Do not leave from Santorini unless you have experienced a boat tour. Its greatest asset is that you can face the impressive caldera and the picturesque villages on its top from the sea. Transfer to port to embark the boat that will sail to the lava island Nea Kameni. You will walk an ascending soil path to approach the crater of the still active Volcano. Then back to the boat to sail to the second lava islet called Palea Kameni where you will find the Hot Springs. Here, you will have an opportunity to swim in the green Sulphur waters. Set sail for the island of Thirasia. There you can swim at the beach next to the port or you can visit the traditional village Manolas by the winding steps, either walking or riding a donkey. You will stay here for about two hours before re-embarking the boat that will cruise along the caldera cliffs, so you will have the chance to take wonderful photos. After approximately 6 hours in total, you will be dropped off at the city center or transferred to your hotel.
