Called the eighth wonder of the world, the canal cuts 48 miles across the isthmus. The best observation spot on the Pacific side is at Miraflores Locks, a 15-minute taxi ride from the city center. The visitors' center has four exhibition halls, a navigator simulator, interactive modules, nifty canal models and an observation deck for watching the locks in action. The visitors' center is open 9:30 am-4:30 pm with an admission fee of $8 for adults and $5 for children. The terrace and dining room overlooking the locks is open daily 10 am to 10:30 pm.
