Trinidad is relatively easy to negotiate on foot as most attractions are in the historic hub, centred around the Plaza Mayor. It is a charming and generally safe town for pedestrians and getting around on foot somehow suits the ponderous pace of life in Trinidad.
Playa Ancón's beaches are serviced by minibuses, usually from about 8am until dusk, running along Maceo. Taxis are available, as are car rental agencies, though streets can be somewhat labyrinthine and are known by different names which can make driving confusing. You won't struggle to hire a horse-drawn wagon either, should the urge strike you.
A novel way to explore is on the vintage
steam train, dating back to 1907, that travels to Valle de los
Ingenios. It generally leaves Trinidad at about 9.30am and returns
at 2pm. There are also popular horseback tours of the valley, and
many people get around the area on bicycles. Ultimately, it's a
small and friendly place, and exceedingly easy to get around.
