Comox Sandhills represents an ancient sand dune system in the Comox Valley near Cape Lazo, British Columbia. The dunes have been overgrown by a forest of Douglas-Fir and Shore Pine, which are joined by Western Hemlock, Western White Pine, Sitka Spruce, Western Red Cedar and Red Alder in moist areas. Classic podzol soil profile development was the rule, mapped as Kye-Custer complex ("Ky-Cu") in a 1959 survey; however, housing developments have since disturbed the area and disrupted soil profiles so that many of the soils no longer resemble podzols. As a result, a 1985 report mapped the Sandhills in a brunisolic (Kuhushan) soil association.
The Sandhills lie east-northeast of Comox town center. Most of Lazo Road east of the junction with Guthrie passes through the Sandhills. Housing developments along Kinnikinick Road, Sand Pines Drive and Sierra Pine Road are among those on the old dune system. The northeast boundary lies near and roughly parallel to Knight Road. Lazo Wildlife Park protects the northwest corner of the dune area.
