Research & Discovery
Coastal Tours


Research And Discovery Coastal Tours, Kangaroo Island (RAD KI) offers personalised land and sea-based eco-tours that provide a unique blend of adventure, authenticity and volunteer research tourism. 

Owned and operated by locals and experienced eco-guides Ro and Phil, RAD KI is driven by a deep knowledge of the natural environment and its inhabitants. 


Blending citizen science and nature exploration, RAD KI focuses on engaging and educating visitors, facilitating hands-on data collection in rarely explored, ecologically sensitive areas and fostering a deep connection to environment and country. 

RAD KI holds a South Australian Marine Mammals Interaction Permit, allowing guests to get up close and personal with sea-lions, seals and dolphins, and even enter the water with them under the right conditions.


With years of experience as tour guides, Ro and Phil bring an expertise to RADKI tours that is beyond expectations.


We specialise in educational and environmental discovery tours along the North Coast of Kangaroo Island.


There is so much to see and discover along the unspoilt coast lines of Kangaroo Island. Check out our gallery!

We would love to hear from you and have a chat about how we can get you onboard. 


Stories from RADKI Guests

Best marine tour company on Kangaroo Island with a great team of people, I would highly recommend.

If you're looking for a unique adventure, showing you the best of the wildlife and wild coast of Kangaroo Island, then I could not recommend Ro & Phil more highly. With so much experience and passion, it's an unforgettable experience with the chance to see so many amazing animals, but also to learn about them and maybe even contribute to research that will help protect them. Get out there and get exploring on Radikal!!
