Nature is usually free, but that’s not always the case with special places like botanical gardens. Unless it’s San Francisco when the SF Botanical Garden is free to enter all day! That’s right, if you are not a morning person (the gardens are free daily between 7:30 a.m. and 9 a.m.) and prefer to stroll into nature around noon, then this day if for you. It's open and free between 7:30 a.m. and 18:00, so you can go at whatever time you want throughout the day. You’ll get to sleep in, plus check out a beautiful park for free, all in the same day. This is one of the most diverse gardens in the world, and is located in famous Golden Gate Park. It has 55 acres of open spaces & landscaped gardens, offering an abundance of more than 8,500 kinds of plants from all around the globe!
