They all have steps, so they're all about the same. Choo- ha was our favorite out of the 3. I went with a 10 year old. Just walk carefully, the steps are always wet.

Yes there are

First off,it is absolutely beautiful and I feel worth the time and money to visit. You won't need a snorkel for anyone,and once you get there you can make the call on the jacket. You can rent them for a think 5 dollars. The stairs going down can be slippery. Enjoy

Si, puedes ir por tus propios medios, no es complicado llegar ni tampoco el acceso y todos lo que se pueda llevara acabo ahí, esta bien señalizado y comprensible.

You can rent life vests at the bigger cenotes but you wouldn't want flippers as there are hanging weeds and rocks also they are not very wide and they have ropes across for safety. Youd could get them from the hotel and most have a box you can borrow from if you really wanted to.

Ours were not included in price. We payed 50 Pesos but we tipped the guy as well.

I don't think they would let you take the bikes away from Coba - plus the bikes there at Coba are not high quality bikes. It would be a little bit of a bike ride to the Cenotes from there - my guess easily over 30 minutes each way. Point is the Cenotes are not far via car and are likely the best way to get there. As others mentioned there aren't great options to lock anything up while you are in the Cenotes.

Hiya, yes they are, all sizes
