The Cape May Zoo is a wonderful free zoo in Cape May that is open when it rains. You will want to wear your rain jackets and carry an umbrella as not every area is covered. However, many animals act differently in the rain, so while some may be hiding away, you will still get to see many animals doing amusing activities as they play in the rain. One visitor loved that she got to see bears eat apples and romp around on a rainy day, and she loved even more that the experience was free! One of the best perks of visiting the Cape May zoo on a rainy day is that the zoo will be very empty so you and your family will feel like you have the whole zoo to yourself. Totally worth it even if you get a little bit wet.
