The Club

Cascade Orienteering Club is a non-profit organization run primarily by volunteers, that has been creating maps and hosting meets in Washington State since 1977. Today, the club is one of the largest and most active clubs in the country. Based in Seattle, the club hosts meets year-round in the Puget Sound Area, and ventures into the Cascades during the summer.

CascadeOC is a member of Orienteering USA. To find other clubs around the country, visit the OUSA site.

Our Mission

  1. To stimulate participation in orienteering through organized events.
  2. To increase enjoyment of natural resources and respect for wildlife and the environment.
  3. To instruct in land navigation through the use of maps and compasses as part of an active lifestyle.

Cascade welcomes newcomers!

There’s a beginner instructor at every meet, courses suitable for a range of skill levels, and you can do it with a friend. Orienteers are friendly and love to introduce people to the sport. So sign up for an event, and come on out!

There are resources on the Newcomers page, but don’t worry about committing it to memory; it’s okay to jump in! At your first meet, you can talk to the beginner instructor, get advice on which course to sign up for, and have fun.

If you have further questions about getting started, contact Rebecca Jensen.
