Hi
i am from the Uk, have already done berlin and paris and london and want to plan a 4 week trip in august. i know i can get an interail pass. this will be my first lone trip, planning to backpack, keep it cheap.

I was thinking of headin to spain, the north coast and workin my way down, maybe portuagl, or france, was even considerin andorra?

is this realistic and what would be the best places for 4 weeks? any help would be great
