For an 8 day trip to Colombia, should I do something like Medellin, guatape, salento, Finlandia, Santa Marta, tayrona? Would I need to rent a car or fly in between? Or are there buses?

Can you help plan the exact itinerary? How would I get around to these places? Should you rent a car or no? Should I do all of these or only some?
