Mountain
Mount Pinatubo is an active stratovolcano on the island of Luzon, famous for its catastrophic eruption on June 15, 1991. This event was the second-largest terrestrial eruption of the 20th century, ejecting such vast quantities of ash and sulfur dioxide into the atmosphere that global temperatures temporarily dropped by approximately 0.5 degrees Celsius. The eruption caused the summit to collapse, forming a 2.5-kilometer-wide caldera that eventually filled with rainwater to become Lake Pinatubo. Prior to 1991, the volcano was heavily forested and largely considered dormant, serving as the ancestral home of the indigenous Aeta people. Today, the stark, lunar-like landscape created by lahar deposits attracts hikers and off-road enthusiasts. The trek to the crater rim reveals a memorable turquoise lake whose color shifts depending on the season and chemical balance. Volcanologists maintain strict surveillance of the site due to the ongoing threat of lahars (mudflows) during the rainy season and its potential for future activity.

📋 Practical info
Getting there
Reaching the crater typically starts from the town of Capas in Tarlac province, where visitors board a 4x4 vehicle to cross the expansive lahar fields before beginning the hike.
Best season
The dry season, usually between January and May, is generally considered the best time to visit, as the trails are less muddy and the crater lake exhibits its famous vivid turquoise color.
Terrain & paths
The journey involves off-road driving over bumpy volcanic ash beds, followed by a moderately easy but rocky walking trail that gradually ascends towards the volcano's crater lake.
What to bring
It is highly recommended to bring sun protection, sturdy hiking sandals or shoes that can get wet, a dust mask for the ride, and plenty of drinking water for the entire day trip.
Parking
Parking is typically available at the designated base camps or tourism offices in Capas, where local guides and 4x4 vehicles are officially arranged for the expedition to the volcano.
Safety
Visitors should always check for official travel advisories, as heavy rains can trigger dangerous flash floods or lahar flows in the valleys, occasionally causing immediate access closures.
Time needed
A standard guided tour usually takes almost a full day, including roughly two hours of off-road driving and about three to four hours of round-trip hiking, plus ample time to view the crater.
