Yes, you can camp overnight at Loch Lomond, but it is strictly regulated by Seasonal Camping Byelaws that apply from March 1st to September 30th each year. During this period, you must stay in an official campsite or purchase a camping permit (typically around £4.30 per tent) to stay in designated "Camping Management Zones" along the loch shores. These zones were established to prevent environmental damage from over-tourism. If you are "wild camping" outside of these zones, you must follow the Scottish Outdoor Access Code, which emphasizes "leave no trace" and staying in small numbers for only two or three nights. For motorhomes and campervans, permits are also required for overnight stays in specific parking areas like Firkin Point or Inveruglas. In 2026, the National Park Authority strictly enforces these rules to protect the pristine landscape, so it is essential to book your permits online well in advance, especially for weekends, to avoid fines and ensure you have a legal and safe spot to enjoy the "Bonnie Banks" under the stars.
