There are several wineries south of Eugene that border each other — King Estate and Iris Vineyards are backdoor neighbors, and Chateau Lorane is also very close. I have heard anecdotally that you can walk from King Estate to Iris, and last year there was a 5K/10K trail run in the area that took the racers to all three wineries. However, I do not believe that it is an officially designated or marked trail. My suggestion would be to stop in at Iris or King Estate and ask the tasting room staff.
If you’re not looking for a hiking trail, per se, but just a beautiful route, you should definitely check out some of the routes in the Eugene area and South Willamette Valley. You can find maps and directions to guide you on scenic drives or bike rides that go from winery to winery. You could also walk these routes if you choose, but they are on roads, not hiking trails.
If you are really interested in the wine-hiking (aka “wiking!”) experience, here are a few vineyards in the Willamette Valley with hiking trails:
- Sokol Blosser, just outside Dundee: they have a guided vineyard hike you can sign up for.
- Winter’s Hill Vineyard, Dundee Hills: They’re an official stop on the Willamette Valley Birding Trail, and they have a native oak savannah you can hike through.
- Left Coast Cellars, Eola-Amity Hills, just west of Salem: They invented the term “wiking” and have a great map of trails through their property.
- Eola Hills Legacy Estate vineyard: this is just a few minutes from Left Coast and in a very pretty location.
- Tyee Wine Cellars, Corvallis: This small vineyard is on land that’s been owned by the same family for more than 100 years. Their hiking trail takes you through native wetlands, farmland, and hazelnut orchards all on their family property.
