There is but for the life of me I can't remember how much. I know it wasn't very much.

Bonsoir, Nous avons visité cette grotte petite mais fabuleuse hier 23/08/2017 en famille. Le prix est de 28 ils / adulte et 14 ils pour les jeunes de 5 à 18 ans...ça vaut vraiment le détour...les stalagmites et les stalactites sont mises en valeurs par un éclairage approprié. De plus, un guide vous accompagne par petit groupe d'une 20aine de personne et vous explique l'évolution géologique. Bonne visite Fabien ZENOU

Its probably under an hour - but to be exact i would use google maps and check

The easiest would be to take a taxi to the Soreq Caves ("Maarot HaNetafim"). They have official entrance fee and guides there. The tour starts every 30 or 45 minutes. Very good - small but nice!

It is a pretty low key place, so I don't think they would have wheel chairs for rent at the location itself. It was strenuous with a lot of stairs to get from the parking lot to the entrance. Perhaps there was another path I didn't see. The path within the cave is dark and has a stair or two. Maybe you would take a little flashlight to help him keep his footing?

Yes it is, Indeed, I visited the place in shabbat,
