Input: Question: In what country are the Caha Mountains? Passage:Starting at Glengarriff, the Beara Way enters the Glengarriff Woods Nature Reserve and then climbs into the Caha Mountains to an altitude of as it traverses the pass north of Sugarloaf mountain before descending to reach the village of Adrigole. From Adrigole, the trail follows the southern flanks of Hungry Hill and the Slieve Mish Mountains to reach Castletownbere. A spur route makes a circuit of Bere Island, which is connected to Castletownbere by a ferry service. The route from Castletownbere to Allihies is via an old cattle droving path. Copper mining was the main activity in Ahillies for many years and the remains of abandoned mine working dot the landscape. Another circular spur route starts from Allihies and brings the trail to the very tip of the Beara Peninsula where a cable car connects the trail with Dursey Island. From Ahillies, the trail follows a miners' track and climbs the copper-rich crags above the village, crossing a mountain pass to reach Eyeries. A ridge along the coast connects Eyeries with Ardgroom. The trail then crosses into County Kerry to reach Tuosist, via Lauragh. From Tuosist, the Way crosses the northern slopes of Knockagarrane and then passes between Clonee Lough and Lough Inchiquin before crossing a mountain pass. The route diverges here, continuing north to Kenmare or south to Bonane. The final stage returns to Glengarriff via Bonane Heritage Park and Esk mountain. A spur route connects Glengarriff with Kealkill, Gougane Barra and Ballingeary.
