I was there this past weekend for the first time. From the point of view of an instructor it is a very nice place. And the instructor price is nice, plus I was able to get a pass to park down on the peninsula. Vis was very good saturday and sunday compared to what is available in SW Pa. And comparable to the nicer Ohio quarries. Air fills were a bit on the high side. But then I was diving doubles. But 12 bucks for a pair of LP 72's? At Gilboa my air was free all weekend. I was there for a con ed class for myself and it was a great class. We did have an OW class drop right on top of our class of 9 on the platform and someone from that group dropped a 2 lb clip weight from the surface that bounced off of the right tank of my rig. Less than 6 inches from my head. That was uncool.
For me though, on the other side of the coin is that it is a 5 1/2 - 6 hour drive. Plus the 27 bucks Pa makes me cough up on the turnpike if I want to take the fastest way. Next is the 36 dollar admission price. Per day. Even if you get there at 2pm. Very unpleasant surprise for my DMC. Even a special weekend 2 day for say 50 bucks would have been reasonable. 72 though on top of the drive and tolls pretty much insures we will not be taking students there. I can hit any of the Ohio quarries in 4 -4 1/2 hours, no tolls, less fuel, and admission is less than half of what Dutch Springs charges. I am glad we went since now I can say we were there but I don't see us going back and me only for training that I deem to be very special like it was this weekend.
We did not eat there so no idea about the food prices. Again it was nice but way too far and expensive for my students to consider. If I lived within an hour then I'd use it and push the season pass deal to my people. But just as a weekend destination to get wet from, my part of the map, nah. More economical choices that give the same results closer to home.
