp the route ascends into the upper basin and we find ourselves beneath the broad, intimidating Northeast face. From here we ascend progressively steepening slopes towards the Northeast Chute (early season). The Northeast Chute is steep and direct, and we front point our way up this gully using our ice axe, crampons, and the rope. This is the most spectacular section of the climb. Topping out on the summit ridge, it’s a short cruise to the top.

Later season we’ll ascend to the Deception-Martin Peak col and descend a short distance to a glacier on the north side of the mountain, climbing a few hundred feet on snow, with one or two steeper sections. This puts us on Deception’s north ridge, and the last 400’ is a cruise.

On top we hang out for an hour or so, eat lunch and take in the views before descending back to camp. We pack up our camp and after a short break begin our hike out to the trailhead.

Our favorite option for this program is a lightweight synthetic mountaineering boot with a half-length shank such as the La Sportiva Trango S; great for summer alpine climbing and fairly comfortable to hike in.
Mountaineering boots: A lighter weight boot is ideal (ex: La Sportiva Trango S Evo GTX – Men’s | Women’s).
Sandals (optional): For around camp. Should be as lightweight as possible.
Gaiters (optional): Provide a clean interface between our pants, boots, and crampons (ex: OR Flex-tex).
Socks: 2-3 pairs (wool or synthetic) that work well with your boots. Keep in mind that warmth comes from good circulation, not necessarily heavy socks. If your boots are roomy choose a heavier sock, if they’re snug choose a lighter sock.

Sunglasses: Glacier glasses or dark tinted wrap-arounds, should have full UV protection. Consider bringing an extra pair. (ex: Julbo DolganRENT

Lunch Food: In the mountains, “lunch starts after breakfast and ends before dinner”. In other words, on a given day we generally won’t stop for a formal lunch break, and instead we’ll snack all day long. This is vital to maintaining high energy levels in this environment.

Be sure to bring foods that you like and emphasize variety. Energy bars and gels are great but in limited amounts – real food works just as well and tastes better.

Breakfasts & Dinners: Bring meals that can be cooked with just boiling water. Examples include freeze-dried pouches (Mountain House, Backpackers Pantry), ramen noodles, instant oatmeal, etc. The stoves we use are very efficient for heating water but are not suitable for actual preparation.
