Les Platons, highest point of Jersey and the Channel Islands
Les Platons is the highest point on the island of Jersey, rising about 136 meters (446 feet) above sea level. Located in Trinity parish, the hill features gentle slopes leading to its summit, where radio transmitters and a radar station sit among open grassland and scattered rocks.
In the 1950s, Les Platons became the site of Jersey's first television transmitter, bringing BBC broadcasts to the island for the first time. During the early 1960s, FM radio broadcasts began from here, and the facility was later built with protective underground bunkers reflecting Cold War concerns about communication network security.
Les Platons takes its name from French, referring to the flat shape of the hilltop. Visitors and locals use this high point as a place to pause, look out across the island, and feel connected to Jersey's landscape in a simple, direct way.
The hill is accessible by gentle walking trails that lead through open fields, making the climb straightforward for most visitors. Clear days offer the best views across the island and out toward the coastline, so plan your visit when the weather looks fair.
The underground bunkers at Les Platons were built with Cold War protections to keep the broadcasting facility safe from possible attack. These hidden structures are a surprising link to a tense chapter in European security history that few visitors know about.
