The Red Sea is definitely one of the places at the top of our list to dive! I hear that it's the gold standard for diving.
Your search and the thread it spawned is indicative of the internet. Kind of like a shotgun going off and you're playing "catch the
golden BB".
In but one example, and there were many posted before, you hit on the Red Sea. It is a holy grail for many divers. It is in exotic land, it offers many side rtrips, the diving is, what? Legendary? Okay, in a way it is.
To continue along on this point, the Red Sea's North End (Sharm) which is where North Americans most likely will venture, is 98% wrecks. Some quite spectacular with cargo remnants to marvel over... some quite subdued and mystical- antiquities of wooden bones cast on a shoal.
The "regulars" here, the Brits... they are so bored with seeing the wrecks that they swim off into the blue in search of Sharks. Maybe I just hadn't seen those same wrecks as much as they had- I'm still interested.... or maybe I had seen a lot of sharks in my past. Results may vary, as they say!
What constitutes a "
Gold Standard" might be as elusive as your original quest, a 4-5 Star resort in the Caribbean with great diving.
As was shown in this thread, there are all sorts of undersea wonders available, some are well known, others are just very hard for us or anyone to get to. Impossible to get to? Los Roques, Swan, and others. Any number of Caribbean islands can not show you the best they have because of island geography versus population center location. Grenada is a perfect example.
It's a whole big dive world out there, but if your travel time limits you to the Caribbean, don't despair~ there's lots to see right in our own back yard. On a world scale, after you have seen everything that the Mar Caribe has to offer, it holds no candle to the critters in the SoPac, and our wrecks are no big draw... in comparison.
But it takes a lot of diving and travel right in our own back yard to draw all or most of what this local zone has to offer. Just as I smile when somebody bubbles over with "Gee, I just had
the bestest diving ever at Club Dread", but no bigger smile than I get when I hear someone tick through their five Caribbean visits and then say they were now officially bored and want to see
some real diving.
There's a lot to see in the Caribbean, it might not be on someone's Gold Standard list, but there's a lot to recommend it for the first thousand dives or so.
