Your favourite hikes in madeira

Hi, it's my 2nd time on the island and my girlfriends first.

Were staying in Sao Vincent in March for one week and looking to do 1 long hike (16km+) with various shorter hikes on other day.

We enjoy scrambling and aren't worried about exposure, what would be your absolute favourite hikes on this beautiful island? Ideally not any that have crowds, although in march I can't imagine it being very busy

Also any other activiites any locals reccomend, please let me know 😊 Thank you all for any help
