Welcome to Scarsdale Park. This is one of a favourite rest stops when riding the rail trail. Shade, picnic tables and bathrooms; what more do you want. There is some interesting information at the hut across from the bathrooms.
You are looking for a pipe puzzle cache. Find the cache and then find a shady spot to solve it. Be gentle, it doesn’t need forcing. Please return exactly as you found it as this is a high muggle area. To close cache, line up arrows. Good luck.
