Beautiful spot. Highly recommend.
Our kids loved swimming in the waterfall (make sure you have good water shoes to trek through the path to get there. )
The host family was lovely and even allowed our children to play together.
Nothing on the Big Island is close (no matter where you stay). It was about a 20 minute drive to get us to the main beach parks in Hilo. And it seemed like about an hour to volcano natl park.
