A new report says more technology should be used, to help take the strain off national parks that are feeling the effects of climate change.
Researchers at Lancaster University say sensors that offer real-time information on how natural environments are coping with tourists could help.
The report - Smart Parks, has been commissioned by the Lake District National Park.
Other ideas - like bins that know when they're full, could also be used to help cut unnecessary journeys by collection wagons.
Report Author Professor Edward Truch, said: “National Parks are under increasing pressure to deliver more for less and with population booms, visitor numbers are increasing – putting greater strain on the natural environment.
"A Smart Park could open up opportunities for new types of visitor attractions, which protect rather than spoil some of the world’s most treasured landscapes.
“Visitors are already making use of intelligent connected devices through apps like Google, Ordinance Survey and Booking.com for things like navigation and accommodation bookings.
"Some areas of the world are already drastically cutting traffic pollution by introducing ‘smart’ car parking systems, for example, directing individual motorists to available car parking spaces."
