Mount Pinatubo and the crater lake
The 4x4, the trek to Pinatubo’s crater lake, and why lahar conditions decide the day.
Adventures
Pinatubo’s crater lake is reached from the north side, typically via Santa Juliana in Capas, Tarlac. A 4x4 crosses the lahar field. You then walk a dry riverbed that is easy underfoot until the sun is high, when it is simply hot.
Start early. The standard trek is doable for a patient beginner and a poor idea for someone who skips water. There is little shade. Guides are required. Fees for the vehicle and the guide are separate from lunch.
After heavy rain the lahar streams change and operators cancel. That cancellation is the correct outcome. Do not shop for a driver who will go anyway.
It is a long day trip from Manila if the group is ready at dawn, and a better overnight in Capas if it is not. The lake is the reward. Swimming rules depend on the current advisory. Follow them. The 1991 eruption rebuilt this landscape; it is not a pool with a lifeguard.
