Borneo Eco Adventure

Borneo Eco Adventure is a Kalimantan-based tour operator headquartered in Balikpapan, East Kalimantan, that handles birding, wildlife and adventure trips throughout Indonesian Borneo. The company has built itself around the logistical problem of getting birders into a set of widely spaced Kalimantan sites — Tanjung Puting, Kutai, Sungai Wain, Mahakam River, Meratus and Maratua — that are difficult to reach without a local fixer. Their headline birding programs include multi-day Kalimantan endemics circuits and tours specifically targeting the Black-browed Babbler, which was rediscovered in South Kalimantan in 2020 after a 170-year absence from records. Itineraries also typically include orangutan viewing and other Bornean megafauna alongside the bird list. The outfit is small and locally run, the kind of regional ground operator international birding companies tend to subcontract for the Kalimantan leg of pan-Borneo itineraries.
