The ocean in Tulum is beautiful! It has great waves, the water is the perfect temperature for swimming and also seems to be a great place for kite surfing as the ocean in Tulum is filled with kite surfers. They soar over the water often times doing flips and high jumps. It is incredible to watch them and you are sure to see many of them throughout the day. I didn't take any lessons (although I would have loved to) but as you walk up and down the beach in Tulum there are a number of companies that offer lessons.
