About Air Terjun Tanah Merah

• Location: Samarinda, East Kalimantan, Indonesia
• Coordinates: -0.433329, 117.233730
• Type: Natural waterfall 🌊
• Height & Altitude: Not officially documented, adding an element of mystery to the site.

Air Terjun Tanah Merah derives its name from the reddish‑brown soil that lines the surrounding riverbanks—an earthy hue that becomes especially striking after a rainstorm. While the waterfall itself is not listed on major tourism brochures, locals consider it a cultural landmark, often visited for family picnics, traditional rituals, and casual swimming. The cascade feeds into a series of natural pools that are perfect for a cool dip, and the surrounding forest is home to a variety of endemic birds and small mammals, making it a mini‑sanctuary for wildlife enthusiasts.

The waterfall’s relatively low profile has helped preserve its pristine condition. Unlike more commercialized sites, there are no large‑scale facilities or souvenir stalls—just the raw beauty of Borneo’s rainforest. This makes Air Terjun Tanah Merah an ideal destination for eco‑conscious travelers seeking authentic Indonesian nature.
