Nantucket Surf School is located on Nantucket Island in the parking lot @ Cisco Beach on the South Shore. Take Hummock Pond Road and take your last left onto a Dirt Road before the "End of the Road". If you get to a dead end road, you've got to far. Turn around and make your first right onto a dirt road. Look for the big white box truck and surfboards.
