I had the pleasure of visiting in 2002. For nearly two weeks we partied from dawn to dusk on the beaches, enjoying the stunning views and liberating music. From its psy/goatrance roots, the festival has branched out to offer reggae, world music and many other genres. And when you're partied out, you're already in the perfect spot to recuperate.
One word of warning though - each year the festival gets raided by the (extremely ineffective) Greek police, so keep your funny substances at home or well hidden (dig a hole). The criminal penalties for posession are absolutely draconic, but as with all Greek authorities, 50 euros will probably solve your points of contention.
