Karimunjawa is an archipelago of 27 small islands scattered in the Java Sea off Jepara, where clear water, coral reefs, and white-sand beaches feel a world away from the traffic and density of Java just a short ferry ride south. Most of the islands are uninhabited and protected as a national marine park, making this one of the few easily reached spots in Java for snorkelling with reef fish, sharks at a conservation pool, and genuinely quiet beaches.

Traveler reviews

★★★★☆

Hard to believe this is just off the coast of busy Java — clear water, quiet beaches, and great snorkelling on the day-trip islands. The ferry crossing was a bit rough but worth it.

Bayu W. · June 2024

★★★★☆

A relaxed few days island-hopping by boat, with empty beaches at most stops. The shark pool was a fun add-on and the seafood in the evenings was excellent value.

Sophie L. · August 2023

★★★☆☆

Good value and a real escape from Java's crowds, though infrastructure is fairly basic — go with relaxed expectations and it's a lovely few days.
