on my first date with my girlfriend before we were even going out (hah no wonder why we date now), she mentioned to me that she went "quarry jumping" somewhere in south county. Well, that sounded very dangerous but because I'm a thrill seeker I just had to find this place. Google maps, satellite views. Found it in westerly.
I went there last summer with a friend. It was a great/dangerous time. Now, I will admit it probably wasn't the smartest idea I've had in awhile, but it was definitely fun. Quarry was shut down a very long time ago, away from the main drag, and down a dirt road. There are two main jumps. One is about 50ft high and the one I jumped off of was about 25ft. Quarry jumping is VERY dangerous, but there were fish in the water and we watched a video someone posted on youtube of them jumping in the water; so we knew the spot where to jump.
This quarry is shut down, but there are other nearby working quarries. We went when it was rainy. I've heard state troopers hideout there sometimes. Just thought I would share another interesting place in RI >>
