The #SlowTravelSpain campaign will recognise the "importance of forming a connection" with local people and cultures when travelling, while lessening harmful impacts on communities and the environment.
The campaign will focus on geographical diversification and aim to showcase low-impact activities and journeys that fit within the "slow travel" theme.
The tourist board said taking part in low impact activities, exploring quieter routes and travelling with seasonality in mind will provide visitors with a "more authentic experience" of the country.
