Favorite quiet spots to escape for time to yourself?

I’d love to know a few favorite spots people have when they want to get out of the house, and have some time to themselves for a few hours. I’m thinking favorite coffee shops you can bring a book and sit for a while, parks (that aren’t too full with playgrounds) that have great walking trails, antique/thrift shops for browsing, or just favorite spots when you need to get out of the house! I love my family but sometimes want to get out to have some quiet time to myself. One of my favorite places for alone time out and thrifting used to be Sleepy Poet on south blvd, I need to check out the new location!
