The visit is really worthwhile. It does not require any special equipment except sunscreen, sunglasses and lots of water.
(As of 05/2018) - The journey from Tulum is easily possible by car or bicycle, of course it is also on foot. The bike has a clear advantage here, you can rent this for already 100 pesos for 24 hours and is very flexible. If you come by car, you can pay 180 pesos for the parking. Admission is very cheap at 70 pesos per adult. The ruin is open from 08:00 to 17:00 o'clock, early appearance secures as always the best places (say, there is hardly anyone there and the sun is not burning quite so strongly). In the area of the parking lot you will find everything you need in terms of amenities (food, drinks, souvenirs, toilets), on the premises you will not find such facilities.
For all bathing friends, you have the area also directly via a staircase access to the beach. So if you need a little cooling in between, pack bathing suits.
