Recommendations 4 Santa Marta Area (Bogotá)

Ive been to Santa Marta once for a few days. Saw the outskirts of Tayrona Park (Planning a full day back there this time as well), Went to the museum where Simon Bolivar lived. Had dinner in Taganga. I was wondering if anyone had any recommendations of anything there or relatively close (willing to drive an hour away or so) to there that is a MUST see or do?? :) Be happy with any info! Thanks! ~Sandy
