6. Alila Villas Uluwatu – Bali, Indonesia
Built on the edge of a 100-meter-high cliff, Alila’s stunning infinity pool appears to spill into the Indian Ocean. While it doesn’t top global size charts, the sheer sense of openness and peace it offers is unmatched. The design is sleek, the views endless, and the atmosphere serene. This pool proves that grandeur isn’t just measured in gallons—sometimes, it’s measured in goosebumps.
