The waterfall with a person next to it Fall Brook Falls is a 70 foot waterfall near Geneseo. There is a short hike (30 minute) to walk along the stream. It takes about 45 minutes by car to get to there from Rochester. Getting to the base of the waterfall (and the attached trail) requires traversing a fairly steep canyon wall.
It's a great way to spend an afternoon. Unfortunately the falls is on private property and trespassing is not allowed. Directions: I390 South Take exit 8, Road 20A. Turn right at Lakeville Road.
Lakeville Road turns into South Street. Bear right onto Mt Morris Road - NY 63. After about a half a mile pull off onto the right hand shoulder. There aren't any signs but there may be some other cars parked there.
You'll see obvious trails leading off into the woods. If you have a GPS receiver then use it to find the parking place: latitude 42.77472, longitude -77.82889. Google Terrain View showing Falls Brook - click on Satellite for partial image view Live Satellite View Yahoo Map More Photos
