Indonesia, with its more than 17,000 islands and nearly 81,000 kilometers of coastline, holds countless remote and wild beaches untouched by mass tourism. As part of our Nature Adventures category, this article invites you to explore a different side of Indonesia’s coastal beauty — unspoiled beaches that offer exploratory, cultural, and ecological depth.

West Sumba’s Rugged Coast
Watu Maladong: Sea Rock Formations and Marapu Traditions
Located on the western coast of Sumba Island, Watu Maladong is known for its fortress-like sea rock formations. Surrounded by savannah and limestone cliffs, it’s an ideal destination for light trekking and landscape photography. The nearby villages still practice the Marapu belief system, offering visitors a unique opportunity to understand ancestral traditions and their harmonious relationship with nature.
Kei Islands: Trekking Through Time and Tide
Pasir Panjang and the Mangrove Trails
Pasir Panjang, a beach on Kei Kecil Island in Southeast Maluku, features over three kilometers of soft white sand. Beyond swimming and sunbathing, visitors can hike through mangrove trails or explore natural caves such as Goa Hawang. A global study found that mangrove, seagrass, and coral reef ecosystems combined protect coastlines more effectively than each habitat on its own (Guannel et al., 2016, PLOS ONE).
Interacting with local communities, such as the traditional village of Ngilngof, also provides insight into how indigenous knowledge supports sustainable coastal management.
Karimunjawa: Snorkeling and Marine Conservation
Ecological Recreation in the Karimunjawa Islands
Karimunjawa is a marine national park that protects coral reefs and endangered species such as green turtles. Snorkeling and diving here become educational activities that raise awareness about the importance of shallow marine ecosystems. Community-led programs for coral restoration and turtle conservation further establish Karimunjawa as a model for sustainable ecotourism.

Buru Island: Silence and Biodiversity
Birdwatching and Kayaking Along the Bay
Buru Island in the Maluku region offers pristine coastal experiences far from tourist crowds. The mangrove-lined Kayeli Bay provides opportunities for relaxed kayaking and birdwatching, with chances to spot endemic species such as the Buru white-eye. The surrounding ecosystems are highly biodiverse and underscore the importance of local conservation.
Science and Conservation: Foundations for Sustainability
Blue Carbon from Mangroves in Negeri Waai, Central Maluku
A 2024 study assessed the blue carbon potential of mangroves on Negeri Waai’s coast, estimating approximately 73.22 t C/ha total carbon stock—49.44 t C/ha above-ground and 23.78 t C/ha below-ground (Rahman et al., 2024, Jurnal Ilmu Kehutanan).
Ecotourism and Behavioral Change
Educational and participatory ecotourism—including community-based coral and turtle programs—can foster environmental awareness and strengthen community livelihoods while preserving coastal ecosystems.
