The Ardnamurchan Peninsula (Scottish Gaelic: Àird nam Murchan: headland of the great seas) is in the Scottish Highlands. It's the most westerly and remote part of mainland Britain, accessed only by a long, winding single-track lane. For visitor purposes the name generally applies to the entire triangle of land west of Loch Linnhe, north of the Sound of Mull, and south of the A830, taking in Moidart, Sunart, Ardgour and Morvern as well Ardnamurchan which geographically is just the western tip.

Strontian is the tiny village at the centre of this triangle which gave its name to the element strontium. In 1790 geologists discovered a new mineral in the lead mines here, which they called "strontianite", and within it identified strontium from its distinctive crimson-red flame. It became commercially important in the 19th C in the extraction of sugar from beet, and in the 20th C for the coating of TV cathode-ray tubes; nowadays a major use is for red firework flares. It's chemically similar to calcium and is therefore taken up by bones and other body tissues. The natural isotope is mostly strontium-88, which is non-toxic, radio-stable and not a health concern. It's strontium-90, a radioactive product of nuclear fallout such as the Chernobyl explosion, that causes bone cancer, leukaemia and other serious conditions. You're not at heightened risk of these through visiting Strontian.

Get in

The nearest railway stations are in Fort William and Oban, and you need a car to get in and around this remote place. The usual approach is by A82 through Glencoe and over Ballachulish Bridge to the little ferry at 1 Corran, then follow the lane south to Strontian, Lochaline and Kilchoan. The ferry, which saves a long detour around Loch Eil, is run by Highland Council. It runs M-Sa 06:30-21:30 every 20 mins, Sundays from 08:30 every 30 mins, £8.20 per car for the five-minute crossing. No booking, just turn up and queue.

Another route from Fort William is to take A830 west past Glenfinnan, branching south at Loch Ailort. This road leads to Moidart, Acharacle, Salen and Kilchoan. See under Mallaig and Fort William for buses and trains along the Glenfinnan stretch.

There are two Calmac ferry routes from the Island of Mull: between Fishnish (by Duart Castle) and Lochaline, and between Tobermory and Kilchoan. A ferry also runs across the outlet of Loch Sunart between Drimmin and Kilchoan.

Get around

You need a car. Ardnamurchan's few buses are timed for school run and shopping trips and similar errands to Fort William, with one bus there in the morning and one bus returning mid-afternoon.

Shiel Bus 506 runs Mon-Sat between Kilchoan and Fort William, via Salen, Acharacle, Strontian and the Corran ferry, taking 2 hours 30 mins. The eastbound bus leaves Kilchoan around 08:00, connecting with the ferry from Tobermory. The westbound bus leaves Fort William at 13:50.

Shiel Bus 502 runs Mon-Sat between Acharacle and Fort William via Moidart, Loch Ailort and Glenfinnan, taking 90 mins. It's basically a school bus for Lochaber High School, with the eastbound bus leaving Acharacle around 07:00 and the westbound bus leaving Fort William at 15:30; it doesn't connect with the 506.

Shiel Bus 507 is mostly just a school bus from Drimmin via Lochaline to Strontian. On Thursdays only, it runs from Lochaline at 09:30 via Argour and the Corran ferry to Fort William, taking 80 mins, and setting off back at 14:50.

See

• 1 Ariundle Oakwood, PH36 4JB (above Strontian). Oak forests once cloaked the Atlantic coast from Norway to Portugal; Ariundle is a rare survival in Scotland, designated as a National Nature Reserve. Both sessile and pedunculate oaks (plus hybrids) thrive here; their presence is partly artificial, as they were cultivated for charcoal during the lead-mining era (hence their multiple stems, from coppicing). There are two trails through the woods, which can be combined into a 3-mile loop; watch out for otters, pipistrelle bats, wildcats, pine martens and badgers. The woods are also notable for mosses, liverworts and lichens. Trails starting from the Oakwood go up to the old lead mines and the summit of Sgùrr Dhòmhnuill, a Corbett of 888 m or 2913 ft. Free. (updated Dec 2018)
• 2 Castle Tioram. A ruin on a tidal island on the shore of Loch Moidart. You can't go in, but can stroll around whenever it's low tide. 
• 3 Ardnamurchan Lighthouse, PH36 4JB. April-Oct daily 10:00-17:00. It's not quite the most westerly point on the British mainland, as Corrachadh Mòr half a mile south just edges it, but it's still a spectacular view over the roiling Atlantic. The tour includes ascent of the 36 m high tower. Adult £7.50, concs £5.50. (updated Dec 2018)
• 4 Ardnamurchan (Adelphi) Distillery (on the road between Salen and Kilchoan). Tours and other spirits available, Tu-Sa 10:00-17:00. It produces single malt whisky, but as it was only started in 2013, the whisky is still maturing and is not yet on sale.  
• Glenborrodale castle & gardens (between Salen and Kilchoan). Currently closed and up for sale. 

Do

• Scuba diving: preferably in a dry-suit, though you can get away with a chunky wet-suit in summer or early autumn. Lochaline has a dive centre, with the signature dive being along the wall near the slipway. The Sound of Mull is littered with wrecks, many of historical interest. The dive centre has a bunk-house and occasionally runs archaeological dives on protected sites where diving is normally restricted, such as the Swan, a Cromwellian warship lost in a storm in 1653; prior booking is essential.

Go next

• The island of Mull is just south across the Sound, by ferry from Lochaline or Kilchoan.
• Go north to Arisaig or Mallaig for boat trips round (or longer stays on) the Small Isles.
• Ferries from Mallaig ply to Armadale on Skye, or drive the longer way around by the bridge. The scenery is spectacular but it'll feel very crowded and touristy after Ardnamurchan.
