This was by far one of the coolest things we've done while living in Hawaii. We had heard about china mans hat and it's been one thing we've wanted to do. Thanks to our good friends, the Pennepackers, we were able to actually do it. They invited us to go camping with them and then the next day we kayaked over to the little island and swam in our own little lagoon. You could also hike up to the top but I had Jocelyn with me and never made it to the top. We hung out there for a few hours and it was AMAZING!!!
