Bukit Lawang Orangutan Trek: Complete Guide to Gunung Leuser
Trek Gunung Leuser National Park from Bukit Lawang to see wild orangutans, gibbons, and hornbills. Costs, guides, and what to expect.
Trekking
Indonesia sits on the Pacific Ring of Fire — the archipelago has more active volcanoes than any other country on earth. Trekking up these volcanoes is one of the most compelling experiences in Southeast Asia: pre-dawn crater climbs on Bromo, the blue sulphuric fire of Kawah Ijen, and the crater lake summit of Rinjani on Lombok are in a different league from most hikes in the region.
Most volcano treks require a licensed local guide — both for safety (gases, terrain) and legal reasons (many sites mandate it). Guides are arranged through operators in the nearest town. Rinjani requires a 2–3 day commitment with camping; Bromo and Ijen are accessible in a single pre-dawn excursion. Batur on Bali is the most accessible option for a half-day sunrise trek.
Indonesia's best volcano hikes and trekking routes — from half-day sunrise climbs to multi-day expeditions.
