GRTgaz is one of urope's leading natural gas transporters and worldwide expert in gas transmission networks and systems.

In France, GRTgaz owns and operates 32.300 km of underground pipelines and 27 compressor facilities to carry gas between suppliers and customers (manufacturers or distributors directly connected to the transmission network). Major player of the energy transition, GRTgaz invests in innovative solutions to adapt its network and to reconcile competitiveness, supply security and environmental protection.

In Provence-Alpes-Côte d'Azur, GRTgaz employs 105 employees between Aix, Cagnes-sur-Mer, St Martin de Crau, Volx, Aubagne and Septèmes; they operate a network close to 1.600 km which irrigates nearly 300 municipalities. GRTgaz thus holds public service responsibilities for the transport of more than 20% of the energy consumed by the region.

With a network located, for the most part, in rural or forest areas, GRTgaz has registered natural heritage preservation at the heart of its social and environmental responsibility (SER) charter. Since 2010, GRTgaz has developed many partnerships with regional parks to promote the preservation of biodiversity around its network.

The presence of over 200 km of pipelines in the regional natural parks of the Region has naturally led GRTgaz to take a new step in its commitment in supporting the actors of the Chemin des Parcs, an innovative initiative which allows the combination of leisure and the discovery of natural resources of our lands. 

EDF, partner of the touring network of Verdon

To meet the growing need for electrical power and water, the dams and power plants of Castillon (1948) and Chaudanne (1952) were built on the upper valley of Verdon.
Then in 1963, the power plant located in Vinon-sur-Verdon and the dam in Gréoux (1967) were built on the lower valley of Verdon. The centrepiece has been the construction of the reservoir of Sainte-Croix-du-Verdon (1974): with 761 million m3 of water over 2.200 hectares, the reservoir has contributed to the impounding of one of the most important mountain lakes. Finally, Quinson (1974) completed the development of Verdon.
The 5 EDF hydroelectric power plants in Verdon produce, on average, the electricity needed for 195.000 people per year.
They are considerable assets for the region and contribute to water sharing:
• drinking water supplied to 3 million households,
• irrigation of 120.000 hectares of farmlands,
• industrial water supplied to 440 companies,
• limitation of drought and floods,
• development of the tourist economy.
EDF is also the land administrator on which are concluded right-of-way contracts to promote the development of the touring network of hiking around the Verdon lakes.

Vélo Loisir Provence has had one goal for the last 21 years: to develop the attractiveness of cycle tourism, closely cooperating with the territory and with regional parks, particularly.  To achieve this, the association aims to develop and coordinate a network of tourism professionals, structured around a Charter setting out the main lines of the brand “Accueil Vélo” (quality of the reception, the equipment, the related services and the information) to ensure appropriate and quality services to cycling tourists. The association also promotes the creation of itineraries, ensures the promotion and maintenance of some, still in connection with the regional national parks (RNP), the Communautés de Communes et d’agglomération, the County Councils and the Region of Provence-Alpes-Côte d'Azur.

Vélo Loisir Provence ensures that its actions comply with the tourism and sustainable development standards, namely:
• a long-term activity ecologically acceptable, as well as viable and economically equitable from an ethical and social point for the local population;
• an activity that is intended and controlled locally as a tourism promotion for encounters and sharing, drawing its arguments in the richness of the terroirs and the friendliness of the people;
• a dynamic of initiative and local management with direct economic impact towards the municipalities, while highlighting the natural and cultural heritage.

It is therefore natural that Vélo Loisir Provence collaborates on defining and planning the bike routes proposed on

The Conservatoire du littoral buys large properties as sometimes small plots, in the coastal towns but also around the metropolitan lakes of more than 1000 ha. If the intervention around the lakes, since the origin of the Establishment created in 1975, is less known, it pursues the same objectives: preserve virgin spaces from all urbanization, natural and agricultural landscapes and, as far as possible, to the benefit of the greatest number of people. The reception is then organized according to environmental issues and users, often farmers, who ensure the management. Lake Sainte Croix, with an area of ​​2,200 hectares, justifies the application of the littoral law and therefore the intervention of the Conservatoire du littoral. the Conservatoire is investing in the partnership aimed at structuring the roaming offer, including the Sainte Croix Lake tour, which runs through the Conservatoire properties. This partnership enhances the value of heritage resources and enhances the interpretation of landscapes recently transformed by the impoundment of the lake.
