A new travel start-up with secured funding looking to attract UK tourists to the beautiful, unspoilt Greek island of Lesvos. A privately owned business, we started Real Lesvos stemming from a real passion for Lesvos for over 20 years. It is the 3rd largest island in Greece, and home to exceptionally beautiful and varied landscapes, flora and fauna. There is a huge range of things to see and do on the island, all hosted by the friendly locals. It has a relaxed, authentic and traditional feel which is hard to find, especially somewhere so beautiful. Very few UK tourists/travellers visit Lesvos, so we believe there’s a huge opportunity to provide authentic, sustainable, varied, high-quality trips to UK travellers with a personal, local feel. We believe that providing an online professional English-language resource and window to local products will make a positive impact to Lesvos, and its inhabitants and hopefully create a business that will help regenerate the local economy, which has suffered from recent financial and political crises. The first phase is to sell accommodation as an online agent. In addition, Real Lesvos will provide lots of useful information for all aspects of travel and holidays on the island. We are starting with a website with plans to expand to a mobile app.
