Mynydd Drws-y-Coed is a peak on the Nantlle Ridge in Snowdonia, north Wales.

It is located at the easterly end of the ridge, and is a subsidiary summit of Trum y Ddysgl.

It has steep west-facing cliffs, the summit area being the highest point on a thin ridge.

[1] The west side is very rocky and airy, and some scrambling is needed to attain the summit.

A good head for heights will also be needed on the exposed regions.
