One of the important attractions you should not miss is crossing the “the longest bridge in the Philippines spanning a body of seawater.” (wikipedia). It is more than 2 kilometers long. I say it is a little bit of a roller coaster. As passenger, you may opt to get out of your car/vehicle and just go to the sidewalk for a more spectacular view of the stretch between Leyte and Samar. Warning: vehicles are not allowed to stop unless they are dropping or picking up commuters. So you can just get off your car, walk, enjoy, and take photos while your driver goes ahead and picks you after he makes a U-turn at the end of the bridge and from where you came from. I hope you dont have fear of heights.
There are picnic sites on the shore near the bridge and I know that you can rent a boat to tour you around the area. They charge Php1500. You can request them to take you to one small island that rests one of the columns supporting the bridge.
