Every year, it seems, there are more farms on the Vineyard. By our last count we’re up to thirty-eight. The FARM Institute in Edgartown and the Native Earth Teaching Farm in Chilmark are currently the most geared toward visits and tours, but many of the other farms are welcome visitors. Farm. Field. Sea. offers local food tours and culinary adventures across Martha’s Vineyard. Not every farm is open to the public, so be sure to call ahead if you want to visit.
