Chocolate Hills

Overview

The Chocolate Hills cover the interior of Bohol with a field of cone-shaped mounds, a karst landform (kegelkarst) built from uplifted marine limestone that weathered over geological time into close-packed hills. The grass that covers them stays green through the wet months and browns off in the dry season — the dried hills reading as rows of brown cones, which is where the name derives. The formation was declared a National Geological Monument by the Philippine government in 1988 (the National Committee on Geological Sciences declaration is dated June 18, 1988 per one source and July 18, 1988 per another; the year is consistently reported as 1988). The number of individual mounds is most commonly cited as 1,776, though older sources give a minimum count of around 1,260–1,268; there is no single confirmed official count and figures vary by source.

The main viewing deck sits at the town of Carmen, set on one of the higher mounds to give an unobstructed 360-degree view across the field. The hills spread across the municipalities of Carmen, Batuan, and Sagbayan (with outlying formations also reported in Bilar, Valencia, and Sierra Bullones), covering an area officially given by the Bohol provincial tourism office as 14,435 hectares (144.35 square kilometres); some general sources round this down to “more than 50 square kilometres.” Individual mounds typically range 30–50 metres high, with the tallest reaching about 120 metres. Their geological origin is attributed to the dissolution of marine limestone — deposited in shallow seas during the Late Pliocene to Early Pleistocene, roughly two million years ago — by rainfall and groundwater after the area was tectonically uplifted from the sea; the exact sequence of erosion remains a subject of ongoing geological study.

The site is listed in BPTO Table 11 of the 2025 Bohol Tourism Profile under the official designation “Chocolate Hills Complex”, with the primary address at Barangay Buenos Aires, Carmen. It is Bohol’s most internationally recognised natural landmark and a candidate UNESCO World Heritage site.

Location

Carmen, Bohol — Barangay Buenos Aires. The primary viewing complex is approximately 55 kilometres north of Tagbilaran City. The hills extend into the adjacent municipalities of Batuan and Sagbayan. Carmen town centre is the access point for the main viewing deck and the road junction for onward travel to Talibon or Ubay.

Getting There

From Tagbilaran City, take a Danao-bound or Carmen-bound bus from the Dao terminal in Tagbilaran. Travel time is approximately 1.5 to 2 hours. Jeepneys and vans also run this route throughout the day. From Carmen town proper, habal-habal (motorcycle taxi) or tricycle to the viewing complex takes around 10 minutes. Tour vans from Tagbilaran hotels include the Chocolate Hills as part of standard Bohol island day tours.

Practical Info

The viewing complex operates daily from approximately 8:30 AM to 5:30 PM. Entrance fees are set by the Carmen local government; under Carmen Municipal Ordinance No. 27, Series of 2023 (a fee revision that took effect October 1, 2025), rates are reported as: ₱150 for non-Bohol-resident adults, ₱75 for Bohol-resident adults, ₱75 for non-resident children aged 6–12, ₱25 for resident children aged 6–12, with children 5 and under, seniors, and PWDs free. The fee increase drew provincial pushback — Bohol Governor Erico Aristotle Aumentado publicly asked Carmen’s LGU to reconsider it, arguing the hills are a national rather than purely municipal asset — so rates may still be subject to revision; confirm current pricing with the Carmen LGU or BPTO before publishing. Morning visits are recommended to avoid heat and midday haze. The viewing deck involves a climb reported as approximately 200–214 steps (sources vary) to the top platform, which has two separate deck levels. Bring water. No guided tour is required at the main viewing deck; guides are available at the base for those wanting them.

What to Expect

From the viewing deck, the hills extend to the horizon in every direction with no visible edge to the formation — scale, more than any single cone, is what registers first. Morning light comes from the east and falls across the western faces, worth timing a visit around if photography is the goal. The site gets crowded on weekends and through the Holy Week and Christmas periods. The climb to the platform is straightforward but steep; the platform itself is wide, railed, and split across two levels.
