Bacalar – as enchanting as the word sounds, as magical is the Mexican place that bears this name. In the untouched nature of the lagoon town, the colours blue and green take on a whole new dimension, not only pleasing to the eye but also touching the soul. How do you build a resort here? With a lot of mindfulness. The Boca de Agua shows how. It blends in so seamlessly that you could be forgiven for thinking it was part of the ecosystem.
