just came back from my tuguegarao trip if your planning to go Sta.Ana vans are available @180 pesos one way fare travel time is 3-4hrs.if your staying in the resort near the town proper don't expect white sands beach you need to go island hopping which is a bit pricey for me coz where only 2 person prices as i remember 1800/boat maximum of 10 person if your going to Sta.Ana lighthouse, verde island is 750, anguib 1,500 or 5,000 for 3 island hopping.
About three hours from Tuguegarao City is the town of Sta. Ana. To get there, you may ride a bus going straight to the town from Don Domingo Bus Terminal in front of a market. To get to the bus terminal, just hail a tricycle and tell the driver that you're going to Don Domingo Bus Terminal, and you'll be delivered there. There are no aircon buses though. When you get to the center of the town (just look for where the public market is), ride another tricycle, and tell the driver to Jotay Beach Resort. You'll be delivered to one of the most beautiful beaches in the Philippines I've seen!
Be very friendly! People here are, and they expect that their friendliness would be reciprocated. Be prepared to pump water when bathing after swimming in the beach, and doing other bathroom/comfort room things.
The water is very "peaceful" and clear. It is so clear that dropping a pebble in a deep part of the sea, we counted until 13 seconds when we cannot see the pebble anymore! The shores are corally. The beach is good for swimming and snorkelling.
The Chico River Dam was built as part of a 7-dam plan to provide hydro electric power to Northern Luzon. The plan failed and presently, the dam is just used for irrigation. I honestly think it's such a waste and the whole idea behind the project was feasible but it would have also meant flooding several villages before the project could be completed.
