Book at least 2 nights on the island. On one of the days, climb the Volcano. And the other day, have a pizza at the well known pizzeria with a view on the volcano eruption.
We spent only 1 night at Stromboli, and this was a mistake. But we did climb the Volcano, with Magmatrek. We had Lorenzo as our guide. And he was great, taking care of the whole group. But don’t get me wrong, the climb is tough. And although they plan a break every 30 minutes, the breaks are very short.
The result: one of our highlights in our life! Seeing an volcano that erupts in front of you eyes… indescribable!!!
If we stayed for 2 days, then the other day we would have went to L'Osservatorio, the pizzeria that I mentioned before.
