Travel to the island
By Train
You can buy a special SailRail train & ferry ticket between any rail station in Britain and Douglas on the Isle of Man. See this site.
By Road
There are roads but since it is an island you will need a ferry to get your vehicle over the wet bit.
By Air
Commercial flights use Ronaldsway.
It is also GA friendly but there is also the private airfield at Andreas which is PPO.
By Sea
Ferries dock in Douglas.
If you have your own boat Laxey is on the coast and has a harbour
