As you can see in the picture below you can visit most of Israel – even if you cannot walk.
Most sights are wheel chair and scooter accessible and have special paved paths.
Even the Old City of Jerusalem and the major religious sights there are accessible in 2-3 days touring.
Tourist cars are allowed to enter relatively restricted places with while carrying special-aid people.
All hotels have rooms especially adapted to limited mobility tourists. Most restaurants and shops are accessible.
In a day’s touring – it is possible to do about 60-70% of what regular walking people will do in a day.
Hand pushed wheel chairs/scooters are available here – Electrical engine chairs and scooters too. You can bring your own. Make sure your scooter/wheelchair is adaptable to the Israeli current – 220V. See this post for scooter and wheel-chair rentals
There are guides with special vans with lifts for heavy wheel chairs and most places have elevators/ramps. Light scooters and wheelchairs can be taken in most guides mini-vans.
Most of this is due to the large amount of invalided soldiers from all our wars and very strict laws making sure they can get everywhere.
Below you can see Joyce touring here in October 2010. We went everywhere. See her post all about her experience here in the fan-mail on my page About me and my tours.
