Early this fall, I was searching for a European vacation that offered interesting sights, exceptional food and lodging, and the opportunity to be outside and active during the day. I chose a walking tour of the Tuscany countryside with a small company called Tre Laghi Travel (2627 Lombard St., San Francisco, CA 94123; telephone  777-8183.)
I was not disappointed. Our group of nine people was treated to heavenly destinations and we stayed at country estates, town villas and rustic farmhouses. Every meal was excellent. The walks ranged from eight to 10 miles a day, and all trips are owner-led.
