Experience a budget-friendly and time-saving way to explore the magnificent Santorini volcano with the daily boat tour from the old port of Fira. Embark on a 10-minute journey to Erinia, the small bay of the active volcano, where you'll have 1 hour and 15 minutes to marvel at the breathtaking views and snap pictures of the smoking rocks and active craters. Don't miss the chance to explore the famous natural mud baths at the hot springs of Palaia Kameni, a result of the volcanic eruptions, where the ship anchors in the small bay of St. Nickolas for 30 minutes of rejuvenating swimming. Climb down the stairs of the boat and swim 30 meters to the thermal waters. This tour is available throughout the season and repeated only at the high season from 2 pm to 5 pm.
