How Close Can You Get to the Arenal Volcano in Costa Rica?

Visitors can hike as far as the perimeter of a high-risk danger zone. Before your arrive at this point, you can explore trails that wind around the Arenal Volcano National Park, El Silencío Mirador, the Observatory of Los Lagos, and the Tabacón Hot Springs. All of these areas are generally safe, but no new construction is permitted, and they are monitored in case the volcano becomes more active.
