Assuming you travel when it is possible and safe to do so.
Elizabeth, in your previous post you mentioned staying in Colmar for nine nights then onto Eguisheim. Eguisheim is only about 7km from Colmar but I guess you have your reasons for the change. This part of the world is best explored by car, with which you can also see parts of the Black Forest. If you are stuck on public transport, I believe buses go from Colmar to Eguisheim, Riquewhihr, Ribeaville and Kaysersberg. I liked them all. Train to Strasbourg and Basel. Not sure about Freiburg.
We also stayed in Riquewihr, for three weeks with a car, and did lots and lots of walking (none in the vineyards around Eguisheim). Riquewihr has many walks in the surrounding vineyards and woods, one of which is the walk mentioned above by Laurel (you’ll come across a team of large spotted pigs if you are lucky). Off the top of my head, the 3 castles in Ribeauville, the six village route starting from Riquewihr, two different paths from Riquewihr to Kaysersberg (vineyard and steeper forest route), the woods around Château du Haut-Kœnigsbourg, vineyards around Bergheim (great little place). Plus parts of the Black Forest.
The only place we ate in Eguisheim was at Caveau Heuhaus. It was the best of the Alsatian bacheofe (stew) which I tried. The décor is way up my street.
