Begin your tour with a light hike along the forested coastline not far from Tallinn. Visit an abandoned naval fortress which is tucked away in the forest, where it is still possible to explore the dark underground tunnels and the massive concrete structures above the ground. From there your tour continues to the Keila Waterfall, located in a peaceful manor park with charming bridges and walking paths. Drive through the mostly Russian-speaking city of Paldiski, getting a feel of its industrial Soviet-era neighborhoods. Following that, visit the local Russian orthodox church to learn about the contrast between Estonian and local Russian cultures. A break for lunch at a local restaurant is then provided, during which you can order Estonian food for lunch. Continue the tour to the Pakri coastal cliffs where you can observe the red lighthouse looking over the vast Baltic Sea. Whilst there, it is optional to buy a ticket to the lighthouse to climb to the top, or walk all the way to the Pakri Waterfall. For the final stop on your tour, drive to the Rummu submerged quarry. Whilst there you can climb up the sandy hills for a view over the entire crystal clear lake and the submerged houses. As you return to Tallinn, you can reflect back on your day filled with nature, alternative off-the-beaten sights, and secret history.
