This was a cool tour especially for those who love science and nature. Seeing the formations is amazing and hearing the history of how they were discovered and formed is so mesmerizing. If you are afraid of the dark, water dripping on your face and enclosed spaces, this is not the tour for you. The film at the opening of the tour is especially informative explaining how the island of Barbados was formed. We took the tram and it's not a long tour at all so it's not a full day. You can definitely plan other activities on the same day.
