About Udo Island Submarine

Dive into the crystal-clear waters off Udo Island's eastern coast on a guided submarine tour that brings Jeju's vibrant marine world within reach of every traveler. Glide past colorful coral reefs, schools of tropical fish, and dramatic underwater landscapes—all without getting your feet wet.

Local Legends & Stories

Udo Island is said to be the tail of a mythical ox that swam across the sea to reach Jeju, and local fishermen still leave offerings at coastal shrines for safe voyages. The waters around Udo are believed to be protected by sea spirits, which is why marine conservation is deeply woven into the tour's educational narrative.

Must Do Experiences

What Makes it Special

Perfect Timing

When to visit for the best experience

Visit between May and October for the warmest water temperatures and highest visibility, which can exceed 20 meters. Weekday mornings during shoulder seasons like April and November offer the best combination of clear waters and smaller crowds.

Photography Guide

Capture the perfect shots

Use a camera with a wide-angle lens and disable flash to avoid disturbing marine life and reducing visibility
The curved acrylic windows can cause glare—position yourself at an angle and use a polarizing filter if available
Capture both the underwater scenes and the dramatic coastal views during the boat transfer for a complete visual story

Cultural Etiquette

Koreans place great importance on environmental stewardship, so respect the no-touch policy with marine life as a sign of appreciation for local conservation efforts It is customary to thank the crew and guides for their expertise—a simple '감사합니다' (gam-sa-ham-ni-da) goes a long way Dress modestly and remove shoes when boarding if requested, as a sign of respect in Korean cultural settings

Special Events & Experiences

Enhanced experiences and seasonal highlights

Summer marine education programs offer guided talks on coral reef conservation for school groups and families
Annual Jeju Marine Festival in September features special submarine tours combined with beach activities and local food markets
Winter expeditions occasionally spot migrating whale sharks and other rare species during colder water surveys

The submarine requires descending a steep set of stairs to enter the cabin, making it inaccessible for wheelchair users and difficult for those with significant mobility impairments.

Morning departures generally offer the clearest underwater visibility, while the spring and autumn seasons provide the most stable weather conditions for optimal viewing.

Passengers should bring a camera for photography, though flash is prohibited, and a light jacket as the air-conditioned cabin can become cool during the submerged portion.

The tour operator will cancel or delay departures if sea conditions are unsafe, and affected passengers can reschedule their booking or receive a full refund.

Guests are required to arrive at least 30 minutes prior to their scheduled departure time to complete the safety briefing and boarding procedures.
