Visitor Tips: Travel & Accommodation in Haut-Martelange
- Prefer public transport (buses to Haut-Martelange / Leekoll) or carpooling; parking with shuttle service is usually available.
- Bring weatherproof clothing and sturdy shoes – the historic site can be uneven and mine tours take place underground.
- Book accommodation early in the Rambrouch / Martelange area or check camping options, as the festival is popular.
- Mine visits and special performances often require on-site sign-up at the info point – arrive early.
- Embrace the sustainable and inclusive spirit: use reusable tableware and enjoy the relaxed, community atmosphere.
