This is part of the Gladys Foster Preserve series. The first 10 in the series are along the blue trail. 11 through 25 are along the fire roads. Number 25 is along a road which connects the main fire road to the blue trail. The trail also crosses the road between numbers 21 and 22. 26 through 30 are along a different section of the blue trail. You can start near 30 where the trail meets the road or you can start near 21 where the trail crosses the fire road. Parking is available near "Wyassup Road (10) ~P&G~" cache (on Wyassup Lake Road), along Rt-201 (Cossaduck Hill Road) near number 11, or in the woods near number 1. The entire series could probably be done in a single day with minimal back tracking, although at least some would be necessary no matter which way you go.
