Experience nature in fascinating and transformative ways
What my guests say…
Thanks to you, I have rekindled my enthusiasm for rocks.
Audrey Emmett
Great knowledge and a fabulous guide. Loved the morning.
Gail Bradfield
It was an amazing and unique experience. Ntobeko has never taken such interest in flowers before, so your appeal extends beyond those already into natural phenomena. It was really a great experience.

You turn geology into poetry.
Dr. Andrew Baxter
John was able to seamlessly switch from talking about the unique geological features of the park, to identifying the bird that landed nearby and discussing the plant on which it landed. This knowledge provided us a much more comprehensive understanding of the Kruger ecosystem than a typical safari. In addition to his considerable breadth of knowledge, we found John to be very personable, easy going, and focused on keeping his clients safe while guiding in the bush. When we plan our next visit to Kruger, we will definitely book with John again!”

The way John Roff took us on a journey through time…..was deeply soul stirring.
Stories, mystery, the ancient past and distant future – all present in the rocks we walk on today. An experience that left us feeling humbled by Mother Nature.

John tells you about the places rocks have come from, and what made them what they are.
Lynn Hurry
I have known John for long enough to recognise his passion for geology as the foundation on which all of the biosphere is built…he brings an unusual curiosity to his time in the field, and adds an insistence on finding answers to the questions…

John Roff took us on a guided walk in the Karkloof Forest in celebration of my sister-in-law’s birthday. This was a magical experience – I loved learning about so many beautiful things that I would have walked right past without the benefit of his engaging nature-wisdom, wonder and enthusiasm. He had both adults and kids fascinated and inspired! I highly recommend joining him on one of his walks.

Your amazing knowledge of fauna and flora opened a new world to enjoy when I walk in any forest again. I found the morning most informative and enlightening.
Gertje Strachan
I felt held in God’s hands during the walk.
