[3] Karimun Java is also a tourist attraction popular for its white sandy beach, pristine coral reefs, challenging treks through the hills, the pilgrimage to Sunan Nyamplungan Cemetery, and the customs and traditions of the Karimunjava community.

Historical Sources relate the discovery of the Archipelago by Chinese Army sent by emperor Kubhilai Khan in 1293 (they named it CHI-LI-MEN), followed by Ottoman Turkish navigators in 1403, Portuguese, Dutch, French (Bouguinville ...), English etc ...

Many Yachtmen continue the tradition and stop now in Karimunjawa on their way from Australia to Thailand or China sea or back ...

[4] The topography of Karimunjawa Marine National Park is a wave of low land, with elevation ranging from 0–506 meters above sea level.

Many researchers have been attracted to the marine biodiversity and pristine forest as well as the uniqueness of the Karimunjawa archipelago.

Other protected sea biota include the hornet helmet (Cassis cornuta), triton trumpet (Charonia tritonis), chambered nautilus, green shell (Turbo marmoratus), and six species of clam.

The seaweed species are grouped into three divisions: Chlorophyta (Coulerpa and Halimeda), Phaeophyta (Padina, Sargassum and Turbinaria) and Rhodophyta (Eucheuma, Gracilaria, Gelidium, Hypnea and Acanthopora).

It provides habitat to a number of endemic species including the mythical dewadaru tree (Fagraea elliptica), setigi (Pemphis acidula) and kalimasada (Cordia subcordata).

It is generally believed that the wood of the endemic dewadaru tree has a legendary power of curing diseases or snake bite wounds, protecting house from thieves, or prolonging life.

[3] There are about forty different bird species in the island, including the green imperial-pigeon, (Ducula aenea), yellow-vented bulbul (Pycnonotus goiavier) and red-breasted parakeet (Psittacula alexandri).

The lowland tropical rain forest is the natural habitat of the rare white-bellied sea eagle.

However, it is still possible to see Javan rusa deer (Cervus timorensis), Sunda pangolin (Manis javanica), and the Malayan pit viper (Calloselasma rhodostoma).

Karimunjawa community consists of many ethnic groups such as Javanese, Madurese, Bugis, Mandar, Bajak, and Luwu.

So one day Sunan Muria drove his son away from home with the warning that he was not to set foot on Java again.

In sadness, the son left Mount Muria where they dwelt and moved on to the open seas to the north.

He sailed on a boat for many days through stormy weather and amidst huge waves, not really knowing his destination and perhaps with little will to survive.

Meanwhile, from the peak of Mount Muria in Java, the boy's father was secretly watching over his son clairvoyantly.

One hardly finds the villagers using this wood for the fashioning of furniture or as a building material; and only the courageous would use it in their spiritual activities.

But it is also believed that Sunan Nyamplungan, the guardian of the island, or his proxy, plays a role in protecting the place from pilferers.

[10] In 1992, the faculty of biology of the University of Gajah Mada conducted some research on the Dewadaru and the report of their analysis states that this tree is quite rare and not easily propagated.

Menjangan Kecil, Menjangan Besar, Tanjung Gelam, Legon Lele, Genting, Kembar, Parang, Cemara and Krakal Islands are popular marine tourism destinations (sailing, surfing, swimming, white sand beaches, diving), camping, cultural visits, and bird observation.
