You can charter a boat and go island hopping, travel by ferry, drive, cycle, or take public transport.
Driving is the popular choice, especially for those staying on the main islands. You can bring you car with you via ferry, or engage car hire providers in the Outer Hebrides. With the causeways, it is possible to drive across the Outer Hebrides, save for two sections where you will be required to take a ferry: Harris to Berneray and Eriskay to Barra. Remember to drive on the left, and watch out for cyclists!
Speaking of cyclists: like a car, you can bring your own bicycle if you wish, or simply hire one. The tranquil landscapes and quiet roads of the Outer Hebrides are perfect backdrops for your cycling adventures.
Bus: There are no Sunday bus services and evening routes are rare even in Stornoway, but buses cover most areas in the day from Monday to Saturday.
Taxis: Taxis are available on the main islands, and some operators even provide tours.
