Reciprocal Offers



Take your Maryland Zoo membership with you for savings on entry to participating zoos and aquariums all over the country!

ReMEMBER to pack membership cards when traveling, as more than 150 zoos, museums and aquariums offer Maryland Zoo members half price admission.  Please note that the list may change during the year, and it is always best to call a participating zoo while planning a visit.  Most of the institutions will allow up to two adults and two children, or one adult and three children in for 50% off, but charge normal admission for additional guests beyond that number.
