Creek Provincial Park is a small 63-hectare park straddling both sides of Highway (19A) between the south end of Mud Bay and Deep Bay on Vancouver Island.
Rosewall Creek is an important winter habitat area for waterfowl and shorebirds. Adjacent Mud Bay is a shallow tidal bay with extensive mudflats exposed at low tides. At its south end the bay deepens slightly and broadens into a tidal lagoon, part of the Baynes Sound wetlands complex. Rosewall creek meanders along the eastern side of the bay and empties into the sound over a broad delta of silt deposited primarily during peak winter run-offs.
