This is one of the oldest and most visited national parks in Costa Rica and has been greatly missed for nearly a year now after some serious eruptions. Safety is always the first concern and you can be confident that it is safe to visit again now. Some say that it is the best or one of the best volcano parks in the world to visit. It is the only one here where you can look down inside the cone. Plus it is a beautiful cloud forest and nature reserve! I highly recommend seeing it when in Costa Rica and always best early in the morning since clouds often move in to hide the volcano by or before 10:00 AM!
