Our guide was extremely knowledgable on all aspects of our tour, answering all questions throughly. Myself and my partner were throughouly pleased to have met our guide following several days of poor tours with other guides. She ensured we saw everything we payed for to a high level and was very friendly and helpful. The tour itself was amazing, definitely worth doing, don't book through travel agents as it is more expensive, this Viator trip was personal and catered for your specific wants and needs. We would definitely use again through Viator - exceptional knowledge and very friendly.
