Can you swim in Santorini?

Yes, swimming is safe and enjoyable at most Santorini beaches from May through October. The best swimming beaches are on the south and east coasts: Perivolos, Perissa, Kamari, and Monolithos. Water temperatures reach 24-25C (75-77F) in summer. The caldera side (west coast) has limited beach access and deep water, so swimming there is mostly from boats or at Amoudi Bay.

Is Santorini good for snorkeling?

Santorini offers decent snorkeling but nothing comparable to tropical destinations. The best spots are the rocky northern end of Kamari Beach, Amoudi Bay, and the areas around Red Beach and White Beach. You'll see volcanic rock formations, sea urchins, small Mediterranean fish, and occasional octopus. Guided snorkeling tours (EUR 50-80 per person) take you to better spots along the caldera walls.

Are the hot springs in Santorini worth visiting?

The volcanic hot springs near Palea Kameni are worth visiting once. The water is 3-5C warmer than the surrounding sea thanks to underwater volcanic vents. Tours cost EUR 25-40 and usually include a volcano crater hike. The water is murky and sulfurous (not crystal clear), and the swim from boat to shore is about 50 meters. Wear a dark swimsuit because the sulfur stains light fabrics.

Which Santorini beach is best for families?

Monolithos Beach is the best for young children, with shallow calm water and a sandy bottom. For older kids, Perissa and Kamari work well. Kamari has lifeguards during summer months. Avoid Amoudi Bay, Caldera Beach, and White Beach with children due to deep water, difficult access, and lack of facilities.

Can you swim in the caldera?

Swimming directly in the Santorini caldera is possible but limited. Amoudi Bay below Oia is the main caldera swimming spot, with deep, clear, cold water accessed from rocks. The rest of the caldera coastline is vertical cliffs with no beach access. Most people experience caldera swimming from [catamaran cruises](/experience) or sailing tours that anchor in sheltered spots. ---
