The lookout tower
From Gränna hiill you have a sweeping view of Gränna and Vättern. Anyone wishing to broaden their horizons, can take a stroll along Holaveds road between Gränna-Tranås to Forest Gate, which is located about 1.5 km east of Northern Boarp.
The tower was built in 1973 on the initiative of sports journalist Torsten Tegner and is sometimes called Tegner Tower. An interior spiral staircase of 144 steps lead up to a viewing platform, which reaches a height of 351 meters above sea level (262 meters above the lake). From here you can see all the four provinces surrounding the lake: Närke, Småland, Västergötland and Östergötland.
