9 days help

Direct flight from Montreal to Panama City . I have 9 days max and not sure how to go about my itinerary this time . I would like to do a couple day jungle trek . I did one in Thailand and Costa Rica and would love to do it again . If you have any recommendations I would appreciate it . also not that expensive . If I did a trek from Panama City that would take up 4 fill days . So 4 days left it seems . I don't know how far I should come venture to ??? what are you opinions on my time frame and places of interest I could see . Thanks a lot TA
