Course
Idlewild Creek begins near the northern border of Clifford Township, at the foot of a mountain. It flows southwest for a short distance before entering a wetland and turning west. Upon exiting the wetland, the creek turns southwest for several tenths of a mile, entering Lake Idlewild, where it receives an unnamed tributary from the right. From the southern end of the lake, it flows south for a short distance before turning southeast for a few tenths of a mile. The creek then enters a wetland where it receives an unnamed tributary from the left and turns south. After several tenths of a mile, it receives another unnamed tributary from the left and passes near another wetland, turning south-southwest for more than a mile. The creek then turns west for a short distance before reaching its confluence with East Branch Tunkhannock Creek.

Idlewild Creek is approximately 5.1 mi long. The creek joins East Branch Tunkhannock Creek 7.50 mi upstream of its mouth.
