I booked a few days in Paia, a surf town on the north shore that's popular for windsurfing, but also serves as a gateway to two popular tourist attractions: the Road to Hana and Haleakalā National Park.
So the morning I had to leave, I -- what else? -- went snorkelling. I walked to Black Rock, which is about a 7-minute walk from the condo. It was around 8am and there were already a bunch of snorkellers out there. Other people reported seeing rays and an eel. I didn't see those things. I did, however, have a moment of panic when I was having trouble swimming back around the point against the current. But aside from some extra/unexpected exercise, I was fine.
