I'm not that familiar with the area but I'm pretty sure there isn't much in the way of diving south of Tulum. I also don't think you will enjoy the diving in Akumal - but it will do in a pinch. If you are in the south I would suggest cenoting diving is your best bet. There are lots of dive options - I recommend Aquanauts in Puerto Adventuras (Dennis) but as I say there are lots of options. Dennis also does reef diving and will show you the best of what's in the area. I like to take the 'day trip' to Cozumel but it will take 'all day'. I stay in Playa and can walk to the ferry if I want - straight to bed after diving - so it's not a big deal for me. If you have to drive there, park, take the ferry, dive, take the ferry back, and drive home - it could be a long day. You might dive right out of Playa and save Coz for your next trip. If you do find something south that's worthwhile I'd like to hear about it when you get back. (If you go far enough south you can dive in Belize...Ha Ha)
