About

Quick facts: Saltwater and freshwater mix in surprising ways at 400 meters long Dumalum Creek. Locals say the creek’s double-layered water feels like swimming in two seas at once.

Highlights: The creek features a rare natural phenomenon called the halocline, where layers of water with different salinity create a visible, wavy boundary you can swim through. On calm days, sunlight creates shimmering patterns that highlight this divide like an underwater dance floor.

Insider tips

Wear water shoes to protect your feet from sharp shells and coral bits.
Bring polarized sunglasses to see the splitting water layers more clearly on sunny days.
Visit early to avoid crowds and enjoy peaceful swimming.
Avoid heavy sunscreen to prevent water pollution; use eco-friendly options instead.
