As a state park there is a fee for visitors ($5 per vehicle—up to eight people),
Type of snorkel spot: Anastasia rock reef and Saberllariid worm (reef-building worm)
Depth: Roughly 5 to 12 feet
Accessibility: Car/foot
Bring: Mask, snorkel and fins; dive flag; refreshments (though there is a Welcome Center/Gift Shop with stuff for purchase)
When to go: Calm flat surf. The reef is in the break zone, so during heavy surf the reef can be dangerous.
Avoid: Fire Coral, it is ever-present along the rocks; boaters, they pullup right along the reef and anchor with little regard for snorkelers, be vigilant!
What to see: Tropical and reef fish; invertebrates and crustaceans; sea turtles; the occasional shark (especially in October and April)
What to leave at home: Spears and Hawaiian slings. Though you may fish here, you cannot spear from the beach
