As of Dec 2009 there was diving was allowed at the Salt Pier, however, you must go through Buddy's Dive shop (that's the only shop we know of that has been granted permission to dive the site). My wife and I did a night dive at the Salt Pier with 6 others and a guide. The night dive was amazing! Lights from the pier shine down into the water giving a 'full moon' effect when you're diving. We saw squid, seahorses, frogfish, eel, and a huge sting ray sleeping on the sandy bottom. There's also construction equipment that has been at the bottom for a while that has some nice growth on it and is used by all sorts of aquatic critters as a home. The surface swim from shore to the descent point takes a while, but is well worth it. Easy entry and exit as well.
