Calapan serves as the gateway to the Oriental Mindoro province with the implementation of the Strong Republic Nautical Highway, an integrated roll-on/roll-off ferry project of former President Gloria Macapagal Arroyo that extends further to the southern part of the Philippines. The Calapan City Seaport is the largest and busiest seaport on the Mindoro Island with ships that travel to and from the Batangas City International Seaport. Calapan is 45 minutes away from Batangas and is accessible by ferry boat and RORO ships.
Calapan is currently one of the only two cities (the other being Puerto Princesa) in the MIMAROPA region (Region 4-B) and serves as the region's administrative center. It is also the center of commerce and industry, the center of transport and communication, the center of religious activities and the center of education in the entire province of Oriental Mindoro.
