Kalimantan is a paradise for adventure seekers. With its dense rainforests, winding rivers, sprawling wetlands and diverse wildlife, it offers a unique experience for those looking for Borneo off the beaten track. It occupies 2/3rds of the island of Borneo, yet is by far the least visited area. It’s Muslim cities with their grand mosques give way to the Dayaks in their longhouses, this is by far the best area of Borneo to experience Dayak culture. Kalimantan mainly hits the headlines for its worrying and swift deforestation for development and oil palm plantations and the destruction can be seen on any long drive in the region, however it still has the largest forest blocks in Borneo. It has the world’s largest Orangutan populations by far, which can be found on foot, staying in ranger stations or from a klotok, a traditional floating house boat. It’s forest reserves and national parks are still humming with biodiversity and are rarely visited apart from Tanjung Puting, of which we have designed a special trip designed to steer clear of the crowds and also focus on some of the rarer wildlife of the park. Other areas are far more private with many rare primates, chances at elusive nocturnal creatures and a whole suite of tropical birdlife. Whilst birding here is nowhere near as popular as neighbouring Sabah, there are some species here that are easier to see here or indeed found nowhere else. In 2020 the Black-browed Wren Babbler was rediscovered in the Meratus Mountains after a hiatus of 180 years and since then other species have been found to be endemic to the range. Many Sundaic wetland specialists are also easiest to see here, and rarities such as Bornean Peacock Pheasant, Crestless Fireback, Bornean Bristlehead & many pittas have been recorded in easy to access forested areas. Adventure birding is possible too with many areas under-surveyed, and unique journeys, such as hornbill conservation trips with the locals in Sungai Utik. Offshore are the islands of Maratua & the Derawan archipelago. Here the jungled hills and wetlands are replaced with white sand beaches, limestone caves, saltwater lakes filled with stingless jellyfish & vibrant coral reefs. Turtles are everywhere here, with spots for diving with manta rays and whale sharks. Please view the overview for destinations we visit in Kalimantan & our suggested itineraries below.
