Pursuant to Chapter II, Title II, Book III of Republic Act 7160 or the Local Government Code of 1991,[22] the municipality of Alcantara is composed of a mayor (alkalde), a vice mayor (bise alkalde) and members (kagawad) of the legislative branch Sangguniang Bayan alongside a secretary to the said legislature, all of which are elected to a three-year term and are eligible to run for three consecutive terms.

Because much of Alcantara's interior is made up of mountains covered in lush tropical rainforest, it is being promoted as a hiking destination for backpackers.

There are freshwater springs located in Camili, Calogonsao, Bonlao, San Isidro, and Madalag which tourists can enjoy.
