Trekking Mount Tambora: A Once-in-a-Lifetime Experience

The hike to the rim of Tambora’s caldera is physically demanding but not technically difficult, making it accessible for most trekkkers. The trail is well-maintained and solid, requiring no climbing skills.

For many years, we have guided guests on Mount Tambora and continuously work to provide the best possible trekking experience. During peak periods such as public holidays and school breaks, the mountain can become busier, especially around the public campsites. Most of the recent growth in visitor numbers comes from domestic hikers, including local school and student groups, while international tourism to Mount Tambora remains relatively small, with only approximately 100 to 200 foreign visitors annually.

In the meantime, we continue to carefully organize our trips to avoid the busiest periods whenever possible and to ensure our guests enjoy a safe, comfortable, and memorable journey on one of Indonesia’s most spectacular volcanoes.

Despite the increasing number of visitors, Tambora remains an extraordinary destination, offering dramatic landscapes, unforgettable sunsets, and the unique experience of standing on the rim of the world’s largest volcanic caldera.

Tambora National Park is usually closed during the rainy season, which runs from December to April. In 2025 and in 2026, however, the closure was extended until mid-May.

As a result, our tours will start on May 15th and operate until October 15th.
