Zoo By Moonlight is an evening event held at Heritage Park Zoological Sanctuary every full moon from May through September. It is a great time to see the Sanctuary's nocturnal residents out and about that you may not see during the day. To walk the park by moonlight and hear the howling of the different animals - it really is a very unique event! Docents will also be available to help locate animals and answer questions. Cost of attendance is $4 for Members and $6 for Non-Members.
