Driftwood Bay State Marine Park is located along the southwest coast of Day Harbor to the east of Resurrection Bay, a twenty-three mile boat ride from Seward. The park's shoreline includes medium to coarse gravel and cobble beaches interspersed with steep rock cliffs. Driftwood Bay SMP, the largest of the area's marine parks at 1,480 acres, offers excellent mountain views and wildlife viewing opportunities.

Driftwood Bay SMP is a popular fair-weather anchorage for recreational boaters and offers good protection from Day Harbor's often rough seas. Fishing for saltwater fish species is popular in Driftwood Bay and Day Harbor. Fresh water is limited to runoff during wet weather.
