Halley, Pinecrest Gardens is a glorious, lush tropical park in Pinecrest which is in the Miami area. A visit to the park is enchanting and admission is free. You will forget you are in the city as you get lost in the winding pathways and enjoy the native flora. of course, there is always the gorgeous and well-known Fairchild Tropical Gardens. While the Gardens are not free, they are definitely worth the admission price. Every year Fairchild Tropical Garden exhibits the work of Dale Chihuly, master glass craftsman. It is an exquisite exhibition!
