Kayaking on the Jordan River does not come close to kayaking on the Delaware, but it is fun, especially if it ends up in a spontaneous splashing water fight (as it did between my kids and some visiting American college boys in another raft on the river). There are basically three companies that offer kayaking on the Jordan River - Kfar Blum, Hagoshrim and Dag Al Hadan. We have used both Kfar Blum and Hagoshrim. There are slight variations on the routes (Kfar Blum has a nice plunge at the end but Hagoshrim seems to be a bit longer) but in general the experience is the same. One can take a raft which seats 6 people or a kayak which seats 2 people but requires more effort. There is an adventure expedition which is two plus hours but the standard route is approximately one and a half hours and perfect for families. The several times that we have kayaked we did not make reservations in advance though it can be packed during holidays and summer vacations.
