If your trip to Douglas is all organized but your travel itinerary is looking a bit empty, we can give you a helping hand.St. Nicholas Abbey and Animal Flower Cave are awesome attractions that all travelers should make time to swing by. Plan out a route and spend a few hours taking in each one.Close to the city center, Mullins Beach is one attraction you might like to consider adding to your to-do list. Heywoods Beach and Gibbes Beach are also a stone's throw away and worth a pit stop.
