Many travelers transit through Batangas in order to catch a ferry to another island. Batangas has a large port with boats going almost everywhere in the Philippines. The boats/ferries caled RoRo Roll-on, Roll-off usually can accommodate your own vehicles. Schedules change frequently so check ahead of time. Also, the terminal is a focal point for many islands and therefore sees a lot of traffic. Expect longer lines and waiting times especially during public holidays, especially Holy Week. Fortunately, the Filipino culture observes and respects queueing so lines move orderly and quickly.
