1. Watch the Sunset
Santorini is known for its incredible sunsets. To experience it at its best, you must go to Oia. Standing at the top of a ruined castle near the windmill, you’ll witness a magical sight that will leave you spell-bounded when the sun goes down the horizon. Just a heads-up, if you visit in the high season, you may find yourself jumping over a train of heads to get a glimpse of the sunset. But also all the Caldera area from Akrotiri to Oia is a photography sunset heaven
The Akrotiri lighthouse is a great alternative place to experience the remoteness of the sunset. Enjoy some quality time with your loved one, looking at a boat sailing into the setting sun at this relatively less crowded spot.

Boat tours
You can do both the volcano walk and the hot springs as part of a boat tour. Be sure to get a tour that takes in the sunset too. There are also tour options to visit Thirassia (a small populated island that forms part of the caldera ring with Santorini) and Red and Black beach. The boats start from either Athinios port (where the ferries arrive), the Old Port below Fira (for this you can take the cable car down), or Ammoudi Bay (below Oia), and most tours offer hotel pickup to get you to the boat.
Scuba Dive
The best scuba dive tours and courses in Santorini leave from Caldera Beach near Akrotiri. Costs and prices vary by the package booked but are pretty reasonable considering the wonderful location.
Fishing tours
Very professional, very fun fishing tour with lots of hands-on action and a huge lunch. The daytime/lunch tour is best for most but there’s also a sunset fishing tour if that sounds appealing.
Kayak tours
Wonderfully fun! The Morning Tour and Sunset Tour explore the south coast of Santorini (cool but you don’t get to see the caldera). The Round The Lighthouse Tour goes into the caldera and provides incredible views of the caldera cliffs
