About 16km southwest of Barcelona is Bulusan Volcano National Park . Just inside the park, Bulusan Lake is a popular picnic spot, and there’s a 1.8km walking trail around the crater lake. When the mist is lying low over the surrounding forest and the birds are singing, it’s a lovely, peaceful spot and the clear, still water makes for an inviting swim or a relaxed hour’s fishing for tilapia. There are no visitor facilities apart from the track around the lake.
