Oia is famous for its stunning sunsets and iconic cliffs, but it’s also a fantastic starting point for exploring Santorini from the water. The caldera views, volcanic hot springs, and small islands make boat tours in Oia a must-do for any visitor. We particularly love the experience of cruising past the dramatic cliffs of Oia or swimming in the warm, mineral-rich hot springs — moments that are as memorable as the island’s land-based sights. One of our favorites is the 3-hour caldera cruise which offers a quick yet rich taste of Santorini’s natural beauty, especially for those short on time. If you’re after a longer, more relaxed adventure, the full-day catamaran cruise with food and drinks provides ample opportunity to soak up the scenery, swim, and enjoy a delicious Greek feast.
In this guide, we’ll compare two top-rated boat experiences. Whether you’re craving a quick scenic cruise or a full-day sailing adventure, you’ll find options that match your travel style. Here’s a quick overview of what’s on offer.
The list below includes a 3-hour scenic caldera cruise that highlights Oia’s cliffs and hot springs, and a full-day catamaran cruise with snorkeling, food, and drinks, perfect for those who want a leisurely day on the water. Both options deliver memorable moments, but each suits different tastes and schedules.
1. Santorini: 3-Hour Boat Tour to Oia & Thirassia Hot Springs

How to Choose Your Ideal Boat Tour in Oia
When selecting between these options, consider your schedule, budget, and what kind of experience you’re after. If you have limited time but still want to see the highlights, the 3-hour caldera cruise is an excellent, affordable way to tick off key sights like Oia’s cliffs and hot springs. For travelers who want to relax and indulge in a leisurely day of swimming, snorkeling, and feasting, the full-day catamaran cruise offers unbeatable value and comfort.
Think about whether you prefer a quick scenic snapshot or a more immersive experience. If you’re after a customizable route or specific spots like volcanic hot springs or beaches, the full-day cruise allows you to select your preferred stops. Booking early is advisable, especially in peak summer months, to secure your preferred time slot.
In summary, both tours showcase the best of Santorini’s waterside charm. The 3-hour caldera cruise is perfect for a quick, scenic overview, while the full-day catamaran provides a relaxing, all-day adventure. For a shorter trip that still captures the island’s magic, go for the caldera cruise. If you want to indulge in swimming, snorkeling, and Greek food, the full-day cruise is hard to beat. Either way, booking in advance ensures you get the best possible experience—so pick your boat and enjoy the magic of Oia from the water.
