Spent a week in Playa Del Carmen diving with my son - got to say it was amazing. We did 5 - 60’ dives and 1 - 100’.
The viz was amazing, the life was amazing - if you get down there check out these sites.
Manchones Reef - Ok viz - nice current - made for a relative drift dive - not much sea life - nice reef - some damage.
The Aquarium - ton’s of sealife, fish, turtle, stingray, etc... Viz was OK
Los Arcos - Great viz - 100’ lots to see - arches to swim thru, turtles and eel - great location - would highly recommend.
TAKE YOUR OWN Gear - some nightmares - we had all our own stuff except tanks/weights - and that was ok.
