  • Our boat tour with Thea Seas was beyond amazing! The crew was professional and friendly, and we explored hidden beaches we never would have found on our own. Swimming in the crystal-clear waters of Balos was a dream. Truly an unforgettable experience. Highly recommended!

  • We had an incredible time on the Thodorou-Lazaretta tour. The boat was comfortable, the guide was knowledgeable, and the views were stunning. We loved the secluded beaches and swimming with the sunset as a backdrop. Everything was perfectly organized—definitely the highlight of our trip to Chania!

  • We booked a private boat tour to Balos and Gramvousa, and it was easily the highlight of our holiday in Crete. The boat was spotless, the captain was professional and friendly, and we had plenty of time to swim in the crystal-clear waters away from the crowds. Everything was perfectly organized from start to finish. Highly recommended if you want to experience Chania from the sea!

  • Amazing experience! We chose the Secret Beaches tour, and it exceeded all our expectations. The hidden coves, turquoise water, and peaceful atmosphere were incredible. The crew shared interesting information about the area and made us feel safe and welcome throughout the trip. We would definitely book with Thea Seas again on our next visit to Crete.
