Visit the start of the GR20 on Corsica. Planning a potential hike on past of the main route. The paths appear clear and well marked. The heights are way above what I am used to- more like the alps.

We swam in the shallow rapids and sprang over large rounded bolders. It seems easy from here. The choice of routes is wide, from 2 hours to over 6. There is an 18km route that that includes a 2300m summit and a long ridge walk. Could take ten hours., but the return is long and follows  easy valley terrain.
