Sierra Bullones: Bohol's Highest Interior and Its Guerrilla-Era Refuge

Sierra Bullones occupies a ridge-and-valley zone in Bohol’s east-central interior, among the most elevated ground in the province — its name Spanish for a mountain range, and some of its ridges reach above 500 metres. The cooler air relative to the coastal towns marks it apart from most of Bohol’s tourist zones. Corn, upland rice, root crops, and fruit trees fill the hillside farms; some residents work small-scale logging and charcoal production, activity that has thinned forest cover on certain ridgelines. The poblacion sits in a mountain valley, reached by a highway that climbs steeply from the lowlands.

The municipality borders Candijay to the southeast and Bilar and Batuan to the west, with Dimiao to the southwest; streams from its highlands feed the Loboc River system westward and other rivers running east toward the Mindanao Sea. Its elevated, remote character made it historically difficult to administer from the coast, and it was constituted as a municipality from neighboring lowland parish territory during the American-era reorganization. Bohol’s mountain interior — Sierra Bullones among it — had already served as a natural refuge zone since the Dagohoy Revolt of 1744, when Francisco Dagohoy led an uprising that held out for 85 years in Bohol’s highlands before its 1829 suppression, the longest-running revolt in Philippine colonial history; the same terrain sheltered resistance fighters again during the Philippine-American War.

The patron saint is San Isidro Labrador, observed 15 May, consistent with the farming character of the town; highland barangays keep folk-Catholic kandiriko candle-lighting rites tied to planting and harvest. Cebuano carries distinct mountain-dialect features here, noted by linguists studying Bohol’s interior speech communities.

What’s here, briefly

• Ridgeline views — clear-day sightlines reach the Mindanao Sea to the south and the Bohol Sea to the north, with the Leyte coast visible on the clearest mornings.
• Forest trails — secondary and remnant forest on the steepest slopes, informal and unmarked; poblacion guides can be arranged for ridge walks.
• Upland farms — terraced hillside plots of corn, sweet potato, and fruit trees, a different agricultural picture from coastal Bohol.
• Loboc River headwaters — the system’s upper tributaries rise near here, a quieter counterpart to the well-touristed lower river at Loboc town.

Getting there

From Tagbilaran City, the route runs 1.5–2 hours by jeepney or bus via the Bilar road, then up the mountain ascent to the poblacion; jeepneys depart the Dao Terminal area, and the paved but narrow ascent favours private vehicle hire over public transport. From Jagna on the southern coast, habal-habal covers the mountain road in 45–60 minutes, with sea views across the Mindanao Sea on the climb.

Local taste

The cool highland climate supports crops that struggle at lower Bohol elevations — sweet potato varieties, highland corn, and leafy vegetables. Corn (mais) stands alongside rice as a staple, eaten as mais na lugaw or roasted; wild fern fronds (pako), gathered from forest edges, are a common upland vegetable dish, and some farming families harvest wild-colony honey sold informally at the poblacion market.

Practical realities

Accommodation: none in Sierra Bullones — the nearest guesthouses are in Bilar or Tagbilaran. Pack a layer: the poblacion runs noticeably cooler than the coast, especially January–February evenings and after rain. Route choice: the Bilar road is the more reliable approach; the Jagna route is scenic but narrow, better by motorcycle or 4WD. Timing: mornings give clearer ridge views before afternoon cloud builds over the peaks.

Other places to consider

• Bilar — the nearest town with accommodation, on the approach road.
• Candijay — bordering to the southeast.
• Jagna — the southern-coast approach and its habal-habal mountain route.
• Loboc — downstream on the same river system, for the developed lower stretch.
