Start with pickup from Heraklion or the surrounding area. Drive over to Kastelli by bus to board your boat. Balos are Gramvousa are located on the West part of the island. Depending on the area your hotel is located is around 4 hours by bus to the place where the boats depart. Embark the boat from the village of Kasteli and head over to Balos Lagoon and enjoy plenty of time to swim in the quiet crystal clear waters, walk across the golden sand beach and soak in the sun as you relax. Cruise across the western Cretan sea and arrive at the tranquil Gramvousa. Swim along the coast and stroll up to the castle on the hill to admire panoramic views of the natural landscape as you hike up to that point. The drivers will be awaiting you at the port, in order to begin the drive back to Heraklion.
