Q: Can I drink the water at Cabo Pulmo? A: DEFINITELY! The well servicing the small American community at Cabo Pulmo supplies reliably good, sweet water, piped underground to each house. Most people drink it right from the tap. However because most people traveling in Mexico are concerned about safety of drinking water, VILLA & CASA DEL MAR and EL NIDO have installed reverse-osmosis water purification systems in order to provide you with an extra level of comfort. Purified water is conveniently dispensed at-the-tap in the kitchens. You don't need to buy bottled water at the market.
