At the westernmost tip of Java, along the Sunda Strait, Ujung Kulon National Park harbors the last wild population of Javanese rhinoceroses. Across its 1,200 km² of forests, mangroves and grasslands, some fifty individuals of this herbivore live—among the most threatened species on the planet. The park, inscribed on the UNESCO World Heritage List, also encompasses the Ujung Kulon peninsula and the natural reserve of Krakatoa volcano.

Why visit Ujung Kulon National Park

Ujung Kulon is above all a scientific sanctuary. Here, and nowhere else in the world, survives the Rhinoceros sondaicus, the Indonesian subspecies of the Javanese rhinoceros. The two other historical subspecies, Indian and Vietnamese, became extinct during the twentieth century.

Beyond this flagship species, the reserve protects wild banteng cattle, Javanese deer, silvery gibbons, leopards, dolphins at sea, and more than 250 bird species. The canopy density and geographic isolation make it one of the last great lowland forest ecosystems in Java.

Let's be clear: spotting a rhinoceros is the exception rather than the rule. The animal is solitary, wary, equipped with highly developed senses of smell and hearing that compensate for poor vision. Visitors come mainly for trekking through primary forest, birdwatching, and excursions to Krakatoa volcano.

What to see and do in the park

The Ujung Kulon Peninsula

The heart of the park is explored on guided hikes, typically lasting two to four days. The trails traverse humid tropical forests, skirt deserted beaches, and pass near waterholes where rangers regularly spot rhinoceros footprints. Nights are spent in bivouac or ranger posts.

Peucang Island

A small island off the peninsula, Peucang often serves as a logistical base. Clear waters suited to snorkeling, rustic lodges, and abundant sightings of deer, monitor lizards and macaques: it is a comfortable stopover before more demanding treks on the mainland.

The Krakatoa Reserve

North of the park, Anak Krakatau ("the child of Krakatoa") continues its eruptive activity since 1927. Boat excursions from Carita or Anyer allow you to approach the archipelago, sometimes stepping foot on still-warm ashes depending on current volcanic activity and regulations in effect.

The Javanese Rhinoceros at a Glance

• Herbivore: fruit, shoots, leaves and bark
• Size: 2 to 4 m long, 1.4 to 1.7 m at the shoulder
• Single horn, unlike other Asian rhinoceroses
• Life expectancy: 30 to 45 years
• Gestation of 16 months; the calf stays with its mother for 3 years
• Maturity at 4 years (females), 6 years (males); breeding every 4 to 5 years

Practical Information

Access Permits

Entry to the park requires a permit issued by national park authorities. Procedures are handled in Labuhan or directly at registration posts in Sumur and Tamanjaya. Bring your passport and a copy. Entry fees are moderate but vary depending on nationality and length of stay.

Mandatory Guide

Visits must be conducted with a certified ranger or guide accompanying you on the trails. This is both a regulatory requirement and a safety guarantee, as the jungle is dense and encounters with wildlife—snakes, monitor lizards, wild boar—are possible.

Accommodation

Three main options: lodges on Peucang Island, village guesthouses in Tamanjaya, or bivouacking with your guide for longer itineraries. Comfort remains basic; come equipped with rain gear, closed-toe hiking shoes and insect repellent.

Duration of Visit

Plan for a minimum of two days for a thorough exploration, ideally three to four to combine the peninsula and Krakatoa. A simple day visit from Jakarta makes little sense given travel times.

When to Go

The dry season, from April to October, is clearly preferable. Trails are passable, boat crossings safer, and sea visibility better for Krakatoa excursions. The rainy season (November-March) makes many trails impassable and some operators suspend their trips.

How to Get There

The park is located approximately 200 km west of Jakarta, but access remains challenging. From Jakarta, plan for 5 to 7 hours of driving to reach Labuhan or Tamanjaya. From there, entry to the park is mandatory by boat departing from Sumur or Tamanjaya, with one to three hours of navigation depending on the destination (Peucang, Handeuleum or the peninsula coast).

Many travelers use a local agency that handles transportation, permits, guides and accommodation as a package—this is generally the simplest solution given the logistical complexity.

What to See in the Region

The return to Jakarta can be enriched by several stops:

• Anyer and Carita: seaside resorts on the west coast, alternative departure points for Krakatoa
• Banten: former capital of the sultanate, historical remains and colonial architecture
• Bogor: its famous botanical garden, on the road to Jakarta

Travelers extending their stay eastward often head toward Bali and the Komodo Islands or the nearby Rinca Island, other major Indonesian wildlife destinations.
