Mynydd Enlli

Rising to 167 metres on the holy island of Bardsey, this Marilyn offers a rugged, coastal character. The terrain consists of steep, wind-swept turf and rocky outcrops. Reaching the summit provides a sense of isolation and grandeur that belies its modest elevation, serving as the highest point on the island.

• •The name Mynydd Enlli translates from Welsh as "Mountain of the Island in the Currents," referring to the treacherous and powerful waters of the Bardsey Sound that separate the hill from the mainland.
• •The summit offers a sprawling panorama of the Llŷn Peninsula, with the distant silhouettes of the Eryri (Snowdonia) peaks, including Yr Wyddfa, visible across Caernarfon Bay on clear days.
• •The hill overlooks an island known as the "Island of 20,000 Saints"; in the Middle Ages, three pilgrimages to this site were considered religiously equivalent to a single pilgrimage to Rome.
• •While standing at just 551 feet, its classification as a Marilyn—a hill with at least 150 metres of prominence—proves that a summit's character is defined by its stature relative to its surroundings rather than raw altitude.
