Boat trips, snorkeling, and dives. Depart from Koror’s harbors and licensed operators.
Rock Islands Southern Lagoon (UNESCO World Heritage)
A 100,200-hectare protected seascape of some 445 mushroom-shaped limestone islets, fringing and patch reefs, and sheltered lagoons immediately south of Koror. Inscribed on the UNESCO list for natural and cultural values, the Rock Islands are experienced by boat with short landings on selected islands for scenic views, snorkeling and visits to protected marine lakes.
Many areas require Rock Islands/Jellyfish Lake permits and guided visits, so plan tours with licensed Koror operators and confirm access rules before travel.

Jellyfish Lake (Ongeim'l Tketau)
Ongeim’l Tketau (Jellyfish Lake) is a scientifically sensitive marine lake noted for endemic, largely stingless golden jellyfish and a strongly stratified water column.
Access is managed by Koror State and typically requires a specific permit and authorised guide; jellyfish densities and lake conditions have fluctuated, and parts of the lake have been temporarily restricted or closed. Verify current permit requirements, closures, and visitor rules with Koror State or licensed operators before planning a visit.

Visitors can see interpretive displays and aquaria, learn about monitoring and restoration work, and join scheduled talks or tours.
Because PICRC is an active research facility, some areas may be closed and advance coordination is recommended for visits.

Ngemelis Islands — Blue Corner & nearby dive sites
Ngemelis, the western cluster of the Rock Islands, contains signature open-ocean wall and current dives such as Blue Corner, Blue Holes and Big Drop-off. Boat-based day dives or liveaboards from Koror deliver steep coral walls, strong tidal currents and abundant pelagics—conditions prized by experienced divers for dramatic drift dives and high photographic value.
Operators match sites to diver certification and may rotate sites to reduce pressure; confirm skill requirements and safety procedures with a licensed Koror operator.

German Channel (famous manta/cleaning-station dive)
German Channel is a man-cut channel that funnels nutrient-rich currents and supports reliable manta-ray cleaning and feeding activity at nearby stations. The site offers shallow to mid-depth reef and sand channels where divers and snorkelers commonly encounter reef mantas; encounters depend on tides and manta behaviour.
Access is by licensed operators from Koror, who enforce approach distances and may limit numbers at cleaning stations.

Ulong Channel (Ngerumekaol) — major dive/wall site
Ngerumekaol (Ulong Channel) is a 500-metre channel and a drift-dive classic west of Ulong Island, known for strong currents, steep drop-offs and dense marine life including trevally, snapper and reef sharks.
Typical visits are boat-based day dives or liveaboard stops from Koror; reef hooks and current techniques are commonly used and operators assign divers by certification and current experience. Confirm conditions, safety requirements and operator rules before booking.

WWII wreck diving sites and related museum/trip departures from Koror
The lagoon and outer reefs around Koror hold a dense collection of World War II ship and aircraft wrecks that combine historical interest with rich reef life. Dives range from shallow lagoon wrecks suitable for intermediate divers to deep or complex wrecks requiring advanced wreck or deep-diving skills.
Koror dive operators run day trips and liveaboards, provide history briefings, and set skill prerequisites; verify wreck accessibility, safety rules and any temporary restrictions with operators and official authorities.
Best Time to Visit Koror
The best time to visit Koror is Palau’s dry season. Roughly November through April.
When rainfall is lower, seas are calmer and visibility for snorkeling and diving is typically clearest. Shoulder months (late April–May and October) can offer good diving with fewer tourists.
Expect sudden showers year-round and allow flexibility for weather-related changes when booking liveaboards or guided excursions.
Getting Around Koror
Koror is compact and most logistics are water- or road-based. Domestic flights and ferries connect to nearby islands, but Rock Islands access requires booked boat charters, dive operators, or guided day trips from Koror’s harbors.
Within town, short taxi rides, tuk-tuks and rental scooters are common; walking works well in the central district. When island-hopping or diving, confirm operator pickup points, boat safety certificates, and any national-park permits.

Safety
Follow Koror State marine and conservation rules: many Rock Islands areas require permits and licensed guides, and entering closed marine lakes can carry fines. Ocean conditions include strong currents at channels and dive sites, sharp coral, and sudden weather changes—use licensed boat operators, heed briefings, and meet dive-skill requirements.
Protect against sun exposure and limited fresh water on small boats. For sensitive sites like Jellyfish Lake, follow guidance to avoid disturbing wildlife and check for temporary closures.
