The kids will sleep soundly after frolicking by the seaside at Carrillo Beach. Search for cute critters like crabs and snails, stick a toe in the water or maybe even fly a kite!
If you like the word "free" as much as most people do, you'll be pleased to know this stretch of coastline is exactly that. Carrillo Beach is located in Guanacaste. To keep your itinerary full while you're in these parts, also drop by Samara Beach, Buena Vista Beach and La Selva.
