Segara Anak Crater Lake

Danau Segara Anak

Segara Anak is a freshwater crater lake nestled within Mount Rinjani's caldera at 2,000 meters elevation, surrounded by dramatic volcanic walls and accessible only by trekking. The ethereal alpine lake represents one of Lombok's most remote and spiritually significant natural features, rewarding effort with unforgettable views.

Things to do

• Summit Trek to Mount Rinjani Peak — Push beyond Segara Anak to reach Rinjani's 3,726-meter summit for panoramic views across Lombok and neighboring islands at sunrise.
• Hot Spring Bath at Aiq Kalak — Soak in natural hot springs located near the crater lake's shore, fed by geothermal activity within the caldera.
• Freshwater Swimming — Wade and swim in the clear, cool alpine waters of Segara Anak itself, a rare freshwater lake experience in volcanic terrain.
• Photography and Sunrise Viewing — Capture the ethereal alpine landscape during golden hour when volcanic walls glow and mist rises from the crater floor.
• Spiritual Meditation and Prayer — Honor the lake's sacred significance to local Sasak communities by participating in quiet contemplation or respectful ceremonial observation.
• Flora and Fauna Observation — Spot endemic alpine plants, birds of prey, and occasionally sambar deer that inhabit Rinjani's high-altitude ecosystem.

Food to try

• Nasi Kuning (Yellow Rice) — Turmeric-infused rice cooked in coconut milk, commonly prepared at porter camps as a staple carbohydrate source during the trek.
• Ayam Betutu — Slow-cooked chicken wrapped in banana leaves with aromatic spices, a traditional Balinese-Sasak dish sometimes available at base camps.
• Gado-Gado — Mixed vegetable salad with peanut sauce, lightweight and protein-rich, frequently served at trekking camps for vegetarian trekkers.
• Lombok Coffee (Kopi Lombok) — Strong, locally-grown coffee served hot to warm trekkers at dawn, cultivated on Lombok's volcanic slopes.
• Instant Noodles with Local Vegetables — Simple but effective trail food prepared at camp with foraged local greens and eggs, sustaining for high-altitude hiking.

Local customs & good to know

• Respect Sacred Offerings — You may encounter small offerings (flowers, incense) left by Sasak pilgrims; treat these with reverence and do not disturb them.
• Hire Local Guides and Porters — Supporting Sasak guides and porters is culturally important and economically vital; they possess invaluable knowledge of safe routes and spiritual significance.
• Dress Modestly at Base Camps — Though trekking in functional gear is acceptable, avoid revealing clothing around porter communities and villages to show cultural respect.
• Ask Permission Before Photographing People — Local porters and villagers may not wish to be photographed; always ask politely and offer respect for their wishes.
