Luckily, the park’s valley, located between two volcanoes, is a perfect example of this epic relationship. The Tenorio Volcano National Park is massive and protects almost 32,000 acres of primary rain forest. This dazzling forest is home to an astounding array of flora, fauna, and hot springs! Prepare to witness sloths hanging from trees, insects crawling up leaves, branches swaying in the wind, and much much more.
