Situated in the heart of the Trossachs National Park, Loch Lomond is the largest loch in Great Britain by surface area. It's also one of the country's most popular destinations for boating, kayaking, and other watersports; visitors can take a relaxing cruise, head to the southern end of the loch to have lunch, go shopping at Loch Lomond Shores, or paddle around the loch's 30 islands, one of which is home to a colony of wallabies. Boaters should be aware that a 10 km/hour speed limit is enforced on some parts of the loch due to environmental concerns.
