This is the fun bit...
Whichever way you choose to come to Jura, you'll have to cross the sea and you can do it in a variety of ways:
By Car Ferry
Book a car ferry with Caledonian MacBrayne ferries (or come over as a foot passenger) from the ferry terminal at Kennacraig to Islay (www.calmac.co.uk). The journey takes just over two hours.
You have two ports on Islay to choose from. Port Askaig is where the Jura ferry departs from or Port Ellen is on the other side of Islay and is roughly a 45 minute drive to Port Askaig.
Once you get to Port Askaig, the Jura ferry is a five minute crossing that departs hourly and doesn't need pre-booking.
You can fly from Glasgow to Islay in 35 minutes with Flybe and then either hire a car or book a taxi to Port Askaig to connect with the Jura ferry.
There is a bus service that runs from Feolin on the Jura side to Craighouse and beyond.
By Passenger Ferry
In the summer, a dedicated passenger ferry service operates from Tayvallich to Craighouse in a rigid inflatable boat and takes just over 45 minutes. See www.jurapassengerferry.com
There is one hotel on the island, The Jura Hotel (www.jurahotel.co.uk) and a handful of B&Bs. There is also plenty of self-catering accommodation. Just make sure you order your supplies before you get here...
