Chocolate Hills: Debate arises over Bohol wonder
TAGBILARAN CITY—A living postcard—that is how travelers often describe the iconic Chocolate Hills, a surreal landscape in Bohol that feels almost imagined, yet is undeniably real.
For many visitors, a trip to the province is incomplete without witnessing its most celebrated natural wonder. Among them was Louie Guarin, a retired travel writer and events manager from Sta. Cruz, Manila, who first saw the Chocolate Hills at age 67.
As a child, Guarin imagined them as literal mounds of chocolate—giant drops of candy scattered across the earth. Decades later, when he finally visited in March 2017, reality far exceeded imagination.
“The hills are alive with whatever sound you can imagine. It’s only in Bohol, and the landscape is simply spectacular,” he tells the Inquirer.
Guarin adds: “I wish to visit again the Chocolate Hills and tarsiers, and the famous century churches—and stay at least for a month.”
Spanning about 50 square kilometers across the towns of Carmen, Sagbayan, and Sierra Bullones, the Chocolate Hills form a vast expanse of more than 1,700 cone-shaped mounds. Each rises between 30 meters and 120 meters, shaped over millions of years from layers of limestone, shale, and sandstone.
Seasonal shift
Despite their near-perfect symmetry, their origins remain partly mysterious.
Scientists generally trace their formation to the uplift and erosion of ancient marine limestone once part of coral reefs lifted by tectonic forces. Unlike most karst landscapes, however, the hills contain no caves—adding to their geological intrigue.
The hills transform with the seasons. During the rainy months, they are carpeted in lush green grass. But in the dry season—particularly in April and May—the vegetation turns brown, giving the landscape its famous resemblance to rows of chocolate drops.
This seasonal shift has made them one of the most photographed sites in the country, best viewed at sunrise or sunset when shifting light accentuates their rolling contours. Key vantage points include the Chocolate Hills Complex and Sagbayan Peak, where visitors ascend viewing decks to take in the sweeping panorama.
Local folklore offers colorful explanations for their origin. One tale tells of two giants locked in battle, hurling rocks and earth until exhaustion left behind the scattered mounds. Another speaks of a giant named Arogo, whose grief over a lost mortal love turned his tears into the hills.
Whether myth or science, the Chocolate Hills have become deeply woven into Bohol’s identity—featured on the provincial seal and flag, and even depicted on the Philippine P200 bill.
Beauty under pressure
Declared a National Geological Monument in 1988, the site is also part of Bohol’s recognition as a United Nations Educational, Scientific and Cultural Organization (Unesco) Global Geopark, underscoring its global scientific and cultural value.
Behind the postcard-perfect scenery, however, lies a history of environmental pressure and vulnerability.
The 2013 Bohol earthquake triggered landslides and damaged infrastructure in the area, exposing the fragility of the formation. Even earlier, reports in the 1990s noted instances of hillside alteration linked to development pressures.
In recent years, concerns have intensified over encroachment and land use, including developments, such as resorts, that prompted government intervention and cease-and-desist orders. The Department of Environment and Natural Resources has since moved to remove unauthorized structures within protected zones.
Today, the Chocolate Hills sit at the center of a policy debate.
Proposed amendments to House Bill No. 831 seek to redefine the protected area, reducing the number of hills under strict national protection from 1,776 to 642 while designating others as local conservation zones.
Supporters, including Rep. Alexie Besas-Tutor and Gov. Erico Aristotle Aumentado, say the measure aims to balance conservation with sustainable development and clearer land-use management.
But environmental groups, including Tagbilaran Baywatch, have raised concerns that the proposal could weaken protections and open the hills to further development pressures.
“The reduction of the Chocolate Hills and the buffer zone would defeat the purpose of the law,” the group says in a statement, urging lawmakers to retain full protection.
Board Member Jiselle Rae Aumentado Villamor, who chairs the committee on tourism, stresses the need for a balanced approach.
“Since the Chocolate Hills are a defining symbol of Bohol’s identity, their conservation is non-negotiable,” she remarks.
“But protection must go hand in hand with clear, workable policies,” she notes.
Villamor adds that effective conservation requires streamlined permits, consistent enforcement, and systems that allow environmental protection and livelihoods to coexist.
Timeless wonder
Despite ongoing debates, the awe the Chocolate Hills inspire remains unchanged—even among locals.
For tour guide Gerry Lugod and many others, each visit feels like the first, each view as striking as ever.
“We must protect the hills so future generations can still see them. We cannot afford to lose them, as they are one of a kind in the world,” Lugod shares.
As climate pressures and development challenges grow, calls for sustainable strategies—from stronger local governance to nature-based solutions—continue to rise.
Formed millions of years ago, the Chocolate Hills endure as one of nature’s most extraordinary creations—a reminder that some landscapes are not just seen, but deeply felt.
And in Bohol, their quiet majesty continues to tell a story no postcard can fully capture.
