Cost us 35Euros to find our way back - but the trip was wonderful - was great to swim in the Hot Springs - wine was flowing - and the weather was great - onboard staff were lovely too!”

De plus, c’est vraiment compliqué retrouver son bus au retour, aucune indication sur ceux-ci. Très peu de temps aussi au sommet du volcan puisque le guide parle en anglais en premier donc ça donne peu de tenps au Franco de gravir le volcan par la suite.”
