spring farm is a fun hilly intermediate to advanced area, it starts with an uphill rocky climb (crag trail) which leads to a fun downhill curvy hiking trail (cedar drive). from there it goes to my favorite the ski loop which an awesome single track. the map will show more like farm road blue, north east trail blue which are all awesome trails!
from new paltz take mountain rest road(country road 6) about 5 miles until you see mohonk preserves spring farm on your right. pretty simple. it costs 10$ for a day including parking.
