About Koror

Koror is the practical base for most Palau journeys, but its strongest experiences extend beyond the urban streets. The city provides accommodation, food, cultural and historical stops, dive operators, and access to the protected Rock Islands Southern Lagoon; Babeldaob adds a different inland landscape across the bridge. Use registered guides and confirm the required permits before entering marine areas, because conservation rules are part of the destination rather than an optional extra. Weather, boat capacity, and visibility can change the order of a day, so keep marine plans flexible.
