When you're visiting a place famous for a specific dish or type of cuisine — say, barbecue in North Carolina — trying it once isn't enough. You want to sample as many versions of that pork shoulder as possible. We found 10 places around the world where it's easy to sample the local specialty — you only need to get there …
1. Portland Beer Trail
Boasting more breweries than any other city in the world (current tally sits at 51), Portland is a no-brainer for beer lovers. This drag-and-drop map makes it easy to plan your route. Highlights include:
2. Finger Lakes Cheese Trail
New York’s largest wine-producing region is also home to dozens of artisan cheesemakers. You’ll have your pick of straight-from-the-farm wheels and blocks, including French, Italian, Portuguese and Spanish-style blends. Base yourself in Wakins Glen or Geneva, rent a car, then head to:
3. Spain's Olive Oil Greenway
Nearly 20 percent of the world’s olive oil (and half of Spain’s) comes from Jaén, in Andalucia. A 34-mile trail called the Vía Verde del Aceite, or Olive Oil Greenway, was once a working railroad that transported olive oil to market. Today, the abandoned rails have been converted into walking and cycling paths that run through half a dozen small towns and into the city of Lucena — surrounded by olive groves the entire way. Bring your bike; the entire trail takes about five hours. A couple of stops along the way:
4. Kentucky Bourbon Trail
Bourbon was born in Kentucky, so you might as well go to the source for a tasting. The self-guided trail, designed by the Kentucky Distillers Association, takes visitors to six distilleries (in between Louisville and Lexington), which are easily split into two loops. In terms of transportation, a better-safe-than-sorry option is Mint Julep Tours, which operates bus tours from place to place.
5. North Carolina’s BBQ Trail
The North Carolina Barbecue Society’s Historic Barbecue Trail, which runs from eastern North Carolina down to Tennessee, features 28 of the state’s best pits. Most are down-home eateries that serve moist, tender cuts of pork, with a side of slaw and hushpuppies. You’ll need to drive between stops, so if you only have a day, your best bet is to stay in Chapel Hill — it’s the dividing line between the eastern and western styles (eastern features plain, whole-hog pork with a touch of vinegar-based sauce; western ’cue is always made from dark-meat pork shoulders with a tomato-y sauce). Three to try:
6. Louisiana's Bayou Bounty Trail
More than 15 restaurants from Lafayette to Morgan City on down to Leeville comprise this lip-smacking trail. Cajun dishes and seafood dominate, of course. What to try:
7. New Mexico’s Green Chile Cheeseburger Trail
More than 8,000 people voted for their favorite green-chile cheeseburger to make up this list of the state’s definitive dish. A few highlights from the 66 restaurants and 100 locations that made the cut:
8. Tuscany's Truffle Trail
San Miniato, a small Italian town responsible for a quarter of the country’s white truffle crop, plays host to dozens of truffle-related activities every fall, including festivals and fairs, demonstrations and special restaurant menus celebrating the fungus.
9. Maui's Upcountry Trail
Mineral-rich volcanic soil makes Maui’s Upcountry — in the central part of the island, on the slopes of Haleakala — home to some of the island’s best farm-to-table spots. Start near the sugarcane fields lining the volcano, then visit:
10. Vancouver's Sushi & Seafood Trail
It’s no wonder the city that introduced Greenpeace and the "100 Mile Diet" (a book touting the benefits of eating locally and sustainably) is also home to one of the world’s most sustainable seafood industries. Here’s where to stuff yourself:
