Jana Naue

Jana has been with Inselhüpfen since 2024 and supports us in the booking department. She studied tourism management in Salzgitter and, after successfully graduating, has now found her ideal career start in her first full-time position in Konstanz.

Jana joined our Booking Department in October 2022. She is happy to answer all questions from our island hopping vacationers and partners by phone or email.

‘The combination of ship & bike is simply ingenious! You get to know many places / islands in a short time all the while staying fit. This concept also avoids guests having to constantly re-pack their suitcases.’ Jana is of the opinion that you can never travel enough and it is never too late.

Pierce Cassidy

Pierce joined our Marketing Department in May 2023. He helps us to keep all important information about island hopping up to date on the internet and in the travel documents. He has always loved the travel and hospitality industry as shown by his years of experience working in Sales and Marketing for various luxury hotel brands in Canada and Europe.

Before joining Islandhopping, he had no idea that this concept of bike and boat tours existed: ‘On my first trip in Turkey, I instantly realized why guests fall in love with the concept. It is a truly unique way to explore and, in my opinion, the perfect combination of biking, exploring, swimming and time on board the ship. The concept really is one of a kind.’

Jana Harms

Jana has been supporting our Marketing Department in Konstanz since March 2024. However, her connection to Islandhopping goes back much further! As a dual student in Outdoor and Tourism Management, she experienced work as a Tour Operator in our company from 2019. In 2022, she worked as a tour guide on our ships in Croatia for the first time and enjoyed the experience so much that she returned in 2023. In her free time, Jana prefers to cycle with a tent and camping stove in her luggage. She is particularly fond of Scandinavia with its endless forests, pristine lakes and picturesque archipelago islands. There is hardly anything more fulfilling for her than setting up her tent right by the water after a long day of biking and enjoying the evening in the peaceful natural surroundings.

Max Bachmann

Max joined our office team in Konstanz in October 2023. He is studying Outdoor Tourism Management at the Lake Konstanz Campus and is completing the practical part of this exciting course with us. But even before he started his program, tourism was anything but a foreign concept for Max: he trained as a travel agent in his hometown of Leipzig and then worked as a bicycle guide in the cruise industry. This makes him a perfect fit for our team and he can now get a taste of all areas of Islandhopping’s business as part of his training. Max's motto is: "One backpack is enough for traveling!" He loves backpacking and is a real globetrotter. He particularly enjoyed the Philippines, Malaysia, Singapore and Australia.

Herbert Krummenauer

Herbert has been our business consultant, number cruncher and excel geek since 2011.
