The Warren is a sandy beach about 1½ miles long, extending from Abersoch harbour to the granite headland of Mynydd Tir-y-Cwmwd at the north-eastern end. It's backed by dunes and the Warren Holiday Park. Part of the shore is owned by the park and is extensively used for boat launching, but there are no access restrictions. The beach's eastern end is known as Quarry Beach and the far western (Abersoch) end is known as 'Traeth Tywyn y Fach', or more simply as 'The Fach'. Dogs are allowed at all times.
P&D parking at the Abersoch end is available in bays alongside the A499 (landward side of road) just east of the village. Beach access is then a short, sandy path through the National Trust's Tywyn y Fach property. Some (free) layby parking is available 250 yards east of the holiday park entrance, from where beach access is a public footpath through the park. For Quarry Beach, a small car park is located just behind the shore at Grid Ref : SH328303 and can be reached via some very narrow lanes around the side of Mynydd Tir-y-cwmwd. The beach looks out towards St Tudwal's islands to the south-west and the Cambrian mountains towards the east.
