Zakynthos: Island Half Circle Boat Tour — an adventure that promises to unveil some of the most inaccessible and stunning parts of this Greek island. For $152 per person, you get to spend 7 hours exploring Zakynthos’s coastlines, caves, and beaches, all while comfortably seated in a semi-private group of up to 9 guests. Guided by knowledgeable captains, you’ll visit spots like Navagio Beach, the Blue Caves, Keri Caves, and Mizitres, with plenty of opportunities for swimming, snorkeling, and turtle spotting.
What we love about this tour is the personalized experience it offers through small groups, making it easier to customize stops based on weather and your interests. The safety features of the R.I.B. boats, combined with the inclusion of snacks and refreshments, make it both relaxing and fun. One potential consideration is the size of the boat, which is a bit smaller, but reviews suggest it’s still more than enough for a comfortable adventure. If you’re after an authentic, hands-on day on the water that feels exclusive rather than crowded, this tour is a great choice for families, couples, or small groups looking to see Zakynthos beyond the usual tourist spots.
