Test your navigation skills in a 90-minute treasure hunt through Allardale Park using a map and compass. The individual or team that earns the most points wins. You choose your own route, and walking, hiking or running are all fine. The event is suitable for all skill levels, and beginners are welcome. It starts at 1 p.m. at The Lodge at Allardale. Afterward, stay for a fall social at the lodge. The Northeastern Ohio Orienteering Club hosts.

The map fee is $15 if you pre-register and $20 on the day of the event. Pre-registration is encouraged, and only a limited number of walk-up maps will be available on a first-come, first-served basis. Visit medinacountyparks.com for details.
