Shimizu Island, a popular stop on El Nido's Tour A, is exclusively accessible by boat as part of an organized island-hopping tour; solo visits are impractical and significantly more expensive. Visitors typically spend 1-2 hours here for snorkeling, swimming, and enjoying a beachfront lunch, with the full tour lasting 6-8 hours. While generally accessible year-round, tours can be cancelled during the rainy season (June-November) due to adverse weather conditions. The approximate cost is included in the Tour A package, usually ranging from PHP 1,200-1,800 per person, covering lunch, environmental fees, and equipment. It's renowned for vibrant snorkeling opportunities amidst limestone cliffs, and tourists should bring reef-safe sunscreen, a waterproof bag, and expect crowds, especially during the dry season (December-May).
