On clearer days, you can see the other islands in the Hawaiian chain from Oahu. The ones in this photo are Maui and Molokai. Maui is taller and Molokai is flatter. Sometimes you can also see Lanai, which would be further off to the right. I think they all used to be part of the same land mass above sea, millions of years ago.
I haven’t been to Maui in ages, but it’s currently swamped with tourists so I think I’ll stay away for a bit longer. Molokai has a reputation for keeping to itself, which I can respect. ‘Nuff hotels already.
