I went on Birthright years ago, so I don’t remember all the places we went. Here are some of the ones I do remember:
Yerushalayim – we walked through the old city, obviously went to the Kotel, as well as the tunnels under the Kotel.
Tzfat – they took us to some of the old shuls there
Dead Sea
Masada
Golan
Tel Aviv
Yad Vashem
Mt. Herzel
Jaffa – we went to a big shuk there
T’verya
Kibbutz Lavi
We also went to help out one day by going to a center which collects items for poor families. We sorted out clothing by gender and size, and helped arrange various appliances into different categories.
Overall, I had an amazing time, and would recommend the trip to others. Just make sure you choose the right trip organizer, as most of them are not for frum Jews.
