If you want to cover the two main attractions of Tallinn, it's romantic Old Town as well as the nature and greenery outside the city, then this day trip from Tallinn is for you.
Start the day with a drive outside the city and have a hike to experience the vast open landscape and unique environment of Estonian bogs. Admire the contrast between the yellowish-golden bog plants and the bog pools that, on a sunny day, have a perfect reflection of the blue sky and clouds above. Enjoy the surrounding silence and take time out from the rest of the world for a while.
Once you have filled your lungs with clean fresh air, get back to Tallinn where the morning rush has calmed down, leaving the streets more empty and easier to travel through. Take a guided 1.5-hour tour on the Old Town sightseeing tour, covering all the main attractions, and learn about the history of Estonia from Medieval times, Russian and Soviet periods, all the way to nowadays. Explore the cobbled streets and colourful houses and enjoy the view over the red rooftops from the viewing platforms.
At the end of the tour, you can opt to stay in the Old Town or be taken back to the Cruise Terminal.
