Founded in 2017, BOA (Base Outdoor Activities) is an adventure tour guide company that offers group adventures across Greek. A team of passionate and professional instructors, their adventures cover all four elements - with excursions to suit thrill seekers and young families alike.

Based in Athens, their tours travel across the coast and into some of the most remote inland areas - exploring jagged coastlines and deep ravines alike. Popular locations in Greece include Attica & Sounion - areas renowned for their architectural relevance and stunning natural features.

Join them for their best-selling coasteering excursion in Sounion - home to lagoon-like waters and the Temple of Poseidon. At the southernmost tip of the Attic peninsula, BOA instructors will have you tombstoning into the unknown and exploring along the tideline.

For the more adventurous, BOA's canyoning excursion in Attica offers whitewater thrills for true adventures - following a natural trail from source to sea. If waterfall jumping and abseiling is your thing, this tour is not to be missed!

About Cayoning Excursion at the Manikia Gorge on Evia Island.
Great instructors. Very supportive, friendly, and fun and also felt completely safe doing activity with them. Lots of really good photos and videos taken by providers. Would highly recommend the providers and would have loved to do more activities with them.
