The best way to take a tour and visit an assisted living facility is to call them and schedule a time to do so. It is not recommended that you just show up without reaching out first, but any good facility would be able to accommodate you if you choose to do so. Calling ahead ensures there will be someone there who can answer your questions and show you around their center. Most facilities have someone dedicated on doing just that and they usually do this during certain times to ensure it fits in with the activities and events that are occurring at the center. So, for the best experience, reach out and set a time to speak with someone who can do this for you or your loved one.
