Isla Mujeres or Island of women was a sanctuary for Mayan goddess of the moon, fertility, medicine and happiness, Ixchel. Much later on, pirates were said to plunder the seas close by, leaving the women on Isla Mujeres while away.
Today, Isla Mujeres is covered by resturants, dive shops, souvenir shops, houses and an incredible coast line.
There's even a man who lives on a floating trash island.
I stayed at Pocna, a super chilled hostel for USD$7.50/dorm with activities galore (yoga, spanish classes, salsa classes, volleyball, aerial silks, slacklining and massage, complete with evening fiesta which came in the form of live music or the resident dj [the extra activites may have changed as they're supplied by volunteers]).
My afternoons were spent on the beach often with a cocktail and lazing in the crystal clear blue water or failing at slacklining.
Truely a vacation away from a vacation.
