This trolley runs between Homestead-Everglades National Park- Biscayne National Park in Florida. I met this excellent park ranger/ trolley guide 4 out of the 6 times I took this trolley in the area. She was full of information and facts about the area and extremely helpful. She told us what to do in the park, best places to eat and had an answer for every question!! As someone who doesn't drive, I love when National Parks have public transportation. I wish more parks added such trolleys.
