Boat rental to the Taal Volcano can vary from P800.00 to P900.00 (as of January 2008). If you get approached by touts be firm and do not be swayed by the extras that they may "offer" (e.g. life vest - it is regulations that all boats have them.)
This type of vehicle is very common in Taal and in the Philippines in general. This is actually existing a long time ago in every part of the archipelago. This is built by vehicle manufacturer in the Philippines. If I remember it right, this type of jeep is available only in the country. Jeep like this made of stainless steel is the most expensive and elegant looking.
You can also use this jeep on private tour. The only problem is that it is open and definitely no airconditioning unit. Therefore there is no protection during warm season.
Taal is overcrowded with tricycle. This resulted to heavier traffic on busy streets. Tricycle is a major means of transport in getting around the town. Before boarding, ask how much is the fare. You can also bargain for the fare if you are going to specific tourist destinations.
Personally, I do not have problems with tricycle drivers. Most of them are good people. This is their means of livelihood.
You will see a lot of jeepneys on the road of Taal. One can ride jeepneys to move from one town to another. You can also negotiate in renting a jeepney to reach specific tourist attractions/destinations.
You can board a jeepney anywhere on the road of Taal. I do not see any jeepney stop or anything to this effect. If you see a jeepney coming and you want to board, just raise your right hand giving the driver the idea that you want to board.
The jeepney fare will depend on how far you'll gonna go. There is a minimum fare though. Pay your fare upon boarding or before getting off. You can do either way, no problem.
