Gilboa Quarry - Ottawa, Ohio

Great experience all around! 2 nights camping and 2 days diving was fun! Any skill level divers can be found learning and tweaking. As a diver with many dives I still found the lines tied between sunken objects to be awesome. You can't miss anything!
Cheyenne in the office is so friendly and helpful! The air card is a great deal! There's a small food truck.
We can't wait to go again!

I had so much fun diving at Gilboa quarry this past Sunday. It was my first time there and I was blown away by how clear and beautiful the water was, and by all the submerged attractions. There was even halloween decorations! It made for 3 very exciting dives. Don was the employee who helped us get set up, and he was very friendly and attentive. At one point he and another employee (who I didn't get the name of) gave me and my friend a ride to the bathrooms on the back of their golf cart. It wasn't a far walk, but they went out of their way to make our time at the quarry convenient and fun! I can't wait to go dive there again!

Fantastic place to dive and train.

They have everything you need to get underwater here, including air, BCDs, regs, and wetsuits. They have banked Nitrox at around 31% available.

The water is unusually clear for an inland lake, and the place has a ton of fish, even a lot of trout. They threw some stuff into the quarry you can look at and swim around, such as a helicopter and an airplane.

The east side of the quarry is shallow and contains most of the stuff you'd want to look at. The west side is deep and cold. In July it was 41°F at 110 ft down for us.

They sell fish food for for $1 - and it's worth grabbing a bag. Just beware of how aggressive the fish will be when they discover your purchase.

Equipment rentals here are VERY expensive, so bring your own gear to make it more affordable.

Excellent scuba diving quarry. Free parking up front, and free carts to take your gear to the docks. $15 for parking next to the quarry docks. Lots of camping spots too for tents, or premium spots for RV camping. It’s cheaper and less crowded during the week. Friday - Sunday is a little more expensive.

Portapotties next to the quarry (bring a flashlight if it’s overcast or nighttime), and full plumbing bathrooms with private showers near the entrance. Or you can rent a single cot in the loft area.

Loved it!!! We had a great time as a family including the dogs!!! Was alot of fun for me and my kids my husband did his diving and I got to watch and learn and had some dive time myself. When I wasn't diving me and the kid's with the dogs got to swim in a little area. It was very nice just remember water shoes and bug spray. We camped for 2 nights and everyone was very nice. We are already talking about going back. Super fun place.

This is where my open water certification started, so many years ago. Great controlled environment. So much to see, great open platforms to practise skills, different things at different depths so there is something for everyone. Good spaces on platforms to get geared up and store gear in between dives. Sturdy stair cases bring you from land down into the quarry, with railings. Safety first!! Prices are reasonable to enter quarry and they offer some rental gear if something breaks or you forget. They also do air fills so you know you will have a great day diving. Staff are friendly and courteous. Nice selection of gifts shop items if you're looking for a first time momento or if you been coming here for years, there's bound to be something for everyone. There are flush toilets and showers onsite, which is a huge draw! Don't forget they also offer camping!
