This is a free trolley that runs every day from 10am-2pm every day from Memorial Day to Labor Day. We didn’t know what to expect, but we learned so much about the history of Trinidad. The guide made the city come alive for us and very patiently answered any questions. It was full on a Sunday afternoon, so plan ahead. The tour was about 1.5 hours long and ended with the gorgeous artwork in the Trinidad Hospital. The tour is worth it just to see that. They do accept donations, so bring a little bit of money, because after this tour, you will definitely want to contribute to the efforts to keep the history of Trinidad alive.
