From San JosÃ©, the capital of Costa Rica, any tourist agency can direct you to the town of La Fortuna which is the nearest town close to the volcano.
The volcano is not always easy to photograph because of low clouds and some persistent rain. When the sun is out, take the photo as soon as possible because weather conditions change quite suddenly.
