I had a great time and experience today. Amelia, the guide, was wonderful with every tour participant. She was very informative and knowledgeable. The 3-course lunch, which included Alcatra (slow-cooked beef), the speciality of this region, was delicious. Generous portioning. There was a free flow of beverages as well.

5 different experiences (all related to nature and volcanos) in a 8 hours tour, including a two hours trekking. Nice experience. The guide was also a good driver.
