Letterboxing at Pioneer Park

Pioneer Park, SE 68th and Island Crest Way

June 2 – October 31

Return your clue book by October 31st! 

Letterboxing is a fun activity you can do all summer long!

Like a scavenger hunt, letterboxing is an activity where you and your kids can search for clues to find hidden letterboxes throughout Pioneer Park. For each letterbox you find, put a stamp in your Clue Book and stamp the letterbox notepad, too, and don’t forget to leave a note for other letterbox hunters.

Pick up a free Clue Book from the Community & Event Center, Luther Burbank Park Admin Office, or the South End Starbucks.  The Clue Book will help you become familiar with Pioneer Park, and you can start from wherever you’d like. Choose your favorite stamp, grab some walking shoes, and get hunting!
Turn in your Clue Book by October 31 to be recognized for your accomplishment at a Letterbox celebration in November. You can turn in your completed Clue Books to the Community Center, LB Park Admin Office, or mail to the Parks & Recreation Department.

And more!
