About Gilboa Quarry

Just 20 minutes from Findlay, OH, and conveniently located off I-75, lies the Midwest’s top diving destination—Gilboa Quarry! Whether you're a beginner or a seasoned diver, you’ll be amazed by the crystal-clear, spring-fed waters and unique underwater attractions that Gilboa Quarry has to offer.

 

Originally a limestone rock quarry dating back to the 1890s, Gilboa has transformed into an underwater wonderland! Dive in to explore vibrant marine life and discover thrilling attractions, including a Grumman airplane, Sikorsky helicopter, school buses, and so much more.

Gilboa Quarry isn’t just a dive site—it’s an adventure waiting for you beneath the surface!

 

For those looking to extend the adventure, on-site camping is the way to go! Pitch your tent under the stars or reserve a spot in the RV park (reservations required). You’ll have access to a modern bathhouse featuring hot showers and changing rooms, available 24/7 for your convenience. Prefer a hotel stay? We recommend The Drury Inn & Suites in nearby Findlay. Just ask for the special “Gilboa Rate” when booking!

Diving Protocol:

  • Students must be accompanied by an instructor at all times while in the water.

  • Maximum of 3 dives per day when doing any training, this includes fun and check outs.

  • Plan to be at the trailer from 8:15 AM to 5:30 PM for a full day of diving fun!
    Throughout the day, you’ll have 1-2 hour service intervals between dives to rest and recharge. If you need a more flexible or have a tight schedule, no worries! You can easily arrange for private classes to fit your needs. 

  • We offer several classes on weekends, including open water and advanced courses.  While we strive to stay on schedule, we appreciate your patience as some students may need additional time.

  • If you require extra assistance, we'll do our best to keep you within your class but may arrange for one-on-one instruction to ensure everyone stays on track. This personalized attention helps you build confidence and enjoy your diving experience.

​

Preparation and Briefing:

  • If your group is next, please prepare your gear and stay close to the trailer.

  • Listen to surface support instructions carefully.

  • We need to brief, dive, and then de-brief each session, so it's essential everyone remains nearby.

While waiting, we encourage you to relax, enjoy the day, and connect with fellow divers. Certified divers frequently join us, creating a wonderful community. Please remember, the buddy system is mandatory for all divers; solo diving is not permitted.

​

Air Fills:

After each dive, you must refill or top off your tank. Ensure that your tank has a minimum of 2500 psi before re-entering the water—this rule is strictly enforced with no exceptions.

Steps to Refill Your Tank:

  • After your de-brief with your instructor, take your tank to the main office area for refilling.

  • Don't forget to bring one of the air tags you purchased at check-in.

  • You are responsible for filling your tank and transporting it to and from the air fill station.

 

Lunch Break:

Instructors and support staff will take lunch breaks as time permits, either bringing their own lunch or eating at their campsite. If you are between dives and feel hungry, please eat the lunch you brought with you.

Important Note: If you choose to leave the site to get food, be aware that it may take 1-2 hours for the round trip. This could result in missing a dive, which might not be able to be rescheduled for the same day or weekend.

 

After Diving and Gear Storage:

After completing your dive and debriefing, It's important to take care of your gear. Remember, once equipment is issued to you, it’s your responsibility to take care of it. Please note that gear storage in the trailer is not permitted.

  • Wetsuits: Need to be rinsed and hung up to dry overnight.

  • Rinse and store all other equipment. We recommend bringing a tote to store wet gear in your car, to prevent any loss, theft, or damage.

  • Drop off your tank to be filled, ensuring it will be ready for pick-up in the morning.

  • After handling your gear, you are free to relax at the site or return to your lodging.
