At 1:3,500 scale, Farrell McWhirter is not a big park, and we long ago outgrew it as a school-league venue. Even so, it is a wonderfully diverse park combining four distinct areas of open ground and picnic areas, flat and wooded trail network, dense fields, and hillside wooded trail network with clear contours.

Cascade typically uses this for shorter, sprint-type events or as a venue for school-based orienteering training. The park has a permanent course.


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 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: 4

The variety of terrain, while helping to make navigation interesting, actually reduces the navigational difficulty. If you’re on a hill, you’re in the contours area, etc.. This puts you quickly in a subset of a small map. So if you do get lost, it’s not very much or for a long time. Perfect for beginner training.

Physical Challenge Rating: 3

Most of the park is flat, without physical challenge. One section does have a six-contour-line hillside, and that earns this park its #3 rating.
