Ferries
There are two scheduled boat services that connect Muck with the mainland:
The Caledonian MacBrayne ferry MV Lochnevis sails to all four of the Small Isles from Mallaig throughout the year. It calls at Muck on Monday, Wednesday and Friday during the winter; Tuesday, Thursday, Friday and twice on Saturday in the summer. Although the construction of the island's slipway and pier in 2005 now permits the boat to enter the harbour and unload vehicles via its ramp, the channel into the harbour is narrow and winter sailings can still be disrupted by bad weather.
During the summer, Arisaig Marine provide wildlife sightseeing cruises from Arisaig, about 10 miles south of Mallaig. Different islands are called at on different days, but the timetable generally allows access to Muck on days when the CalMac ferry does not.
Train Connections
If not travelling to Mallaig or Arisaig by car, you can reach the ferries by scheduled ScotRail train service although note that the pier at Arisaig is not as close to the railway as the pier at Mallaig.
The famous ScotRail 'Deerstalker' Caledonian Sleeper provides first class single cabin and standard class double cabin sleeper and reclining seat travel between Fort William and London Euston every night except Saturday. Local trains connect to Mallaig.
If travelling by day train, travelling to Muck from anywhere further south than Fort William is only possible without an overnight stop in Mallaig on summer Saturdays, when the early morning train from Glasgow Queen Street station connects with the second CalMac sailing to Muck.
Travelling from Muck to points beyond Fort William by day train is likewise only possible on summer Saturdays, when the first CalMac sailing from Muck connects with the train to Fort William and Glasgow Queen Street.
