20 species of reptiles occur in the park. Three species of leaf-tailed geckos (Phyllurus ossa, P. isis and P. nepthys) occur in small rainforest patches in and around the park. P. nepthys is endemic to the Clarke Range. The recently discovered orange-sided rainforest skink (Tumbunascincus luteilateralis) is endemic to the area, and is restricted to upland rainforest above 900m in moist areas which contain rotting logs and palm fronds. The skink species Lampropholis basiliscus reaches its southern limit at Eungella.
