Leave all the conveniences of the modern
 world behind, cross the strait between concrete structures and 
extraordinary woods, venture into a world of natural splendor, and gaze 
upon some of the most mystifying sceneries on the face of the earth : 
 those are what  the secluded Sempu Island has to offer.
Situated on the south coast of Malang 
Regency in East Java and administratively located in the Tambak Rejo 
Village, Sumbermanjing Wetan Sub-District, this small island lies just 
off the coast of 
Sendang Biru Beach, approximately 80 Km from 
Malang city or about 180 Km from the capital of East Java, 
Surabaya.
 The 877 hectares forested island is a Nature Reserve under the 
management of the Natural Resources Conservation Office of East Java 
(BBKSDA) and the Ministry of Forestry of Indonesia, and was actually 
designated a Nature Reserve since 1928 in the Dutch Colonial period.
 
Among the island’s most fascinating features is the Segara Anakan lagoon
 located about 2.5Km further south into the island. Hidden deep beyond 
the thick tropical forest, the approximately 4 hectares lagoon is truly a
 secluded paradise where a white sandy beach meets calm blue waters 
separated from the raging tides of the open ocean by a picturesque rocky
 wall surrounding the area. The incoming tides penetrate only through 
several caves above and below the surface, thus the water inside the 
lagoon remains calm, and makes a perfect place for swimming. Its 
secluded location also radiates a sense of intimacy, where the beach 
becomes a private getaway, not unlike the setting for the 2000 Leonardo 
Di Caprio’s Movie “The Beach”.

Adventure
 awaits  those who wish to explore Sempu Island and reach the Segara 
Anakan Lagoon. Cross the straits from Sendang Biru Beach on the mainland
 to the 
Teluk Semut (Ant Bay) at Sempu Island.
 From here, the journey continues over a trekking path for about two 
hours through quite thick forest with several ascending and descending 
tracks,  before one reaches the secluded lagoon. While the trip may not 
be an easy walk, the grand price that awaits at the finish line is more 
than just worth it. Boats and guide services are available at the 
Sendang Biru Beach area.
 
Sempu Island also has other fascinating spots which offer equal splendors including the Waru-waru beach, Telaga Lele (Catfish Lake, a fresh water lake named after the many catfish found within), Tiger Cave,  Pasir Panjang Beach (Long sand Beach), Pasir Kembar Beach (Twin sands beach), Fresh Water Beach (named after a fresh water spring on the rocks near the beach), and Telaga Sat (Dry Lake).
As a Nature Reserve, Sempu Island has 
various types of ecosystems  ranging from coastal forest, mangroves, and
 lowland tropical forest which dominates the whole island. Among the 
vegetation found on Sempu Island are bendo (Artocarpus elasticus), 
triwulan (Terminalia), wadang (Pterocarpus javanicus), ketapang 
(Terminalia catappa), waru laut (Hibiscus tiliaceus), pandan (Pandanus 
tectorius), Mangroves (Rhizophora mucronata and Rhizophora apiculata),
 and many more. Interestingly, the name Sempu is said to have been taken
 from a particular type of tree that is found in the island, however, 
the tree can hardly be found these days.
The Nature Reserve is also home to several wildlife inhabitants such as:  the Javanese Monkey (Tracypithecus auratus), Black Monkeys (Presbitis cristata pyrrha) , Grey Macaques  (Macaca fascicularis), wild boar (Sus sp), deer (Muntiacus muntjak), kancil/small deer (Tragulus javanicus), Prawn (Alcedo athis), belodok fish (Periopthalmus sp), crab (Ocypoda stimsoni),
 and many more. There are also several types of reptiles including giant
 lizards and snakes and also several types of birds that find shelter on
 the island.
