Hoyt Arboretum Permanent Orienteering Course

Practice your O-skills in one of the most beautiful park areas in Portland, Hoyt Arboretum.  This area has a very dense network of trails, some fairly steep terrain, and of course many unique trees to enjoy.  You can bet this course takes you to the best hidden pockets!   The entire course is officially 2.8 km (as the bird flys), but your actual walking distance will be more like 4+ km.

Unlike a normal O-course where the control points are flags placed the morning of the event, this permanent course uses fixed objects such as, signs, trees, etc. At each control point marked on the map, your course question sheet has a multiple-choice question about that point. Answer it, then move to the next control.


  •  The course starts and finishes at the large A-frame picnic shelter across from the Hoyt Visitor Center (see map below).
  •  Visit the controls in the proper order (1, then 2, then 3, etc.)
  •  Complete the course all at one time.


  •  You can start anywhere you want.
  •  You can walk as much or as little of the course as you like.
  •  You can visit the controls in any order. Just get out there and have some fun!


 - You do not need a compass to do the course, only decent map reading skills.
 - This is steep and sensitive terrain and a high use area, so please stay on trails at all times -  no cross country travel.
