i'm a fan
go on a weekday if you can and buy your ferry ticket online
it can get busy in the later afternoon and weekends and especially holidays, if you can go early - sunning between 10-12 is the same as 12-2 and you can duck out before the crowds if it gets to be too much
overall people are very respectful and well, normal - there is definitely a freedom to going clothing optional - if you think its all buff boys and big breasted women stay home - its just a bunch of normal regular people (like you) enjoying some time at the beach.
the complaining about the noise must be the weekend afternoons and the notes about the litter is not the beach's fault, it's our fault for being disrespectful.
other useful information:
rocks, bugs are part of nature ... duh
its a beach, not a resort - pack a lunch, water and bug spray
litter bins are only 100 or so feet apart, you may want to try them
under-developed here is far better than over developed (it's a beach, remember?)
cheers toronto and stop your whining - you have something good
