THe park was devistated from Katrina. Beach and dolphin swim along with restaurant and dive shops reopened. You cannot walk through park, they shuttle you on a truck. There is very little vegitation on beach, new plants, trees looked like they were chewed on. They have done great job with restoration. As far as snorkeling goes, alot alot of sand has covered everything up. Brain coral is starting to come back to life. Still fish out there. Along the barrier reef the damage was not as bad as it was close to the coast. They had rain for 72 hours and alot of stuff went into water and killed the coral. WE were there 10/27/06. So I guess this is a good update 8)
