When is the best time to visit Katoomba and the surrounding Blue Mountains region?

The best time to visit Katoomba and the surrounding Blue Mountains region is during the spring, when temperatures are pleasantly warm but rainfall hasn't peaked. Summer gets a bit of rain, which can put a literal damper on outdoor fun, and while winters are relatively drier, they can be cool and snowy. If you do come in winter, try to plan your visit to coincide with the annual Winter Magic Festival to see the entire town transformed into an outdoor performance venue.
