Agreed. Racket is from a particular school of thought, and you won't get all Lisp family ideas from it, but it's great.
You can start up DrRacket (a simple IDE for students that can also be used for professional work, and has some powerful features in it), or just use your favorite editor and the `racket` command-line program and REPL. There's way too much documentation at: https://docs.racket-lang.org/
You can also do the old MIT introductory CS textbook, SICP, using Racket.
