Young Judea programs are available in many cities, and a Gap Year program exists as well to travel to Israel.

The programs are run in English. But, my the passion and love for Israel and desire to infuse and use Hebrew is there in these programs.

There are a lot of Israeli families participating in these groups Nation wide, the program appeals to 2nd generation families in N. America. The focus is a fun, often outdoors, celebration of Israel and its a great way for 3rd-12th graders to learn about Jewish and Israeli culture with friends.
