In Costa Rica’s Guanacaste Province, 400 miles (644 kilometers) of Pacific coastline vie for attention with tropical dry forests, undisturbed rural towns, and volcano-fueled hot springs. The country’s northern neighbor, Nicaragua (which you can easily visit on a day trip), lost control of this territory in the 19th century, although a distinctly Nicaraguan culture lingers. Sites are spread out, so tours can help sure you easily navigate between the places you most want to see. Inland, the region is noted for Rincon de la Vieja National Park, which offers hiking through a tropical dry forest, swimming beneath waterfalls, and soaking in mineral hot springs and mud baths. Summiting the Rincon de la Vieja volcano is every bit as exciting as the more popular Arenal volcano in Alajuela Province, but it’s less crowded and only a day trip from the beach. Additional nature parks dotting the region offer horseback riding; ziplining canopy tours; and opportunities to view sloths, howler monkeys, and lizards that call the forests home. On the coast, find your bliss surfing the swells of Tamarindo or Hermosa beach or soaking up sun rays on the shore. Snorkel among tropical fish at Playa Conchal, take a catamaran cruise out on the open water, or kayak through mangrove forests—all easily accessible from Liberia’s airport.
