Philippine Nautical Highway System

It is a system of roads and ports developed by the Philippine government to connect the major islands of Luzon, the Visayas and Mindanao.

[2][3] Its route covers the provinces and cities of Tagaytay and Batangas City of Calabarzon, Marinduque, Romblon and Oriental Mindoro in Luzon; Aklan, Antique, Capiz, Iloilo, Guimaras, Negros Occidental and Negros Oriental, Siquijor, Cebu and Bohol in Visayas; and Misamis Occidental and Misamis Oriental, Lanao del Norte, and Dapitan of Zamboanga del Norte in Mindanao.

[2] This system reduced the previous usual travel time by 17 hours to the different key cities, enhancing the accessibility of the prime tourist destinations, minimizing the handling expenses of goods all over the country.

Each operates multiple daily bus trips over the SRNH between Manila bus terminals sited in Cubao and Pasay and Iloilo City, with connections available in Iloilo for onwards transportation.

The SRNH segment between Manila and Iloilo runs by road to Batangas City, by ferry to Calapan, by road to Roxas, Oriental Mindoro, by ferry to Caticlan (gateway to Boracay, located in Malay, Aklan) and onwards by road to Iloilo City.
