By car it will take you about 3 hours from Canberra and 2 hours and 40 minutes from Sydney. If you are arriving from the direction of Sydney, Katoomba and Lithgow, the last section of the road into the Jenolan Valley is very windy and narrow. Therefore, it is one way into Jenolan, 11:45AM-1:15PM everyday, to allow coaches to enter safely on the narrow road. Visitors can still leave Jenolan during these times - via the Oberon Road.
Campervans are fine, but the road is unsuitable for caravans and trailers. There are caravan parks in Lithgow and Oberon, where you can leave your trailer.
Normally there is plenty of free parking. However, on long weekends, such as Easter, allow extra travel time and book ahead. Please do not take pets into the Jenolan Reserve, as it is a National Park.
Coach companies in Sydney and Katoomba go to Jenolan Caves daily.
