Just 33 miles (56km) from the capital, Sigulda is a picturesque little town located in the primordial Gauja Valley. It's well worth the trip for tourists to Riga. Dubbed the 'Switzerland of Vidzeme' due to the steep cliffs and caves that line the sides of the river gorge, Sigulda makes a wonderful base from which to explore Latvia's considerable natural bounty. Notable tourist attractions of the area include the Medieval and Turaida Castles, with the former staging an annual open-air Opera Festival in the summer. Gauja National Park is within touching distance of Sigulda, offering great activities such as walking trails and bungee-jumping in summer; and luge, bobsledding, and skiing in the winter. The town of Sigulda itself is particularly worth visiting in spring, when cherry blossoms bloom; and in autumn, where the town seems to take on the blood-orange hue of the leaves falling from its trees. Be sure to visit the Gutmanis Cave, the largest in the Baltic region, and the setting of the Latvian folktale of the Rose of Turaida.
