The most effective day trips in Santorini are the watercraft and also wine scenic tours. Every trip I've tackled Santorini has been fantastic (or really great)-- and I've never ever had a poor experience. It's not absolutely essential to pre-book tours before arriving but if you get on a brief browse through (much less than 5 days) it's most likely a great concept to schedule your excursion beforehand. From June to September the finest trips can be fully booked weeks beforehand.
