When you are new to diving, it's easy to be unaware of your overall bulk, e.g. your tanks, and to allow things like a camera dangling from your wrist or a loose gauge that's not properly attached to your BCD to knock up against the fragile coral.
Those little pieces you inadvertently break off took decades to grow, and the bigger chunks took a hundred or more years. Think about it, and please keep track of yourself!
This photo happened to be taken at the precise moment that another diver clonked me on the head with a very heavy underwater camera, hence the stoopid wide-eyed look I'm wearing. He wasn't used to using UW cameras, and really didn't even notice that he'd let it fall down and hit me, but he actually drew blood. And probably broke off a bit of coral here & there too.
Happily I didn't instantly become shark bait (that whole thing is very exaggerated by Hollywood).
The Devil's Bay Trail goes from the main beach at the bottom of the hundreds of steps (exaggeration) down from the top of the Baths to Devil's Bay beach. It is a challenging trail and most of the time you are either walking in water or climbing on rocks. Some of the more difficult places to climb were aided by wooden stairs or a rope. I did not attempt it, but Bob went with the male Captain of our boat. It is NOT handicapped accessible.
In any case you must wear SHOES (for climbing on the rocks) which can get WET. Teva sandels or something of the sort would be appropriate. Bathing suits or shorts would be appropriate with exposed areas covered in sunscreen. And if you want pictures, you will want at least a water resistant camers.
When we went, the trail was not marked with signs, but with piles of stones (cairns) so watch out for those so you don't get lost.
The other warning I have about this place is - GO EARLY. If you try to go later, there will be a lot of people here as it is another extremely popular location that can get crowded from cruise ship jaunts, charter boats and day trippers.
hiding on the rocks mostly under water are a great deal of poisonous creatures and corals so watch your step! I've been fortunate but i've had a few neer misses with fire coral and sea enenimies(-sp) on numerous occations.
