Legend has it that the gods created Dia Island and there's certainly something heavenly about it. On this trip, you'll set sail to the mythical isle whilst enjoying all-inclusive drinks and a tasty lunch onboard. What's more, with plenty of time for swimming, snorkeling and even a spot of fishing too, this trip really gets the holiday vibes going.

Casting off from Heraklion, you'll admire Instagram-perfect views of Castello a Mare fortress as we leave the shore behind. With time to relax and sample a drink from the bar, you'll catch some rays out on deck as we cruise towards Dia Island – the favourite dive spot of underwater explorer, Jacque Cousteau.

Dropping anchor, you can dive into the Aegean and snorkel the same waters as the famous oceanographer or try your hand at some fishing. Then after the crew serves up a delicious lunch, there's more time to top up your tan on the leisurely cruise back to port.

It was a fantastic experience; service was great, the staff were helpful and always put safety first! The day was magical, the water crystal clear, the snorkeling was amazing and the food, although basic, was very tasty and hit the spot. I nearly booked it again for the next day!

The driver picking us up was 20 mins late first thing then had to wait a further 30 mins at the end of the trip so arrived back at hotel much later than planned. The captain was helpful, however he and his assistant didnt seem to engage much with the guests. Lunch was grilled chicken and rice and appeared to have been re heated and served in plastic microwaveable bowls. We usually love boat trips and have been on many around the world. Sadly this trip was dissapointing. Didnt seem very organised

BEWARE. I booked a boat ride for my wife and I and tried to reschedule it due to unsafe sea conditions and windy weather. I'm a serving officer in The Royal Navy of 18 years, and am therefore an expert in sea conditions and sailing. Conditions were dangerous for that size of boat. Taking the weather forecast into account, asked to reschedule for a better day. They refused and were rude about it. Unsafe, they don't care and just want your money. They don't care about your safety or comfort. AVOID

Very prompt pickup and very friendly and efficient crew on boat. A pleasant and relaxing trip.

The whole day was absolutely amazing! Right from the start of the morning the customer service was first class, we received a message informing us the pick up was going to be 15 minutes, which I thought was a nice touch, we were then collected by a MVP (with amazing air con) by a polite and friendly driver who took us and 8 others to the port. We were given very clear safety instructions before and after boarding the boat and then we sat sail, for the best experience of my life!!
