Situated adjacent to canal developments and vessel moorings off the northern side of Broadwater Ave., is the mangrove boardwalk in Phil Hill Environmental Park. Built in 1997 by the Gold Coast City Council and the Runaway Bay Lions Club, the boardwalk took 1200 man hours to construct. The walk maybe joined either via a paved footpath from the park under the bridge, or from a footpath on northern side of Broadwater Ave. The boardwalk is well maintained, around 1.5 m wide, and offers good access for wheel chairs. The walk follows the exposed edge of the mangrove community where adjacent to the southern end there is a fore dune with associated vegetation. At the northern end there are views of the Coomera River and Coomera Island with the DPI&F Coomera Fish Habitat Area. Two or three small creeks flow from the creek (canal) under the boardwalk at high tide.
There appears to be revetment works (dumping of rocks), weed invasion and erosion causing mangrove felling and dieback in places – particularly along the southern end.
