From Rhode Island points south take Rt 146 north to Rt 146A. Take a right on Great Steet and left on St Paul Street. This will bring you to Main Street in Blackstone, MA. Take a left onto Rt 122 (Main Street) and another left on County Street. County Street dead-ends at a parking area on the Blackstone River. Follow the trail to the left until you find the cliffs. The second cliff is the climbable one. If the water is high (Spring) you probably won't be able to get to the base of the cliff without swimming.
