Take the Pantabangan route, especially if you are bringing your car. The Bongabon route is the worst as the whole stretch is basically rough road (you can consider this if you bring an SUV/4x4, because this is the shortest route).
Baler is a compact but surprisingly adequate town with friendly and courteous inhabitants. The place is close to wonderful nature spots such as the Ditumabo Mother Falls and the beautiful Dicasalarin Cove.
I would recommend this to anyone who loves beaches in particular and nature in general.
Rustic. Unspoilt. Gifted with beautiful natural wonders like beaches, coves, caves, waterfalls, cliffs, rock formations and mountains.
Quiet city. Friendly people. Jerry's buffet great for the price. Be prepared to walk or take a butt pounding tricycle ride.
No jeepneys. No taxis. Excellent museum. Bone up on the Siege of Baler before visiting the church. Hometown historian claims the love story of the movie Baler based on the siege is not what actually happened and is more tragic. Find him and ask him yourself.
