Benbecula is sandwiched between North and South Uist, now all interconnected by stone causeways. In days gone by these islands were separate and crossing were made over the mudflats only at low tide. The island has some lovely sandy beaches, including a long stretch just below the airport runway. The island's economy is probably somewhat dependent on the airport and military base at Balivanich. Partly as a result of this, Benbecula is home to 1800 people which makes it relatively densely populated. Due to its central location in the island chain, it is an ideal base if tourists wish to spend several days or a week exploring North and South Uist. Local transport includes planes, buses, ferries, car hire. All sorts of tours are available.
