Alpannonia is a cross-border alpin and panorama hiking trail which binds the Eastern-Alps with the Pannonian-plain. In the programming period 2007-2013 a successful ETC project was implemented related to this issue. Unified board- and sign-system, start-gates with overview map were established, besides that at some points of the trail ecotouristic infrastructure was expanded in order to enhance attractiveness. Touristic service providers along the trail were also involved in the project. As a result of these developments hikers and nature-lovers could “sense” this unique offer in Europe but its national and international publicity was really low. The main goal of the project alpannonia plus is optimizing and expanding the hiking trail based on common conception, creating a long-term actuation strategy to the whole hiking-destination, quality assurance of the trails and qualification of touristic service providers by common created criteria in favour of sustainable green tourism. Improvement of touristic products and services will be implemented by providers and experts with mutual know-how-transfer and intensive cooperation. Hiking guides will have specialized education. New communication platforms will be established in order to help with standing the competition on the international market of ecotourism. In some settlements infrastructural developments will be carried out to satisfy the basic needs of hikers and to make the trail more attractive. On the operative level of the project settlements, touristic service providers and nature parks will benefit. The number of locals, day-visitors and long-trail hikers who resort to new attractions and resting places will increase. Innovative products (hiking all year, hiking & health, winter hiking) their promotion and merchandizing will insure economic growth in the project area. Through all of these the number of visitors and overnights will sustainably increase so the regional providers will economically benefit.
