Glencoe is a famous valley ("glen") in the ScottishHighlands and also the name of the village adjacent to the glen on the western side. It is owned by the National Trust for Scotland  and is considered one of the most spectacular and beautiful places in Scotland. It is a part of the designated National Scenic Area of Ben Nevis and Glen Coe. Loch Leven, in the adjacent area, is a salt water loch connected to Loch Linhe, a sea loch.
Glencoe is famous for its landscape - it is home to some of the most spectacular mountains in the UK. The glen is a U-shaped valley formed by Ice Age glaciation. It is about 16 km (10 miles) long with the valley floor less than 700 m (0.4 miles) wide, with towering mountains rising sharply from the valley floor to heights of around 900 m (3,000 feet).
It was also the site of the historic Glencoe Massacre that took place on 13th February 1692.
When William III replaced James II on the British throne in 1689, he offered peace, on condition of their taking an oath of allegience within a certain date, to the rebellious Scottish clans that remained loyal to the latter. The MacDonald chief dithered but arrived for submission on the last date. Some procedural wrangles followed and his opponents wanted to teach him a lesson, even though he was allowed to take the oath.
Earlier, on their way home from the Battle of Dunkeld, the Maclains of Glencoe, a sept of Clan MacDonald, together with their Glengarry kinsmen, looted the lands of Robert Campbell of Glenlyon. He was ultimately forced to take an army commission. Robert Campbell and his men were billeted in Glencoe and accepted the traditionally warm hospitality of the MacDonalds. At some point during their stay, Captain Campbell received orders to "put to the sword all under 70". Thirty-eight men were killed, and forty women and children died of exposure after the village was burnt. Some of the officers refused to execute their orders and broke their swords in protest.
The glen is virtually uninhabited.

It's a walker's area.
Glencoe museum in the village.
The new National Trust visitor centre - it gives an explanation of the geology and history of Glencoe, and also an explanation of the work of the National Trust.
The best way to experience Glencoe is to walk. Recommended walks include:
The Lost valley: A walk into a hidden hanging valley (2 hours round trip)
Buchaille Etive Moor: This is the big mountain as you enter Glencoe from Rannoch Moor
For the more experienced:
The Aonach Eagach ridge is regarded as the most thrilling scramble in the mainland UK. On the other side of the Glen are the three sisters of Glencoe and above them Stob Coire am Lochan and Bideann nam Bean. There are numerous walks on this side but be wise and find one from a guide book rather than making up you own route. Bideann has seen more than its share of accidents.
Glencoe is also an excellent rock climbing venue.
Do not forget that rock climbing is a potentially dangerous activity and it is essential to be well equipped. Advice and maps can be found at the Glencoe Visitor Centre.
