Loch Lomond features a colony of wallabies on Inchconnachan island, introduced by Lady Arran in the 1940s.
The loch is crossed by the Highland Boundary Fault, separating the geological regions of the Scottish Highlands and the Central Lowlands.
Inchmurrin is the largest freshwater island in the British Isles and once housed a 7th-century monastery and a later castle.
The loch contains deep underwater trenches reaching depths of up to 190 meters in the northern basin.
It is the primary water source for Glasgow, with an aqueduct system built in the 19th century still in operation.
Loch Lomond is the largest inland stretch of water in Great Britain by surface area, spanning 27 square miles within the Loch Lomond and The Trossachs National Park. The loch sits directly atop the Highland Boundary Fault, which creates a distinct geological division between the Lowlands and the Highlands. It contains over 30 islands, including Inchmurrin, the largest freshwater island in the UK, and Inchconnachan, which hosts a feral population of wallabies. The water serves as a major hub for recreational boating, kayaking, and open-water swimming. Several companies operate passenger cruises departing from Balloch and Luss. The West Highland Way long-distance walking trail follows the loch's eastern shoreline for several miles. Ben Lomond, the southernmost Munro, rises steeply from the eastern bank to an elevation of 974 meters.

Use the ferry services to reach the islands, as many are otherwise inaccessible.
Pack waterproof gear regardless of the forecast due to rapidly shifting Highland weather.
Utilize the designated 'Loch Lomond Byelaws' zones if planning to bring your own motorized craft.
Attempting to hike Ben Lomond without proper hiking footwear or mountain navigation skills; relying on mobile data in remote northern areas.
Cruise services run more frequently during the summer season and are significantly reduced or limited during winter months.
Practice 'Leave No Trace' principles; keep dogs on leads near livestock, and refrain from camping in prohibited 'management zones' without a permit.
