Thanks for the mention Rick. But you will always be the reigning KING of the best hikes!
I still think the best hikes are the ones that we find out by mistakes or trial and error. The trails much less traveled…
Hi;
Thanks for your list of hikes. We live in Budapest, and are looking for a hike for the 3rd week of April this year; somewhere reasonably warm where snow on the trail will not be a problem: Italy, Greece, Spain, etc are all possible. Any suggestions? We have a week? Thanks for any thoughts.

April is early for the mountains. I’d instead consider a coastal hike in a Southern country. This one is on my mind right now:

My most favorite hike ever was Cinque Terre, Italy. It was an incredibly beautiful experience. The Rockies aren’t bad either, though. =)
