For about $188.25 per person, you get four dives—deep sea, wreck, and night dives—plus the convenience of overnight accommodation on Koh Tao. This tour is tailored to experienced divers looking for high-quality underwater experiences in a small-group setting.
The itinerary begins early with a ferry from Koh Samui, followed by a short transfer to the diving boat, “Scuba Birds.” The dives include an exciting night dive, offering the chance to see nocturnal marine life, and a wreck dive, which is often a highlight for many divers. Guests rave about the friendly staff and well-organized logistics, with one reviewer noting how the instructors help improve buoyancy and air consumption.

For about $370.25 per person, this two-day course includes theory, confined water training, and two open-water dives, plus overnight accommodation on Koh Tao.
This course begins on Koh Samui with a theory session, followed by practical confined water training on Koh Tao. You’ll then enjoy your first two open-water dives, where marine life encounters can be spectacular. The course is a good compromise, offering half of the full PADI Open Water Certification and allowing you to enjoy guided dives up to 40 feet afterward. The reviews praise the clarity of instruction and the value of including overnight accommodation and all equipment.
