Llanrhystud Beach: (SN 525 691) g Parking area at road end on at the top of the beach.
Aberystwyth harbour south: (SN 580 807) g Parking area at top of shingle beach at south end of harbour. Launch either into harbour (drop boats near sailing club nearby) or on the beach. The harbour dries at low water.
Aberystwth Harbour North: (SN 580 809) g Slipway just inside the breakwater, plenty of parking nearby.

Tywyn: (SH 579 001) g Small car park with slipway nearby onto beach.
Fairbourne: (SH 610 136) g Gravel car park a short carry from the beach, to the north of the village.
Barmouth slipway: (SH 615 155) g The large beachfront car park may be a long walk from the sea except at high water. It may be better to drop boats by the slipway at the harbour. The harbour dries completely, but launching should be easy 2 and a half hours either side of local high water.
Penmaenpool Bridge: (SH 693 184) g Car park just to the east of the south end of the bridge. Launching easiest at a field 200 south west of the hotel, where there is space to drop boats off. There are also stone steps to the water in front of the hotel. The George III hotel bar is recommended.
Barmouth Beach*: (SH 614 155) g The bay below the Bath House Cafe has enough water to launch 2 hours either side of high water, below which the harbour area dries to sand. There is a large car park, the south end of which is by this beach.
Porth Aberamffra*: (SH 622 157) g Old harbour with slipway, usable 2 hours either side of high water, dries to mud. Avoids fast water under the Barmouth Bridge. Parking area on opposite side of road.
Penrhyn point, Fairbourne*: (SH 615 147) g Parking area popular with camper vans by a beach and slipway. Usable 2 hours either side of high water.
Llanelltyd*: (SH 718 193) g Car park with height barrier on the south side of the old bridge (space to drop boats outside of barrier). A footpath leads from the road into a field west of the south end of the bridge. This area and the adjacent gravel spit are used as a bathing spot in summer and might be used for launching. However, the river will only be navigable to this point (the tidal limit) on the largest tidal ranges. Watch out for tidal streams around the wooden pilings of the toll bridge 3km downstream.
Barmouth Marine Parade*: (SH 608 161) g Parking along Marine Parade by the long sandy beach. Surf can form here. Be wary of groynes north of this point.
Bartmouth North Promenade Car Park*: (SH 603 172) g Large car park. North end offers options for access with a ramp down to the sea (beach at lower tides) and a beach to the north (all tide levels).
