When you're planning your trip to the Blue Mountains it's important to note that you can go at any point throughout the year however there may be limited recreational activities available to do depending on what time of year you travel in. For example, the months with the highest rainfall in the Blue Mountains are between February and March, and between November and December so visiting the mountain's peaks during this time is not recommended. This is due to the limited outdoor activities available, as hikes and other tours become riskier and unsafe to carry out during wet weather periods.
Having said that, there isn't a specific 'best time' to visit the Blue Mountains with everything depending on your own travel plans and what you find the most enticing about the area.
