Founded in 1817 by the Dutch East Indies Company, in collaboration with experts from Kew, the Bogor Botanical Gardens holds one of the world’s greatest collections of tropical plants: 3,373 species are represented, including around 500 different kinds of orchids and 288 rare palms, lining beautifully mown lawns and avenues of stately trees. The vast, state-owned Gunung Mas tea plantation lies at the heart of the Puncak hill region – a favourite weekend getaway for Jakartans, who love its fresh, clean air and vistas of lush tea terraces. The plantation offers the ideal place to break the journey from JK to Bandung.

Java’s second city, Bandung, lies 118 miles (190km) southeast of Jakarta. Known for its colonial-era Art-Deco architecture, it enjoys a spectacular setting at the foot of Tangkuban Prahu, a dormant volcano whose summit may be reached via an enjoyable hike, or by road. After scaling the mountain, you’ll have the chance to bathe in the hot springs of Sari Ater. Traditional Sundanese music, dance and puppetry take centre stage at Saung Angklung Udjo arts centre, where you’ll be able to attend a performance in the evening. Proceeds fun the training at the centre for students from disadvantaged backgrounds.

Tiny Cankuang Lake nestles amid paddy fields in central Java, surrounded by four huge dormant volcanos. In 1996, a wooded islet on it was found to hold a ruined Hindu temple, which forms the focal point of visits. You can also wander around the nearby village to see its colourfully painted Javanese houses. Even more traditional in appearance are the 108 bamboo and thatch dwellings at Naga, enfolded by sacred forest in an oxbow of the Ciwulan River. Reached via a flight of 300 steps, the settlement is something of a ‘land that time forgot’, with no electricity or cars.

The Dieng Plateau is a lush, cloud-swept caldera at an altitude of 2,000m (6,600ft). Encircled by dramatic volcanic peaks, the steep sides of the crater are sculpted with twisting terraces of potato and cabbages. Over one-thousand years ago, the floor of the plateau was carpeted with tiny Hindu temples, of which a scattering survive. Whether gilded by the early morning sunlight or wreathed in mist, they’re a beautiful sight.

Yogyakarta, where you’ll arrive in the evening, is Java’s culture capital, and the best base for visits to the ancient sites of Borobudur and Prambanan.

Dedicated to the Hindu god Shiva, the UNESCO-listed Prambanan complex centres on an elaborately carved, 47-metre-tall sanctuary tower, surrounded by over 200 subsidiary shrines, all of them richly decorated. The spectacle of this extraordinary behemoth soaring above the palm canopy, ranks among the most memorable Southeast Asia has to offer. No less exotic are the ruins of ancient Borobudur. At sunset you can watch the warm evening light illuminating the faces of 1200-year old stone Buddhas, which gaze over a plateau of rice fields and palm groves to the plume of smoke rising from the summit of Gunung Merapi.

Surakarta is Java’s second royal capital. It was established in the mid-18th century and continues to be an important hub of Javanese culture. Music (particularly gamelan) and traditional courtly dance is still widely studied and performed here, but the great local speciality is batik. Some of the finest textiles in all Indonesia originate in the city, and you can admire superb antique pieces in the famous Danar Hadi museum. Two kraton palaces survive, dating from the years after 1745 when European power was in the ascendency.

Skirting the feet of two formidable volcano mountains Gunung Lawu and Gunung Ngliman – the onward drive to Kediri is outstandingly scenic.

For Javanese people, the finest and most expensive of all coffees is ‘kopi luwak’, a brew made with a bean extracted from the faeces of the Asian palm civet. It is believed that something in the fermentation process occuring as the beans move through the civet’s gut enhances the flavour. You can decide for yourself whether there’s anything in the tale when you visit a farm where kopi luwak is produced. Surrounded by four magnificent volcanoes, Malang ranks among the world’s most dramatically sited cities. It’s worth finding time to explore the faded old town, established by the Dutch in the late-18th century on the back of the coffee trade.

Peaking at 2,392m (7848ft), Gunung Bromo may not be Indonesia’s highest volcano, but it’s one of the most conveniently accessible, with a road running all the way up to the lip of the caldera’s encircling cliff, from where the views are magnificent. Bromo is actually one of three volcanoes cradled in a massive, 10-kilometre crater that’s carpeted in a covering of grey-brown sand and ash. Rising in the background, a plume of smoke and steam billows from the perfectly symmetrical snout of Gunung Semeru, Java’s loftiest peak (3,676m / 12,000ft) – surely one of the most extraordinary views in the world!
