The Spirit of Adventure Team


The people that make it happen!

The single most important factor that dictates the success of your holiday is your instructor or guide. We believe our guides are the best there are – their experience and enthusiasm will ensure that you have an adventure holiday to remember.

All of our adventure, activity holidays are led by an experienced and English speaking guides and in most countries we also use local guides and services.

Spirit of Adventure was started by John Diplock and Sandy Simpson in 1993.
