Hope you can join us for our 11th Annual Tri-Cities Geocoin Challenge.

If you have never been to our event, this will be the year to make the trek to the beautiful Tri-Cities, WA. Yes, there are four cities involved, but we are still considered the “Tri-Cities.”

For 2021, we will be in Richland again after all of the positive feedback last year on the central location. We are looking forward to a packed weekend of fun.


  • Free, family friendly weekend for new and experienced geocachers.
  • Travel around Tri-Cities (including West Richland) to find 28 out of 32 geocaches and earn a trackable geocoin.
  • Those who complete the challenge will receive a free geocoin. (Limited to one free per household – no exceptions) Coin details in progress.
  • Kids (13 and under) who complete the challenge will receive a prize.

  • TO REGISTER: Log “WILL ATTEND” on this page with the # of people connected to your geocache name.
