Different water, different diving

South Komodo sits where the Indian Ocean meets the Flores Sea. The water is cooler, the currents are stronger, and the topography drops further. That mix brings in pelagics, feeds dense reefs, and creates the kind of dramatic underwater landscapes you don’t see in the north of the park. We dive the south on full-day trips when conditions allow, and on multi-day liveaboard itineraries aboard Maria Seascape.

These are advanced sites. Most require Advanced Open Water and solid drift skills. We brief every site every morning, and we’ll only run them when the tide and weather agree.

Best months and what to expect

South Komodo conditions vary more by month than the north. April to September is the prime window — calmer surface conditions, clearer water, and the cooler currents that bring in pelagics. October to March is rainier and choppier; we still dive the south on calm days.

Water in the south runs cooler — often 24–26°C, sometimes down to 22°C around Nusa Kode in the dry season. Bring a 5mm wetsuit, or a 3mm with a hooded vest if you feel the cold.

German Flag

Named for a German flag placed here years ago. Shallow reef with excellent macro life. A relaxed alternative to the bigger sites. Good for a third dive or when other conditions are too rough.

Marine life :

  • Nudibranchs
  • Ghost pipefish
  • Seahorse
  • Frogfish
  • Decorated dartfish
  • Reef fish

Tips:

Best in morning light. Works well as a final dive on a south route day. Calm and suitable for all levels.

November – March

Langkoi

A sheltered bay on the south coast with mixed reef and sand habitat. Good macro life and occasional turtles. Used as a surface interval spot or relaxed second dive base when running south routes. Provides good protection from swells.

Marine life :

  • Turtles
  • Ribbon eels
  • Nudibranch
  • Blue-spotted stingray
  • Reef fish

Tips:

Useful for shelter and surface intervals on south route days. Good fallback when other south sites are too rough.

Three Sisters

Three submerged pinnacles in a row in the southern region. Good soft coral coverage and fish action. Each pinnacle has its own character — the southernmost is deepest and has the best pelagic activity. Less visited than Crystal/Castle.

Marine life :

  • Schooling fish
  • Soft corals
  • Grey reef sharks
  • Napoleon wrasse
  • Sea fans
  • Hammerhead (occasional)

Tips:

Dive the three in sequence with current. The easternmost pinnacle has the best coral. Strong current can arrive quickly.

Recommended season :

November – March

Depth

5–30 m

Current

Moderate to strong

Visibility

10–22 m

Water Temp

26–29°C

Type

Level

Intermediate–Advanced

Pilarsteen

A cluster of submerged rock formations creating channels and swim-throughs. Good fish concentration around the structure. Interesting topography with crevices, overhangs, and passages. Occasional hammerhead sightings on the deeper sections.

Marine life :

  • Rock formations / swim-throughs
  • Schooling fish
  • Reef sharks
  • Hammerheads (occasional)
  • Lobster
  • Moray eels

Tips:

Explore the channels between the pillars — they hold the most life. Current can be tricky between formations. Good reef hook site.

Recommended season :

November – March

Depth

5–30 m

Current

Moderate to strong

Visibility

10–20 m

Water Temp

26–29°C

Type

Manta Alley

A channel site in the south known for consistent manta ray activity during the south season. Multiple cleaning stations along a sloping reef. Mantas cruise the channel regularly — sometimes several at once. One of the best dedicated manta sites in the park.

Marine life :

  • Reef manta rays
  • Multiple mantas simultaneously
  • Cleaning station behavior
  • Eagle rays
  • Reef fish

Tips:

Position yourself at a cleaning station and stay low and still. Nov–Mar is peak season here. Wetsuits essential — cold upwelling common. Avoid chasing or approaching mantas from above.

Recommended season :

November – March

Depth

3–25 m

Nusa Kode

Remote island complex at the far south of Komodo NP — 1.5–2 hrs from Labuan Bajo. Multiple dive sites around the island: walls, pinnacles, manta cleaning stations, and some of the strongest currents in the park. Cold water upwelling is intense — water can drop to 20°C. Rewards are exceptional: manta aggregations, schooling hammerheads, occasional whale sharks, and pristine deep walls. South swell during this season means sea state must be checked carefully. Liveaboard or dedicated long day trip only.

Marine life :

  • Manta ray aggregations
  • Schooling hammerheads
  • Whale shark (occasional)
  • Pristine deep wall
  • Extreme cold upwelling
  • Remote / very low traffic

Tips:

Liveaboard or dedicated early-start long day trip only. 3–5mm wetsuit, hood recommended. Check sea conditions the night before — south swell builds fast. Allow 3–4 dives across different parts of the island for the full experience.

Recommended season :

November – March

5–40 m

Multi-day liveaboard aboard Maria Seascape. The right way to dive the deep south — Pillarsteen, Three Sisters, Manta Alley, and Nusa Kode in one trip, without the long boat rides each morning. See itineraries on the Maria Seascape page
