Great experience - Great experience. The area is beautiful, lots of different activities packed into one. You hike, scramble over boulders, cliff jump, snorkel. Our guide was great, she took pictures and sent them to us after. She helped arrange a driver for us from Athens who waited and let us visit the temple of Poseidon after before heading back to Athens. I have always been hesitant to cliff jump and figured I would not to any of them, but she started us on just a very small jump and kept moving us up to slightly bigger jumps. I jumped off much higher than I ever expected I would be willing.

Great experience! - Nikki did a great job! The hiking wasn’t too difficult, and the snorkeling was a nice treat. You get to jump off of smaller and then larger jumps. She goes through all the safety measures, so you feel secure. Still, it was a great thrill!

Top experience! - We had a wonderful time with the coasteering team. Niki and Billy created a very good vibe and stimulated every member of our group to push his boundaries. It was a great activity with much variation and a clear goal in a beautiful environment. We look back on it with great pleasure!

An incredible experience with incredible people - We had an incredible time coasteering with the BOA team: Niki, Konstantinos, Vasilies and George around Sounio. It’s a beautiful route that includes climbing, repelling, cliff jumping and snorkelling. The team are amazing, funny, friendly, and knowledgeable, they shared Greek mythology stories as we climbed and their expertise ensured that we felt safe at all times. The team were able to offer transport from near Athens for a reasonable fee so it’s worth asking if you need transport. We both agreed it was our favourite day on holiday, I’d definitely recommend! Thank you team x

Great time - spectacular adventure - Hiking, swimming, climbing, jumping, and repelling under the temple of Poseidon. They accommodated our last-minute sign-up and ensured we had a great time. We'd do it again, and recommend it without hesitation.

Excellent! - It was simply amazing adventure experience to do Coasteering in Sounio with BOA. Perfect combination of bouldering, hiking, jumping off the rocks around Aegean sea into the clear blue waters ( even close to the deepest part of Aegean sea), snorkeling and swimming! I didn't know completely what kind of day, I was headed to. However, at the end of the day it was well worth it. Vasilis, Niki and George took care of each one's safety of every one in the group absolutely perfectly! I would recommend everyone who wants to enjoy the adrenaline and refreshing clear blue waters of Aegean sea and the nature around it to choose Coasteering with BOA.
