Letterboxing at Pioneer Park

How do I become a Letterbox Hunter?

1. Pick up a Clue Book starting April 5th from the Mercer Island Community & Event Center (8236 SE 24th St.). Read your Clue Book to become familiar with Pioneer Park and the NW quadrant you will be visiting.
2. Create a letterboxing kit. It’s simple! You just need your Clue Book, a favorite stamp and walking shoes!
3. Letterboxing is in Pioneer Park NW –  Starting June 1st, take your Clue Book with you to Pioneer Park to begin searching for letterboxes. Once you come to a box, open it and stamp the notepad that is in the letterbox with your stamp. Use the stamp that is in the letterbox to stamp your Clue Book. You can also write a note saying you were there with the pencil that is in the letterbox on the notepad. Once you have stamped your Clue Book move onto to find the next letterbox.
4. Take care of the letterboxes! It is REALLY important that you leave the letterboxes exactly how you found them – after all, you want the next hunter to have as much fun trying to find the letterbox as you did! If you find a problem with a letterbox, please email restoration@mercerisland.gov. 
5. Turn in your Clue Book by October 1st to be recognized for your accomplishment. When you turn in your booklet, you will get a prize! Additionally, we are keeping track of everyone that completes their Letterbox booklets because successful particpants wil be recognized at our Open Space Trust Board Meeting in October. 
6. You can turn in your completed Clue Books to the Mercer Island Community & Event Center or mail to: Recreation Department 2040 84th Ave SE, Mercer Island, WA 98040.
7. Have fun and see how many letterboxes you can find!
