Plaza de los Coches, a vibrant gateway to Cartagena's Old Town, is freely accessible on foot for all visitors, including those with mobility aids, though crowds can be dense. While it can be explored independently for 15 minutes to an hour, a guided tour offers valuable historical context about its significance, including the iconic Clock Tower and the nearby Portal de los Dulces. The plaza is open year-round with no seasonal restrictions, though the dry season (December to April) provides more comfortable weather. There is no cost for entry, with expenses limited to souvenirs, snacks, or optional guided tours and carriage rides that often originate here. It's a prime spot for people-watching, enjoying street performers, and sampling local sweets, but be prepared for bustling activity.
