Yes, you can wild camp in Cairngorms National Park, but you must follow the Scottish Outdoor Access Code. Wild camping is legal in Scotland, including in the Cairngorms, as long as you do so responsibly and respect the environment. When wild camping in Cairngorms National Park, follow these guidelines:
Only camp for a short duration (usually one or two nights) in the same location.
Set up your campsite well away from buildings, roads, and other infrastructure.
Leave no trace: take all your litter, waste, and belongings with you when you leave.
Respect the privacy and property of landowners.
Avoid camping in enclosed fields with crops or animals.
Minimize your impact on the environment by using a stove rather than an open fire.
