When you say Laguna, instantly people will ask you, "are you looking for a cheap private pool?" but one big tourist attraction there is the Pagsanjan Falls. This area is way too famous to Koreans and here's an example of that. My ex-students (when I was still teaching English to Koreans) decided to have their winter vacation in Manila and asked me if I can take them to Pagsanjan falls in Laguna as their Uncle (My student as well) suggested that they'll have a wondrous experience. This was an all paid expense trip because they feel that me taking them to the place is a big bother. We also went shopping the night before. 

We then decided to go to a spa and because the trip was pre-arranged by their uncle, we ended in a KOREAN SPA which is a bit of a bummer for them because they're expecting to have more Pinoy time. 

I didn't take a lot of pictures. 

I can't remember how much it was at 88spa but we paid around 1,200 or 1,800 per person for the Pagsanjan falls.
