回复：Thank you. I like enjoying the places with a slow pace

coffee plantation (Nice place to go; but not the cheapest place to buy kona coffee. There are little stores in Knoa may sell not too famous brand at very low price for 100%. If you want 10% then you can buy it at local grocery store.)
tropical fruit plantation (didn't go)
macadamian nuts plantation (didn't go)
rain forest park (nice place, this is where you can go when weather is not good and it provides umbrella. )
Hiking (paid tour take you go deeper into the island but there is nothing so spectacular that makes you say wow.there is a tour to go to waimea which worth a try.)
Glass Bottom boat to see tropical fish (cheap; but depends on weather since it only goes 1 mile away from kona. We did not see many fish; but saw dolphins)
