Visit 100 UNESCO World Heritage Sites
Open the World Heritage List and the map becomes a lifetime trail: a cathedral reached by train, an archaeological landscape at dawn, a living city and a forest whose value lies in systems you cannot see from one viewpoint. UNESCO recognises cultural, natural and mixed properties for outstanding universal value. Decide what a visit means before you begin, especially for large landscapes and serial sites, then record what you experienced rather than collecting names from nearby roads. Use the official list, group nearby places into lower-impact journeys and check each site's current access, conservation rules, permits and community guidance. Avoid treating fragile or overcrowded places as targets that must be reached regardless of local conditions. Count it complete after one hundred genuine visits documented with a note about why each place matters. Add it if you want a long challenge that changes how you understand heritage, not merely how many pins appear on a map.
