The Island of Bohol is oval-shaped mainland surrounded with 73 smaller islands. Bohol's mountainous interior is home to rare and endangered flora and fauna. At certain points, hills drop steeply to the coast from a maximum elevation of 870 meters above sea level. The interior uplands are fit for agro-forestry and high value agricultural production. The central and northern lowlands have also fertile grounds and abundant water supply. Over a hundred caves have been identified, the biggest of which is found in the eastern part which makes Bohol ideal for spelunking adventures. The Chocolate Hills in Carmen, Bohol are considered one of Philippine's natural wonders and Bohol is often referred to as the Jewel of the Philippines. They are hills made of limestone leftover from coral reefs during the ice age when the island was submerged. They turn brown during the summer, hence their name.

Most beaches are of white sand. The sand is often of such high quality that it is exported to other beaches in the world. The most well known of these beaches are in Panglao Island, and there, numerous islets have similar, yet untouched and pristine beaches.

The Loboc River is the most famous, running from the southeastern coast to the center of the island. It is famous for its River Cruise going up to its water source. The largest, Inabanga River, runs in the northern part of the province.

Numerous waterfalls and caves are scattered across the island, including the beautiful Mag-Aso falls in Antequera. Mag-Aso means smoke in the native tongue. The water is cool and often creates a mist in humid mornings which can hide the falls.

Panglao is a small island southwest of the main island, connected by a causeway to Tagbilaran.
