Think you’ve seen everything Belitung has to offer? Think again. Put away the beach towel for a second and grab your hiking shoes, because Open Pit Nam Salu is about to flip your perspective on what a “tropical island” looks like.
Located in Kelapa Kampit, East Belitung, this isn’t your typical palm-fringed paradise. It is a raw, rugged, and breathtaking UNESCO Global Geopark site that looks less like Indonesia and more like a colony on the Red Planet.
Open Pit Nam Salu was once the largest and deepest open-pit tin mine in Southeast Asia. Today, the machines are gone, and nature has reclaimed the site in the most spectacular way.
The Crater: As you reach the viewpoint, the earth opens up into a massive, jagged amphitheater of deep red and ochre rocks. At the very bottom sits a mysterious, mirror-still lake with water so deep blue it looks like a fallen piece of the sky.
The Tunnels: This is the “hidden” adventure. You can actually walk through the old mining tunnels. It’s cool, dark, and a little bit eerie—the perfect contrast to the tropical heat outside. It’s like stepping back into the 19th-century mining glory days of Belitung.
If you’re a photographer or just someone who loves a “grid-worthy” shot, this place is a goldmine (or a tin-mine, literally).
The contrast between the crimson cliffs, the emerald greenery, and the cobalt water is unlike anything else in the archipelago.
Pro Tip: Wear something white or bright yellow. The pop of color against the deep red earth makes for an epic, cinematic photo.
Nam Salu isn’t just about the views; it’s a geological miracle. The rocks here date back hundreds of millions of years. Walking through the site is like reading a history book written in stone. It tells the story of how Belitung was formed and how its “Blue Gold” (tin) shaped the island’s destiny.
Once you’ve conquered the pit, head back down to the town of Kelapa Kampit or Manggar. Do as the locals do: find a small coffee shop, order a Kopi Susu Peng, and talk about the trek. The narrative of East Belitung is one of resilience and transformation, and you can feel it here more than anywhere else.
Difficulty: It’s a bit of a hike, so a basic level of fitness is good.
What to Wear: Sturdy sneakers or hiking boots (the terrain is rocky and can be slippery) and plenty of sunscreen.
Local Legend: Ask your guide about the history of the “Stannum” and how the miners used to work these deep veins of tin.
