About Mount Constance

Mount Constance is a high, rugged peak in the Olympic Mountains of Washington State, rising to about 7,756 feet (2,364 metres). It is known for steep, exposed rock and alpine routes rather than simple walking tracks.

Ascents typically require route-finding on rocky ridges and can include snow or glacier travel outside the late summer window, so the mountain is most often climbed by experienced mountaineers. The summit provides wide views across the Olympic range and toward the Strait of Juan de Fuca on clear days.

The peak is a prominent part of the northeastern Olympic massif and lies within the greater Olympic National Park region. It sits on the Olympic Peninsula west of Puget Sound and northwest of Seattle.

  • Elevation and terrain: Summit elevation is about 7,756 feet / 2,364 metres and the peak is known for steep, exposed ridgelines favored by experienced climbers.
  • Visibility: The mountain is part of the Olympic Mountains and is visible from parts of Puget Sound on clear days.

Tips for Visiting Mount Constance

  • Aim for late-summer clear days and start well before dawn - Mount Constance sits in the alpine core of Olympic National Park and afternoon winds and storms quickly make exposed rock routes hazardous.
  • Treat Constance as a technical mountaineering objective rather than a walk; most parties underestimate the sustained route-finding and exposed rock, so bring proper alpine gear, rope skills, and up-to-date route descriptions or hire a guide.
  • You will need an Olympic National Park pass for access and should expect long approaches; many visitors miss scouting objective hazards and the descent route in daylight, so reconnoiter the exit line and turnaround times before committing to the summit.
When to Go

Best Time to Visit Mount Constance

Best visited in summer (June-September) when snow-free windows make routes and approaches most accessible.

Summer
June-September · approx. 5-15°C (summit daytime)
Milder weather and the best window for hiking and scrambling; most snow on routes has melted and approaches are more accessible.
Late spring / early summer
May-June · approx. 0-10°C
Snowpack is lingering in higher gullies and on north aspects-expect snow travel and route-finding challenges.
Winter
November-March · approx. -10-0°C
Heavy snow, avalanche risk and very cold conditions-appropriate only for experienced mountaineers with winter gear.
