Form a family, adult, or senior team to test your navigation skills and complete fun and exciting mental and physical challenges on the beautiful trails of MLTNS. As a team, you will read a map and navigate the trails to discover challenge sites and collect as many wooden coins as possible in 2 hours. Challenge sites require the team to complete a task to earn a coin. Teams must remain together throughout the 2 hour event. Prizes will be awarded to top finishers in each category.

Teams consist of 2-5 individuals. A Family Team consists of at least one adult and one child between the ages of 6-15. A Kids only with Chaperone Team consists of 1-4 children ages 6-15 and one adult (over 21, prefer parent) that does not participate in challenges. Participants in an Adult Team are all 16 and up, and a Senior Team consists of participants all over the age of 55.
