Poplar Flat is a developed camping area within the Goomburra section of Main Range National Park, Queensland, situated alongside Dalrymple Creek.

The site offers an open, flat, grassy setting with sunny conditions, and campers can fall asleep to the sound of the creek gurgling nearby and wake to forest birds and bell miners in the treetops.

The camping area is one of three developed sites in Main Range National Park and sits just 400 metres from the Manna Gum camping area. It serves as a convenient base for exploring nearby walking trails, including the Dalrymple and Cascades walks.

Facilities include campfires and toilets. Mobile phone coverage in the park is limited, with signals possible only from peaks or high ridges.
