Here are a few pointers to other Corsica-related information:

• Christian Blum wrote a great detailed description of hiking on the GR20.
• Eric Fourchault has nice photos and some pointers to to other resources.
• Corsica on the Internet has lots of miscellaneous information about Corsica.
• Bernd Cebulski has photos and pointers.
• Cédric Lecourt has a short description of GR20 and a few pointers.
• Guy Blelloch offers more pointers.
• Finally, my own home page carries photos I took in 1994, not to mention "Back to Corsica", which you are looking at!
