If you want to fly choose another island
No GA on Mauritius. Foreign aircraft there for more than a week I believe have to pay sales tax on the value of the aircraft.
I believe Air Mauritius used to have a few Cessna's for their (mostly South African pilots ... when SAA had the contract to manage them), but no longer.
If you want to fly hop on a plane to South Africa 3.5 - 5.5hrs depending where you are going..
Friends of mine work for Air Mauritius; I go there every so now and then, but not for the flying :-/
