Salterstown Pier is a small coastal launch point in County Louth, located approximately two and a half kilometres from Annagassan Port. The pier offers a straightforward put-in for small boats, with a parking area directly adjacent. Coordinates for the site are 53.87766, -6.30101, and it can be located by searching "Salterstown Pier" on Google Maps.

The area is tidal, and the tidal range is considerable — at low tide, large expanses of flat stony beach and rocky shoreline are exposed, with the water receding a significant distance from the pier. Paddlers should plan launch and retrieval times around the tide, as access to the water at low tide requires navigating rough terrain. Patches of seaweed on the rocks present a slip hazard when moving gear to and from the water.

The surrounding seascape offers views across to the Cooley Mountains and the Mourne Mountains. The shoreline supports a varied mix of gulls, terns, and shorebirds during summer months, with the area appearing to be a productive feeding ground for waders and wildfowl in winter. Species observed in the vicinity include curlew, oystercatcher, little egret, and various gull species.

The access road to the pier is minor and quiet, and the broader area is rural in character.
