Cycling is a European success story tells the first heading of the Declaration on Cycling as a climate friendly Transport Mode. Over the last decade, cycle­tourism has increased exponentially in Europe, both in terms of infrastructure & service and public attendance. The cycling tourism industry generates an annual turnover of €44bn. It represents nowadays a strategic priority for many territories in Europe mostly due to its potential for attracting added­value tourism. Cycle-­tourism has clearly taken substantial advantage from the extended urban mobility developments based on bicycle. New populations of cyclists are claiming for new experiences brought by new models of sustainable tourism. This is also extremely challenging for territorial management and land­use planning since Cycle­tourism represents a powerful opportunity to provide infrastructures and create services and employments in remote areas. In that sense, natural heritage could deeply benefit of cycle­tourism. Many territories in Europe are characterized by extended natural heritage. Growth is always subordinated to the strict evaluation regarding preservation of biodiversity and ecosystems at risk. We remind that the EU2020 strategy fostering sustainable environmental development and an efficient use of resources is mandatory for taking off green and competitive economy. Therefore, ECO­CICLE aims that bicycle becomes the official sustainable transport to access natural heritage while fostering endogenous economical revival through a popular modality of tourism. In order to determine the best conditions to develop cycle­tourism in natural heritage context, ECO­CICLE builds on the experience of the partnership, especially on our advisory partner ECF. Main objective of ECO­CICLE is to improve operational programs and regional development policies to allocate SF and other investments funds(about 50M€ is targeted through 24 new projects) in infrastructure and support to cycletourism service providers.
