About this tour
Two dives for certified advanced divers exploring Tangked and Biaha Shark Caves in Bali's Northeast waters. Descend to 26m and 12m respectively to encounter whitetip reef sharks and marbled whiprays in their natural habitat. The 9-hour excursion departs Sanur at dawn, involves a 60-minute minivan ride and 30-minute traditional boat journey to reach these challenging sites. Strong currents demand experience; July–October offers bonus sightings of mola mola. All kit, meals and transport included.
Highlights
- Whitetip reef sharks and marbled whiprays in cave systems
- Depths of 26m and 12m across two distinct sites
- Mola mola sightings likely mid-year
- 1:4 dive leader ratio for safety and guidance
- Optional third dive at Gili Tepekong or Gili Mimpang
- Traditional jukung boat from Padangbai village
What to expect
Expect an early start from your hotel at 7am, followed by a minivan journey to Padangbai where you'll board a wooden jukung for the final approach. Tangked demands respect—currents are strong and unpredictable, so only seasoned divers should attempt it. Biaha is more forgiving. Both caves reward patience: sharks patrol regularly, whiprays glide overhead, and the rock formations themselves command attention. You'll surface by early afternoon, rinse off on the boat, and return to your hotel around 4–5pm. Lunch and unlimited water sustain you throughout.
Good to know
PADI certification and medical clearance required before arrival. Bring your medical form completed and signed by your doctor if you've answered yes to any questions. Currents at Tangked suit experienced divers only. Not suitable if pregnant, with spinal injuries, or significant cardiovascular concerns. Minibus is air-conditioned with WiFi. Reef shoes and sun protection essential.
