By orienteering standards, Beaver Lake Park is a small park. At 82 acres–54 forested–with three simple park loop trails, the navigation is not complex. But with waterfront access on two lakes, playground, large picnic shelter “pavilion” with fireplace, and an all-season fully enclosed lodge, this park does have something for everyone.

This park is ideal for combinations of beginner training events, either with the existing permanent course or participatory set-your-own courses, combined with a picnic location.


This venue features a permanent course, which you can do at any time! To try it out, print the PDF map and control descriptions below (or simply open them on your smart phone), read the instructions on the permanent course page, and have fun!

CascadeOC supports many permanent courses over a large geographic area and our volunteers have limited time to keep up with maintenance. If you observe any damaged, obscured, or missing markers, or if you can help regularly monitor and maintain this permanent course, please let us know. Thanks for your help!

To find more venues with permanent courses, visit the Map of Maps page, where each permanent course is marked by a yellow pin.

The permanent orienteering courses at Beaver Lake Park were designed and installed as a Boy Scout Eagle Award Service Project by Jeffrey McNerney, Boy Scout Troup 571, Sammamish, WA.

The purpose of providing these navigational and physical ratings below is to provide greater context for how challenging an orienteering course at this venue might be. For example, an advanced-level course at a local city park will be easier to complete than an advanced-level course in the mountains.

Navigational Challenge Rating: 2

Navigation generally consists of about three short park loops, about 1.3 miles of trail total, with smaller offshoots and wide grassy areas at both ends of the park.

Physical Challenge Rating: 1

The park is relatively flat, and the trails are disabled-accessible. That said, physical training is what you make it. A park like this with some small loops is ideal for interval or “chase” training to boost running speed.
