Handicapped people sometimes feel it's difficult to travel, especially in a country like Israel with all the historic sites and old cities. In a way, they are probably right, it is more difficult but it doesn't mean impossible. You can visit almost every site in Israel even in a wheel chair.
I have experience with these kind of tours. Indeed there are some places that are not approachable with a wheelchair, but with the right planning, and allocating enough time to move around the obstacles, you can visit Israel and see almost everything there is to see in this beautiful country.
Obstacles are there for us to overcome
