If you’ve already visited Israel, you know that the hospitality is legendary. Everyone, it seems, has a friend or cousin somewhere that you should look up. But they aren’t the only people who will welcome you. The entire country is host to “visitors centers” from north to south, from the Golan to Ashkelon, that invite you to learn, taste and explore the Holy Land’s resources. In fact, Israel boasts a wide range of these open houses, including spots of historical importance, as well as “foodie havens” for award-winning beer, wine and olive oil. While these sites are open to the public year-round, some of them offer special activities during holiday periods, so check their Web sites before your visit for the most up-to-date information.
