PADI Open Water — Two days at Lake Hydra
This PADI Open Water session completes the hands-on portion of beginner certification with four open-water dives over a two-day weekend at Lake Hydra (listed address: 4733 Hanoverville Rd, Bethlehem, PA). Students must complete PADI eLearning and confined-water training before attending; the weekend at the quarry is the practical checkout where knowledge is applied under instructor supervision. The operator emphasizes a relaxed, supportive environment and supplies a full rental kit—regulator, BC, 7mm wetsuit and exposure items—plus admission and two tank fills per day.
For travelers based in Boyertown seeking a high-quality introduction to scuba without crossing state lines, this package is efficient: confined-pool skills can be handled locally, then the quarry weekend provides varied open-water conditions and the structure required for an internationally recognized certification. Completing the course leaves you qualified to dive to 60 feet (18 meters) and able to rent equipment or join guided dives elsewhere.

SDI Open Water — Two-day checkout at Lake Hydra
The SDI Open Water weekend mirrors the PADI offering in structure—students complete eLearning and confined water sessions before a two-day open-water checkout at Lake Hydra and perform four dives to demonstrate core skills. The operator notes a $499 per diver price and provides a full rental set, but certain site fees and tank fills may be excluded depending on the package selected. Sessions run Saturday and Sunday and are intended for divers who prefer SDI certification standards or who want an alternate certification pathway recognized by many dive centers.
This option is well suited to travelers who want a streamlined weekend that delivers an industry-standard credential and a hands-on, instructor-led progression. The provider requests a minimum of four students to run some sessions, so travelers from Boyertown coordinating with friends or a local dive club will find the schedule easier to secure. For those wanting local planning assistance, the operator offers a contact email for logistical questions.

PADI Advanced Open Water — Five adventure dives
The PADI Advanced Open Water course focuses on practical skill expansion through five adventure dives, including required deep and navigation dives plus three electives chosen for interest and availability. Delivered over two days, the program minimizes classroom time and emphasizes hands-on learning in open water conditions under instructor supervision. The course raises the depth limit to 100 feet (30 meters) where appropriate and introduces divers to wreck, night, drift or peak performance buoyancy specialties—making it a natural choice for those who want to broaden the variety of dives they can attempt.
For visitors from Boyertown who already hold an Open Water certification and want to accelerate their progression, the Advanced course brings structured diversity: each dive ties knowledge development directly to in-water application. The provider specifies a minimum age of 12 and a typical group size of up to 10 divers; this balance allows for instructor attention while keeping costs reasonable. Completing the course opens new dive opportunities both regionally and abroad.

Sat.–Sun 2‑Day Pass — Full access to the inland site
The two-day pass is a straightforward way to spend back-to-back days in the quarry without a formal course structure—ideal for certified divers or students who need checkout dives arranged by their home center. Schedule notes specify Saturday 8am–5pm and Sunday 8am–4pm with defined out-of-water times. All participants must be over 10 years old and must hold a registration code to book; the operator recommends obtaining that code through a local dive professional or dive center.
This pass appeals to travelers wanting concentrated dive time—either to gain experience, complete required checkouts, or practice skills with friends. Because participants bring their own equipment, it skews toward divers already comfortable managing personal gear. For visitors staying in Boyertown, a two-day pass pairs readily with nearby lodging and a relaxed countryside itinerary, trading instructor-led attention for autonomy and maximum in-water minutes.

Mike's Dives — Small groups and private events
Mike’s Dives offers a flexible, private approach: single-day or two-day class options that you coordinate with an instructor for hands-on, small-group teaching. The emphasis is on close attention and customization—whether finishing certification requirements or working on specific skills. Because these are private events, scheduling and content are arranged directly with the instructor, which works well for travelers who value personalization and uninterrupted instruction.
Private bookings are ideal for those visiting Boyertown who prefer to control timing, pace, and student composition. The operator designates the events as private and not available to the general public, so groups can tailor objectives—checkout dives, remedial skills, or accelerated learning—without competing priorities. As with other Lake Hydra offerings, participants must meet age requirements and any registration-code policies in effect at the site.

Diving Site Single Day Pass — Eight hours at the quarry
The all-day pass grants eight hours at Lake Hydra and is the simplest option for certified divers who want a compact, intense day of diving. It’s promoted as the USA’s top inland diving facility access for the day, with rules that all participants be at least 10 years old and hold a required registration code obtained through a local dive professional. As with other site passes, students are expected to bring their own gear.
This option fits travelers short on time but eager for a high-quality quarry experience: arrive early, do several shore or platform dives, and return to Boyertown the same evening. The structure minimizes logistics and maximizes in-water time, but it assumes competency with personal equipment and the ability to manage personal air fills and weights per site policy.
