Riri Diving is located beside Tiexian Main Road, near the Tiexian Big Bull. The interior features a blue-and-white color scheme, with a bright and clean classroom space and simple storage lockers. It primarily offers snorkeling, introductory diving, and SSI & PADI scuba diving certification courses. During winter, instructors relocate to Xiao Liuqiu to continue teaching, so you don’t need to worry about seasonal interruptions to your learning.

Beginners need not worry—Riri Diving maintains a 1:2 instructor-to-student ratio. They also organize regular domestic and international diving trips each year, from Lanyu and Green Island to Bohol and Palau, allowing learners to enjoy diving in a supportive environment and continue sharing the joy with a community even after certification.

This time, we experienced diving at Hangwan Underwater Mailbox, one of Penghu’s most famous dive sites. The introductory diving fee includes one postcard that can be mailed anywhere in the world. After descending, a professional instructor leads you to personally drop the letter into the mailbox. Instructors also guide your underwater posing, such as how to create bubble rings with your hands. Paired with a TG6 camera and strobe setup, the final results were extremely satisfying!

Ocean Path Diving Shop is located in Wude Community, about a 5-minute drive from the famous Hangwan dive site. The teaching facilities and space are comfortable and spacious, with password-locked lockers for guests. In addition to introductory diving, Ocean Path offers CMAS scuba diving certification, boat diving, night diving, and various diving programs for different needs and skill levels.

What makes Ocean Path special is its own air-filling station, ensuring clean air supply for tanks. All diving equipment is from the renowned brand Scubapro, kept in excellent condition. For guests particular about air quality, choosing Ocean Path offers complete peace of mind!

This time, we experienced a Fun Dive at Ocean Path. The instructor first reviewed the names and usage of all equipment and then selected a suitable dive site based on our previous diving experience and tank usage, making the experience feel highly customized and perfectly aligned with our expectations!

Our dive site was Huoshanshan (Flame Mountain), where we explored underwater basalt formations and observed small fault-line ecosystems. There were slight waves before reaching the site, and the instructor kindly asked if we needed assistance. Throughout the dive, we were amazed by the instructor’s sharp eyesight—many small creatures often overlooked, such as sea slugs and sea straws, were instantly spotted and illuminated with a flashlight for us to observe, offering a new perspective on diving enjoyment. After the dive, hot tea and snacks were provided to warm us up quickly—truly thoughtful and heartwarming.
