Siargao, Philippines

Siargao's Cloud 9 surf break delivers world-class waves that attract 30% fewer tourists than Boracay, preserving its palm-lined roads and secret lagoons. This Philippine island maintains a laid-back vibe that Boracay lost a decade ago, with over 60% of its coastline still undeveloped. The secret is leaking fast, however—visitor numbers have surged 40% since 2019. For now, it outperforms #6 in authentic island experiences, offering hidden lagoons like Sugba and Magpupungko tidal pools without the resort crowds. A visit before 2026 ensures you experience this gem before it transforms.
