Llandanwg Beach (pronounced 'hlan-dan-oog') consists of coarse sand and pebbles backed by low dunes. At the southern end is a sandy harbour, protected by a concrete breakwater, whilst to the north the shore becomes rockier. At low tide it's possible to walk along the shore to Harlech beach. Parking is at a small P&D car park with additional roadside parking available nearby, and access to the beach is along a short, straight tarmac path. Facilities include toilets ♿, drinking water and 'Y Maes' cafe, which has outdoor seating and views towards the Rhinog mountains. Llandanwg rail station (2-hourly service) is an easy 400 yard walk away. It's generally a safe beach for swimming, but rip currents can occur in surf conditions. As with nearby Shell Island, a good variety of sea-shells can be found here. Note that there is no lifeguard service at this or any other beach in the county of Gwynedd.
Dog restrictions are in operation to the left of the main access for a distance of about 300 yards between April 1st and September 30th.
Adjacent to the car park is the small 13th century St Tanwg's church, which seems in danger of being engulfed by the dunes. South of the car park is the National Trust Y Maes nature reserve, which is home to the rare Sharp Rush (Juncus acutus) - so called because its leaves end in a sharp point.
