It's over at Skytop, part of the Labyrinth path. I haven't done it, hear it's a lot of fun. There are signs pointing the way at the base of Skytop... exactly where I don't know. Maybe I'll go check it out this weekend.
Great way to spend the afternoon. The trail is on the property of the Mohonk Mountain House (see web site for directions). We went up with our 6 year old. From the parking lot to the start of the climb is 2 - 3 miles depending on how you go. You can't park at the Mohank Mountain House unless you are a guest or having a meal there. The Lemon squeeze is about a mile or so of up - down - under - over scrambling. Some of the stuff is hard... for kids or adults. Some very clostrophobic (sp?) sections also. The treat is to finally make your way up the crevis ladders (maybe 120' total in three or four sections... the last one being very narrow, leaning and overhanging). Once you pop out to daylight you can explore the Skytop tower. Pictures follow:
Could this be any more fun
Yes... you go up that and have to squeeze through that opening up top
