Such a serene place but a bit expensive.
If its your first time I'd suggest you go with tours, hikes and caves needs some tour guide which will be costly if you're doing it solo.
Expect foods to go around 200-400php. I suggest to go to the canteens underneath where the public market is as I found that where the locals eats otherwise go to spots just by the road.
3k+ for 3d2n tour and it comes with the accomodations
1.5k for guided tours
1k+/day for food
Extra money for souvenirs and pasalubong.
