Uncle Al,

You are spot on about Little Beach and Sundays. Wife and I owned a home on Maui and spent many a day at LB. Monday thru Thursday are probably the best days to enjoy LB au naturel. Best in the morning where I would say 90% are nude- enjoying the serenity and to die for views from LB. Late in the afternoon more people start coming. In the afternoons I would say it is about 50% nude. Lots of locals (whom normally dont go nude) and curious textile tourists from big beach next door.

Sunday evening is a total different story on LB. We try and get out of there by 3pm. Locals, aging hippies,pot dealers from Hana and places north all head to the LB for the drum circle. I would say that less then 10% nudity during this time and it is sort of a zoo in my opinion.
I guess it is worth seeing once in your life (I heard Steven Tyler was there one Sunday recently-leading the drums circle.) We personally would not feel comfortable au naturel on Sundays. Each to his or her own however.
