23A is closed between Palenville and Haines Falls. The hairpin turn at the start of the Kaaterskill Falls trail suffered a rock wall collapse beneath the road, and is closed to all traffic and pedestrians. The
NYS DOT website has the following ominous warning:
KAATERSKILL FALLS IS CLOSED - THERE IS NO ACCESS FROM ROUTE 23A. THIS IS IN AFFECT UNTIL THE ROAD REOPENS. TRESPASSERS WILL BE PROSECUTED. The road is not expected to reopen until November. As Tom mentions the falls can be accessed from above.
And BTW the much beloved and well run
Catskill Game Farm has announced that it is
permanently closing October 9. Declining attendance is the major cause for the impending closure. So it is good that you are planning to visit soon. I need to get there myself. There is a grass root effort to
Save the Catskill Game Farm.
At the top of the Platte Clove Road (a local detour for 23A) is the Platte Clove Preserve. I believe there are detour signs from the
start of Blue Mountain Road on NY Rt 32 (a short distance south of the flashing light junction of Rt 32A/32). Stay on Blue Mountain Road and then a right turn on West Saugerties Road which eventually becomes Platte Clove Road.
At the top of the Platte Clove Road you will pass an informal parking area on the left, pass over a stone bridge, pass a dirt road on the right (Kaaterskill High Peak trailhead, Long Path to the north). And then just before another bridge there is parking along the left/south side of the road for the
Platte Clove Preserve. There are two trails here, both described in the prior link.
The Long Path heads south towards the Devil's Path, Echo Lake, and Overlook Mt. The first part of this is a interpretive nature trail, green diamond shaped blazes. It passes over a kingpost bridge. On the far side you can detour to the left (east) where there is a 5' old mill cascade. Back on the trail are several historical and nature guideposts. I think the last station is at a small bluestone quarry. Beyond that it is just the Long Path leading to other destinations, and probably not that interesting to your children.
The more popular trail leads to the 50' Plattekill Falls in 0.2 mile, 15 minutes. It starts down the driveway of an "artist in residence" cottage. The blazes I believe are blue. Generally very easy grade. There was a reasonable flow of water last week, similar to that what is seen in the fourth photo
here.
