Fond memories of Claremont with my wife of 27 years when she was in grad school. It’s definitely a little oasis. If you ride or run there are great trails heading up Mt. Baldy. The ride up gets you up to around 5,000 feet. It’s a quick ride. Really nice up there on a hot smoggy day. That is the downside of the inland empire, but it’s a great spot nonetheless.
