That's all good.There is a mini-mart that's the bus stop in Palenville if you need anything.
All your work the first day is going to be first thing going up.After you get to Kaaterskill HP its an easy trail to Platte Clove Rd.
On your older map it will show a herd path direct across the road towards the lean-to…..that's now a marked blue trail and part of the Long Path.Also just a half mile before you hit Platte Clove there is a yellow trail to the SE to Huckleberry Point(about 1 1/2 miles one way,its a dead end to the point and an easy walk if you are making good time).
If you hike a bit your second day is strait forward.Waters a little low here,but the water in Mink Hollow is dependable,one is off trail down a herd path but easy to find.
Third day is cake…..You'll find the trail to Taylor Hollow easy or you can take the trail to Hunter Ski Area and go down to the Town of Hunter there.
