A trip to Franny Reese State Park in Highland, NY was recommended by some of our members at our New Paltz Rail Trail walk. I've checked out info on the park and it looks like a great place for our group. This will be somewhat short (its listed as a 3.6 mile loop) but we can take our time there or take more than one of the trails.
Afterwards, some suggested a trip for the group to the Gunk Haus restaurant in nearby Clintondale: http://www.gunkhaus.com/p/directions.html
The page below has some images from the park. I haven't been there myself but it looks very nice.
We will be meeting at Johnson-Iorio Park, which is at the end of Haviland Road in Highland, NY. If you've been to the Walkway Over the Hudson (Highland Side), its on the same road but all the way at the end.
There is a small parking lot there (so park there if there is room). If it fills up, you can park on one side of the road (the park side, not the other side.
