Madeira has:
- the main Island "Madeira" something like +/- 60x20 Km
- Porto Santo Island something like +/- 15x5 Km
- other desert islands

Dont expect to find lots of discos/clubs here. They have a few but not a lot.
Landscape is excellent, really really good, so nature is the main feature here.
You have a lot of ...how do you say "walking? path walking" Tracks? in the forest, you have water falls, montains, you can find a lot of of that in Madeira. You can also watch dolphins, i went in a cruise in a catamaran were they garantie to see dolphins in open see, if you dont, they give you an extra ride next day until you see them, probably you can see whales to. The trip is 3 hours, and i saw a group of +/- 20 dolphins they were just around the catamaran, it's a great experience, because you are not in a zoo or in a swiming pool, you are in open see between 1 and 5 km from shore.
If you like beach, you can go by boat from Madeira to Porto santo where you have 8 km of sand with a golden color, and where the water is crystal clear, looks like those post cards from carebean, but much less expensive :-)
food is more then excellent, with 35 euros you can have a fantastic lunch/meal for 2 persons 20 meters from the see. but you can find cheaper then that, and of course much more expensive also. The weather... always summer !! main temperature is not to high, but is always in a range from 20 to 25 celcius , but different weather, 25 in madeira looks 30 in Portugal.
This week it was always +/- 25 perfect for all activities, but you have to be carefull, in Portugal i am used to the sun, and in Madeira with 25 celcius i get my neck all red... all tourist there from UK, France, Germany, they were all Red :-)
if you see on tha map Madeira is far bellow europe, so it's a very different weather, tropical maybe.
