1. Volcanoes. Of Costa Rica’s active volcanos, the most active and accessible is Volcán Arenal, which looms majestically over the town of La Fortuna. Hike the Arenal 1968 trail to see the lava flows and formations left behind by the dramatic 1968 eruption that gives the trail its name. After your hike, try soaking in one of the natural hot springs in the area. They offer an ideal way to relax after exploring Arenal.
2. Ziplining. No family trip to Costa Rica would be complete without a zipline adventure, and Costa Rica offers a wide variety of jungle tours. Some of them feature Tarzan swings, bungee jumping and other thrills.
3. Cloud Forest. These dense, vine-draped, high-elevation jungles are an otherworldly experience for nature lovers. The most popular and accessible is the Monteverde Cloud Forest Reserve, while Tenorio Volcano National Park features a cloud forest and a volcano.
4. Monkeys. Depending on where you stay, you may wake to the call of howler monkeys pealing from the nearby jungle. But the best places to get up close and personal with these entertaining animals are in Manuel Antonio State Park and Corcovado State Park, which are home to howlers, white-faced capuchin monkeys and squirrel monkeys.
