Getting to Thunder Rocks in Allegany State Park
Allegany State Park is fairly large, and the Thunder Rocks area is located off on the eastern side of the park. To reach the area, you’ll have to drive on narrow dirt roads from either of the main areas of the park.
From the Red House area, the drive is about 15 minutes and 6.5 miles
From the Quaker area, you’ll have to drive about 12.5 miles over 25 minutes.
There is plenty of parking at the end of Thunder Rocks Road, which is dirt. There aren’t any marked parking spaces here, but there is room for 20+ cars here.
It is best to plan to visit Thunder Rocks when there is minimal to no snow on the ground. The dirt roads leading to this area of the park are not maintained in the winter, and there can be quite a lot of snowfall in this area.
How to Explore Thunder Rocks
There aren’t really designated hiking trails through the rock city. Once you enter the area, you are free to wander through the formations.
Although in some rock cities, you can explore and climb the rock formations, that is not permitted here. There are multiple reasons for this restriction. These include the risk of serious injury from a slip and fall, as well as damage to the fragile plant life that grows on the rock surfaces.
Be sure to wander through the nooks and crannies formed by the rocks. If you look closely, you may be able to pick out fossil formations or make up names of your own for the formations.
You probably won’t hike more than a mile exploring, but you can spend as much time as you’d like enjoying the area.
Geologic History
Although many of the similar areas in New York and neighboring states are thought to have been formed by glacial erosion thousands of years ago, that is not the case with Thunder Rocks.
Thunder Rocks and Allegany State Park are located in an area designated the Salamanca Re-Entrant. This means that it is part of a small area here that was spared by the glaciers.
With that being said, Thunder Rocks were formed instead by the groundwater and sediment interaction.
If you’re interested in either the geological or the mythological histories of the area, be sure to stop at the info boards near the entrance of the trail. We won’t give away all of the information and secrets here. You’ll just have to explore and find out for yourself!
