Police have issued a warning following a number of thefts from tents and caravan awnings at campsites in Roecliffe and Scotton.
Harrogate police are advising campers and caravan owners to make sure they keep their property secure.
Thieves stole jewellery including a gold locket and a gold ring, a Toshiba laptop computer, Olympus and Canon cameras, a portable DVD player and Samsung and HTC mobile phones. They also took clothing and toiletries.
Chief Inspector John Downham, of Harrogate Safer Neighbourhood Command, said:
If you have a caravan with an awning, I am urging you not to leave anything of value in it overnight or when you are leaving it unattended. Rather, lock them inside the caravan.
People who are camping should ensure that valuables are in the same compartment as they are sleeping in.
Alternatively items should be locked out of sight, in the boot of your car.
By their nature, awnings and tents are vulnerable to opportunist thieves, who can be in and out in a matter of moments.

Anyone who can help to identify those responsible for any of the thefts is asked to contact Harrogate police on 101, select option 2 and ask for Neil Roworth. Alternatively information can be emailed to email@example.com
