How to get there: Between 9 and 9D, there is a new, large parking area on the south side of Stake Hill Road between Avery and Walter Hoving Rd. There is no good address to get you close and Google view doesn’t show the parking lot. It is next to the woods and a big, mowed field. There is a post next to the road that says North Redoubt Trail.
Summary: From the parking area, head east into the trees, paralleling Snake Hill Road. The red trail gradually climbs but has steep drops down into the valley. You’ll follow a stream for a bit and see an old cabin in the distance as you start to pull away from the road.
In less than half a mile, you will veer right at the fork and cairn for the North Redoubt. There is a small window through the trees for a Hudson view and you can still see the rough shape of where the military had their post in the mounds of dirt.
Head back down to that fork and take it right. You’ll cross through a field and see a little ramshackle cabin. Head uphill on the road behind the fence to nowhere. You’ll cross into the Forest School property.
Follow red to the South Redoubt. The view here is more impressive and the ruins are more defined. There is an informational kiosk to see what all the foundations were.
