Glenarm (Gleann Arma), the oldest village in the glens, has been the family seat of the MacDonnell family since 1750; the present 14th Earl of Antrim lives in Glenarm Castle, on a private estate hidden behind the impressive wall that runs along the main road north of the bridge. The castle itself is closed to the public, except for two days in July when a Highland Games competition is held, but you can visit the lovely walled garden, which opens in May with its annual Tulip Festival.
The tourist office is beside the bridge on the main road. It has internet access for £2 per 30 minutes.
Take a stroll into the old village of neat Georgian houses (off the main road, immediately south of the river). Where the street opens into the broad expanse of Altmore St, look right to see the Barbican Gate (1682), the entrance to Glenarm Castle grounds. On the left is Steensons, a designer jewellery workshop and visitor centre where you can watch craftspeople at work.
Turn left here and climb steeply up Vennel St, then left again immediately after the last house along the Layde Path to the viewpoint, which has a grand view of the village and the coast.
