I would avoid Summer in Santorini as tourism is high, and cruise ship traffic is heavy.
The weather in the Mediterranean is also warm, so consider your comfort level for time of year to visit.
Secure your transportation before landing at the port, or ask for the taxi cost from the driver before agreeing to the ride.
Traveling via ferry offers amazing views and an efficient means of reaching Santorini from Athens or other Greek Isles.
Don't miss out on the numerous boutiques as you walk the towns on the Island.
Traveling via local bus is economical and easy. Just be sure to be ready at Sunset to capture some beautiful photos!
