If you really want a fun way to tour around P.G., and beyond, then you must do it on a motor bike. You will be hounded by many hawkers wanting you to rent their bikes. There is one owner who can be contacted by the jeep stand/street barrier guard. His name is Rommel. You can rent his Motor bike for around 100 Php per hour. At the end of your time, you will need to refill the gas tank. If you want you can pay for 2 bikes and he can show you around.
Motor bike is also a good way to get to P.G. from Sabang. The jeep is a long wait and the trikes are a back breaker due to the bad road. But you can hop on the back of the motor bike near the jeep stand and they will take you to P.G. for about 100 Php. Much faster and smoother ride.
Want a fun day trip? Rent a bike and take it to Calapan. About 1 hour trip south of P.G. Great town and cheap souvenirs. There is some road construction but just for a little way. But the views you will get will more than make up for any delay due to construction.
