Hiking East Fork

The East Fork Trail offers a continuation of the Mine Shaft trail, which in turn begins at the Clay Pit Road. Though they're somewhat uninspiring names, the route is a great one for kids or a casual day outside. 

It is a quiet forest trail with small creeks and ponds, a vista of the Clay Pit, and plenty of mining artifacts. Connect to Mine Shaft trail and Fred's Railroad for longer jaunts.

Wheelchair Accessibility

If you enjoyed Fred's Railroad trail easy to handle, try this route to see how far you can go before turning around; completing a full loop with Mine Shaft and Clay Pit Road will probably only be doable with an off-road chair. If you really want to see the Mine Shaft and Jerry's Duck Pond, approaching from the Mine Shaft Trail via Clay Pit Road is easier of the options.

When starting from Fred's Railroad Trail, this trail starts off moderately accessible, in similar shape as Fred's Railroad. It's plenty wide for wheelchairs, and is a hard-packed dirt surface with some loose gravel, and the occasional larger rock. At first, there aren't many roots across the trail, but over it's course, the trail slowly gets narrower and more rooty as you approach Jerry's Duck Pond, and the Mine Shaft. The most inaccessible spot is right next to the duck pond where there is a bit of a squeeze through some trees with a lot of roots. Could be passable to some off-road chairs. It is generally uphill from Fred's Railroad towards the Mine Shaft, however it isn't especially steep nor is there much cross-slope.
