What To Expect
The most beautiful summer activity in Athens is taking place in the Sounio area - the most impressive area that you will see close to Athens. The crystal light blue water of the Aegean Sea with the gorgeous rocks of the coastline offers endless adrenaline. The coasteering activity combines the high jumps from the rocks, swimming, snorkeling, and climbing in the rocks above the sea - on the coastline below the Poseidon Temple. Coasteering can be determined as the absolute summer activity in the Attica region.

Jumping off rocks!
Marc G,Jun 1, 2026
- Review from Viator
5.00Two middle-aged parents and two teenage boys jumping off rocks into the Mediterranean Sea. What could go wrong? Nothing. Our 14 year old son said this activity was EXACTLY what he wanted. After meeting our excellent guide, suiting up in wetsuits and neoprene shoes, we were off on a short hike through the beautiful flowering seaside hills to take a dip in the sea. Then we climbed our way to about half a dozen spots where we could jump from the cliffs at various heights. We also climbed up and down some spots with the help of a rope. The entire time our guide lead us expertly through the trail and we always felt safe. We ended with a long snorkel to the end of our trail where we saw fish (and maybe an eel) through clear blue waters. After our tour, we ate lunch at one of the seafood restaurants nearby. An excellent tour! Note: if traveling by taxi to the meeting point in Sounion, be aware that the taxis/rideshares do not like to pick up riders traveling back to central Athens. We solved this by taking a rideshare about half way (Vouliagmeni) and then taking a second car from there to Central Athens.
Great experience

5.00Great 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!

5.00Nikki 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!
Wonderful constant trip

5.00We 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

5.00We 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

5.00Hiking, 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.
