Henri Murison, CEO of the Northern Powerhouse Partnership, proposed the charge to improve the environment and enhance local bus services.
The suggestion follows new data revealing a 14 per cent drop in overall visitors and an 18 per cent fall in day visitors to the Lake District in 2024 compared to 2019.
Murison argued that funds raised could address underfunding in local government and provide better public transport options for visitors.
He suggested a variable charge, targeting peak congestion times in summer, with free park and ride services offered as compensation.
