10 Best Islands in the World for a Week-Long Vacation in 2026

9. Palawan, Philippines - The Last Frontier of Paradise

Palawan represents the Philippines' crown jewel of natural beauty, where pristine limestone karsts, underground rivers, and some of the world's most biodiverse marine ecosystems create an island paradise that offers week-long adventures through landscapes and seascapes that seem too beautiful to be real. The island's commitment to environmental protection has resulted in numerous protected areas and marine sanctuaries that preserve unique ecosystems, including the famous Puerto Princesa Subterranean River National Park, a UNESCO World Heritage site that features one of the world's longest navigable underground rivers flowing through spectacular limestone cave systems. El Nido and Coron have become legendary among travelers for their dramatic limestone cliffs, hidden lagoons, and crystal-clear waters that provide perfect conditions for island hopping, snorkeling, and diving adventures that reveal underwater worlds filled with colorful coral reefs, tropical fish, and historic World War II shipwrecks that have become artificial reefs supporting abundant marine life. The local Filipino culture in Palawan reflects a blend of indigenous traditions and Spanish colonial influences, evident in the warm hospitality, delicious cuisine featuring fresh seafood and tropical fruits, and traditional festivals that celebrate the island's rich cultural heritage and connection to the sea. A seven-day Palawan adventure allows time to explore multiple regions of this elongated island, from the northern limestone landscapes of El Nido to the central underground rivers of Puerto Princesa and the southern diving paradise of Balabac, while also providing opportunities to interact with local communities, participate in conservation efforts, and experience the authentic Filipino island lifestyle that makes Palawan a truly transformative travel destination.
