Mount Batulao is an inactive stratovolcano in the Calabarzon region of the Philippines, located in northwest Batangas province along its border with Cavite.

[1][3] It is a dissected andesitic stratovolcano at the northwestern rim of the Taal Caldera which began to form in the late Pliocene period, about 3.4 million years ago.

[5] Other sources say its name may have also been derived from a portmanteau of the Tagalog words bato (rock) and dilaw (yellow) referring to the mountain's color during sunrise.

The age of Mount Batulao is based on the basalts and andesites deposits using K-Ar radiometric dating ranging from 3.4 to 1.34 Ma (Pliocene - Pleistocene) (De Boer and colleagues, 1980; Wolfe and Self, 1983).

[15][16] The secondary growth dipterocarp forest has areas of slash-and-burn agriculture planted with corn, banana, mangoes and other fruit trees.

[21] Its accessibility to Metro Manila and its cool climate, as well as proximity to the popular mountain resort city of Tagaytay, also make it a popular camping destination, with at least ten designated camp sites and basic facilities like water stations, makeshift shower areas at its base and even a convenience store selling buco juice at the junction of two trails.

"[20] Atop its summit is an image of Mary, mother of Jesus where Marian devotees hold healing sessions twice a year.

[5] Batulao's peaks are mostly rocky cliffs that offer panoramic views of the Taal Lake and Volcano, the Pico de Loro mountain range, the coves and beaches of Punta Fuego and Calatagan, and as far south as Mount Macolod and Balayan Bay.

[22] In 1975, the area of Mount Batulao in Nasugbu as well as parts of the adjacent municipalities of Maragondon and Ternate were declared as tourist zones.

It was the destination of choice for affluent Manilans in the area of Tagaytay with its Gary Player-designed golf course, clubhouse, halfway house, village inn, cottages and sports complex with jai alai courts.

[5][27][28] Mount Batulao is home to Caleruega, a major retreat center and popular wedding location that sits on 8 hectares (20 acres) of hilly landscape adjacent to the former Evercrest Golf Club.

The iconic chapel is surrounded by pine trees reminiscent of the Spanish town and has a statue of Risen Christ designed by Ben Hur Villanueva in its front lawn.
