This out and back track is in the Boodjamulla (Lawn Hill) National Park in the remote north-western part of Queensland, near to where it gives way to the Northern Territory. The park contains Lawn Hill Gorge and the Riversleigh World Heritage Site, part of the Australian Fossil Mammal Sites. The fossil deposits here are among the most extensive and richest in the world, with some dating back 25 million years!The trail can be accessed from the car park in the Lawn Hill Gorge section of the park. Take the path from here to the visitor centre, then take the Rainbow Serpent Track to the trailhead of the Constance Range Track. The path runs alongside the Lower Gorge and up onto the ancient sandstone ridges of the Constance Range. The views here over the black terrain of the Gulf Savanna Plains are expansive and breathtaking and silence reigns. Immerse yourself in the delights of nature; listen for the shrieks and cries of kites as they circle above and lookout for wallabies and wallaroos as they go about their lives on the escarpments.The trail is 2.3 miles and is graded as Medium. For information on how we grade trails, please click here. Also, check our latest community posts for trail updates. It will take around an hour and a half to complete the trail, although caution is advised on trail times as this depends on multiple variables.

Also be aware that there is no drinking water available on the track so top up at the visitor centre or Lawn Gorge Camping area beforehand; don't drink water from Lawn Hill Creek as it contains very high levels of calcium carbonate.
