Journeys
Arasatu is surrounded by some of East Kalimantan’s most remarkable natural destinations — hidden caves, crystal lakes, rare marine encounters, and quiet islands with turquoise water.
Our journeys are crafted to be calm, respectful, and unhurried.
Curated explorations across the Derawan Sea
Goa Halo Tabung — The Hidden Tube Cave
A long, narrow sea cave shaped by centuries of water and light.
Inside, soft reflections illuminate the sandstone walls, creating an atmosphere that feels ancient and cinematic.
Quiet, echoing, and unlike anything else in the region.
This is the signature wonder of Maratua.


Kakaban Island — The Jellyfish Sanctuary
A world-renowned natural lake filled with non-stinging jellyfish drifting gently beneath the surface.
Swimming here is silent and surreal — a calm, dreamlike moment surrounded by golden movement and clear water.
A rare ecosystem found in only a few places on Earth.


Kehe Daeng — The Hidden Blue Pool
A secluded saltwater chamber tucked inside the forest.
The pool glows in deep blue, still and clear, surrounded by rock walls and quiet air.
A serene, almost sacred spot — perfect for a slow swim and quiet reflection.
A peaceful escape hidden away from the open sea.
Sangalaki Island — Mantas, Turtles & Clear Water
A protected island known for gentle wildlife encounters.
Glide above coral gardens, swim alongside sea turtles, and, when the season aligns, witness mantas moving in slow arcs.
Warm, open, and full of life.
Derawan Island — Village, Reefs & Island Culture
An island rich with colour and community — floating houses, soft reefs, and friendly coastal life.
Explore village paths, snorkel in bright shallows, or drift along the coastline in warm afternoon light.
A gentle mix of culture and sea.


Talisayan Whaleshark Point
A rare early-morning encounter with whalesharks — enormous, peaceful, and slow-moving.
Their presence is humbling and quiet, offering one of the most meaningful wildlife moments in the region.
A respectful approach and timing are essential.


Labuan Cermin — The Two-Layered Crystal Lake
A stunning natural phenomenon where saltwater and freshwater never mix, creating two perfectly clear layers beneath a glasslike surface.
The water is so transparent it feels as if boats float on air.
Silent, bright, and extraordinary.


Manimbora — The ‘SpongeBob’ Sand Island
A small, bright sandbank surrounded by turquoise water.
Empty, calm, and beautifully simple — the perfect place for quiet moments and effortless photos.
Time feels slower here.
