The tightly packed terraced Art-Nouveau buildings along the Tepla River promenade were neglected and left to crumble when the country was ruled by the Communists. Reconstructed or restored to their original glory, they are once more indicative of the old Austro-Hungarian imperial towns. What you see today is the complete facelift the city was given since 1990.
Below street level, a small and well-kept park and rose garden called Dvorakovy Sady links the huge Thermal Sanatorium to the Sadova Colonnade. There's nothing to see inside the ugly glass-and-steel giant structure of the Thermal Sanatorium but it's worth climbing to its upper terrace from where the view of the town amidst steep forested hills is spectacular. You can wander anywhere in the park among hordes of German and Russian tourists who besiege the city during long summer days. The white iron-decorated structure south of the park is the Sadova Colonnade, a daily summer venue of live band music. However, it's not the music that attracts the crowds but the hot spring water. Walk over the bridge to the shopping arcade nearby to buy a 'lazensky poharek', a teapot-shaped long-spouted cup that visitors use to sip the hot stuff. You can drink as much as you like but beware - the water may be too hot, and its taste may not be to your liking.
Continue about 100 metres further south along the west side of the river until you come across the neoclassical Mlynska Colonnade, also called Zitek's Colonnade after its designer. It is a covered 132 metres long walkway housing five hot springs, each labelled with the water temperature and the minerals present. You can fill up your cup from any spring and then parade around, cup in hand, like everyone else is doing. Before proceeding along the bend of the river, take a look at the huge bottle of Becherovka on display at the left corner of Lazenska street.
After 30 metres or so, you reach Trziste, a small square lined with numerous shops selling souvenirs and pieces of fine Bohemian crystal. Don't miss the restored Plague Column and the splendid architecture of the buildings behind it. Nearby, the Trzni Colonnade, built at the foot of the reconstructed Zamecka Tower is a lovely Chinese-style wooden gazebo dating back to 1883.
From Trziste Square, the majestic Baroque twin-belfry church you see on the east side of the river is dedicated to St. Mary Magdalene. Built in 1736, it is the work of K.I. Dienzenhofer who also designed the majestic Church of St. Nicholas on Prague's Malostranske namesti. The huge glass structure in front of the church is the 1974 Vridelni Colonnade. Ugly, misplaced and obtrusive, it is one of few buildings the town inherited from the days of Communism. Have a look inside to see one thermal spring shooting out 72 degrees hot water to a height of 12 metres. Inside, there are several other hot springs where you can refill your cup. Numerous tiny souvenir shops and the Kur-Info Tourist Office are also housed inside the Colonnade.
Continue south along a further stretch of the lovely promenade that lines the river. Along Stara Louka on the west side, several chic restaurants, splendid cafes, pastry shops and top-class hotels housed within recently restored buildings add to the architectural beauty and the lively atmosphere of the area. But no other building is more impressive than the City Theatre (Divadlo Vitezslava Nezvala) on the east side along Nova Louka. Look towards its Art-Nouveau main facade from the opposite bridge (which doubles as an open-air restaurant in summer) and admire its architecture, meticulously restored to its former splendour. Even if you're not attending a concert, ask to be allowed inside and admire its splendid interior beauty and works of art.
If you continue straight ahead, you'll reach the Karlovy Vary Museum at Nova Louka 23. There's not much to see inside but its souvenir shop is worth visiting just to have a look at the numerous unusual items on display, some of which you'll not find elsewhere. In front of the museum, the huge elegant building you see on the other side of the river houses two luxury hotels, the Grandhotel Pupp and its twin sister the Parkhotel Pupp. Even if your budget is tight, you should at least take a coffee from the hotel's elegant Cafe Pupp (entrance from Mirove namesti) or for a splurge, dine inside one of the hotel's luxurious restaurants. (See my former entry: Grandhotel Pupp.) You can even have a look at the extravagant shops and fashion boutiques housed on the ground floor of Parkhotel Pupp.
The area east of these hotels has fewer attractions since few of the buildings have yet been restored but the park is good for a stroll away from the crowds. In the park along the river promenade, you'll come across numerous busts of famous people who came here from all over Europe for daily doses of hot mineral water from the town's thermal springs. You'll meet Schiller, Liszt, Marx and the monumental bust of Goethe who paid numerous visits to Karlovy Vary.
Better and more pleasant is a stroll amidst the forested hills above the west side of the town. From an alleyway north of Grandhotel Pupp, take the Diana Funicular which rises 166 metres to the Diana Tower. From here, you can follow a network of footpaths that lead towards numerous lookout points from where the panoramic views are excellent. If you follow any trail leading east, you'll reach the colourful gazebo-style hunting lodge of Jeleni Skok (Mountain Goat Pass) while if you walk along the south trail, you'll reach the more impressive Karla IV Lookout Tower, a castle-shaped structure built as a monument to King Charles IV.
