It’s summertime—the best time to visit Minalungao National Park and enjoy the emerald waters of Peñaranda River! Situated near the foothills of the Sierra Madre, Minalungao is accessible by a 3-hour ride from Manila. The 16-meter limestone walls flanking the river make it inviting for a trek; b There are huts that friends and families can rent; you can bring packed food or cook your own.
