Our biggest, favorite event weekend of the year celebrates Year 19 in 2026,
with this main event on Saturday July 11.
This event will run with the same focus on fun, featured activities you've come to expect at past Tri-State Treasures events in the past, with great caches, fun activities for attendees of all ages, our Gadget Forest with all-new gadget caches that you can do on site without, and lots of chances to meet and mix with geocachers from far and wide. All of this takes place in Airport Park, Matamoras PA, and we will also unveil several new sets of geocaches for hiking, easy walking, short driving, and kayaking.
We will have geo-activity before lunch and games and activities for the whole family after lunch, all as part of our annual picnic event in the Vocci Pavilion at Matamoras Airport Park. If you're new to our event or if this will be your nineteenth TST you've attended, know this: we've always prided ourselves on having a variety of fun for all geocachers who attend. You can expect a lot of our traditional activities that have been a part of our picnic since June 2007, and we've got new things to add.
DON'T MISS IT! Make your plans now to be part of Tri-State Treasures XIX, the continuation of our traditional celebration of the Summer season!
