||From Bradford: Take the 219N, exit left in Limestone and go all the way down Limestone Run rd until it turns to dirt. Follow it about another mile until it comes to the top of a hill and a 4 way intersection. Go right at this intersection and all the way to the end where there will be a parking lot. You will be able to see the rocks from there.
From Salamanca: Take the 86W, exit Red House and enter the park. Either ask a ranger how to get to the rocks or find Thunder Rocks rd on the park map.
