The scenic part of the tour including Perdicaris Park and Cape Spartel was beautiful. You might skip the Cave of Hercules and save the $8 entry cost (only Moroccan cash accepted). Back in Tangier, our guide knew the medina and kasbah very well and gave us a great feeling for its many narrow streets and shops. You may wish to ask him to abbreviate this part since we found it quite lengthy, and skip the normal stop at a friendly spice merchant to sniff (and sell) local spices. There are a moderate amount of steps up and down and length, so those with mobility concerns may ask for a shorter route or earlier pick-up point.
