Sorry but having checked this kitelife video I felt like I had to do smthg.
Mauritius is NOT a ''pretty big Island'' and certainly not 200k length or 100km width.. it's actually more 60 by 40km.. so you drive north south 1h30 unless you get stuck in Port Louis at rush hours.
Then there is not much of an african wildlife.. we do have a kind of zoo (casela) where you can find lions and all that sh.. but exept that the only wildlife you can see is under the water, or also birds, bats, tropical forest and dears. (the 'ferney' trek is really nice you can also do canyoning which is pretty fun)
And for the surf (without a kite) don't expect a ''pretty good surf'' the only place from the beach is Tamarin but you have to be lucky to have really good waves. You'll need a boat (or a kite) if you wanna to go to the reef where you can find awesome but dangerous waves.
Well exept that it is a fantasic place beautiful landscape, gorgeous sea, flat lagoon, awesome culture mix and people..
Palmar, Indian resort and Mahebourg hotels are on good spots, expensive tourism though..(not a backpackers destination really but i dont know about villas)
You should enjoy Mru is awesome really
