Just a heads up for those interested in birding Bongabon - Baler Road.
I went to Baler last February 16th via Pantabangan-Aurora and the route is very good - almost well-paved all the way. On the next day, I came back via Bongabon - Baler road and that route too is decently passable - a few sections are under re-blocking but most are well paved. Even a car can make it easily through this route. The latter route is much shorter in terms of distance, but longer than the former in terms of time of travel because of more curves.
Baler itself is getting crowded, but still fun to visit.
Here's a few surfing clips from this Pacific Ocean side of Luzon.
