The island and its adjacent skerries are owned and managed by the National Trust for Scotland (NTS), and are run as a farm and conservation area.
The Caledonian MacBrayne ferry MV Lochnevis sails to all four of the Small Isles from Mallaig throughout the year. It calls at Canna on Tuesday, Thursday and Sunday during the winter; daily except Tuesday and Thursday in the summer.
If not travelling to Mallaig or Arisaig by car, you can reach the ferries by scheduled ScotRail  train service along the West Highland Railway (although note that the pier at Arisaig is not as close to the railway as the pier at Mallaig).
The famous 'Deerstalker' Caledonian Sleeper provides first class (single cabin) and standard class (double cabin) sleeper and reclining seat travel between London Euston and Fort William every night except Saturday. Local trains connect to Mallaig.
If travelling by day train, travelling to Canna 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 Canna.
Travelling from Canna to points beyond Fort William by day train is likewise only possible on summer Saturdays, when the first CalMac sailing from Canna connects with the train to Fort William and Glasgow Queen Street.
Vehicles are not permitted on the island. Canna is 7 kilometres (4.3 mi) long and 1.5 kilometres (0.9 mi) wide, and most easily explored on foot.
The National Trust for Scotland is the only provider of accommodation on the island.
