Welcome to Nature Sleuths!

Join the hunt for hidden treasure! Not the lost coins of yesteryear but something far older. Grab your gear and set out solo or with other adventurous explorers. This all ages, family-friendly treasure hunt will take you through old growth forests, hidden urban gems, beaver ponds, marine beaches and much more!

Using the GooseChase app on your tablet or smartphone, explore and sleuth your way through one or many missions at 21 beautiful parks located in Thurston County.

Play along with the Goose Chase app and complete each park’s mission to receive a park-specific Nature Sleuth sticker and be entered into a drawing for cool prizes! The more missions you complete, the higher your chances are to win!

Join us April -November with prize drawings (one prize per group) held on June 30 and December 1, 2021. Stickers will be mailed directly to participants at the end of each month. Remember to add your current mailing address to your profile to receive stickers!

Take the bus!

Bus route information for each park can be found on the park’s mission page. Just look for the transit icon for more information!
