Embarking on an Interrail journey with my girlfriend was incredible! Here are some tips: plan for at least three days in each place to enjoy it fully. Nature walks were amazing - they let us relax and connect with the outdoors. Staying with friends or family saved time and gave us a local experience, museums were great for learning about history and art, and catching early trains gave us more time to explore. Visiting five countries gave us a taste of different cultures. Train stations were busy, so be ready for crowds. Overall, it was an unforgettable experience that taught us to plan well, enjoy nature, value personal connections, explore culture, and be ready for the hustle of travel. Trust me, an Interrail trip will leave lasting memories!
