Most golfers find that travelling by road is the most convenient way to get around.
Being in control of your own timetable gives flexibility for extra time in the clubhouse, adding a trip to a nearby distillery (though beware the strict drink driving limits!) or other sightseeing options.
Self-drive is often the most cost-effective option but a wide range of companies offer golf transfer services, including dedicated luxury coaches with your own driver for the duration of your trip.
Scotland, including many of the golf courses, can also be explored by rail, ferry, or plane.
