We're 2 persons (Canadians) planning to do the Malaqi trail on either October 15th or October 16th. We have rented one of the chalet and would really like to do this trail. As you may already know, they need a minimum of 5 persons. The best place to get information is definately the RSCN website which is the ''official'' website for all the Reserves in Jordan.
