The Old Bridge (Stari Most) in Mostar is a UNESCO World Heritage site and a symbol of the city, dramatically arching over the Neretva River. While the bridge itself has steps and uneven surfaces, making it challenging for those with mobility issues, the surrounding area is mostly accessible. A solo visit is perfectly feasible, allowing you to explore at your own pace, though guided tours offer valuable historical context. The peak tourist season is during the summer months, which can mean larger crowds and higher prices for accommodations. Expect to spend a few hours exploring the bridge and the surrounding Old Town. Costs are relatively moderate, with options available for various budgets.
