Hawaii to Cycle

From what I remember, and that was good few years since I lived there, Hawaii is not the most bike friendly place, don't be disappointed.  I lived in Honolulu first and rode almost anywhere in the city, but was afraid to ride to the 'other side' on Pali Hwy (I'm not even sure if it's legal to ride through those tunnels).

Maui was much better and you just can't miss the ride up and down the Haleakala volcano, just make sure it's not raining up there or you can kill yourself on the way down (I almost did). For New Years if you are into parties - Lahaina on Maui or Honolulu on Oahu.

As far as camping - there are state campsites on Oahu, but you need to get a permit, never tried that one. A lot of people live on boats and other floating devices in Honolulu. I would go and read bulletin boards at Ala Wai harbor and Keehi Lagoon if that's of any interest. Good luck!
