companies? there is only 1 company in Cuba :-)

I dove with Eagle Ray a year ago - with the same divemaster
I dove with 12 years ago on my 1st dive. Some other divemasters have
changed.

They've always been good - boats leave twice a day - the
sites have permanent buoys - a year ago we fed 200 pound
black groupers

(that's Guardalavaca)

I've no idea about the US diving site - if you are from the US - you
have other problems with travel to Cuba - if from anywhere else, just
go - and there will be diving.

but, although it's easy to get flights to Varadero - it is probably
the poorest diving in Cuba - and distances are big - so you
can't go there - and plan to dive somewhere else.

here's another link - I think it's Cuban - so not always up
to date

I've been to Guardalavaca, Santa Lucia - interesting bull shark experience,
Ancon (Trindad) - whale shark encounter - but I was sleeping in that day,
Playa Giron - if you like crabs and swamp - and Varadero - nice sand

I've heard good stuff about other sites - but some aren't a accessable -
or have little else to do - like Cayo Largo, Cayo Coco, Jardin
des la REina

Guardalavaca is the only place I've been to where the reef is so close -
you can swim out and snorkel - no need for a boat.

it's a very scenic area - hilly, royal palms
their scuba sites are all boat dives

here's info on the beach area - note the little photo -
where you see whitecaps behind the sailboat - that's the reef

and the shade trees on the beach come in very handy

enjoy,
Sandy
