Mozarts Geburtshaus (mozarteum.at) is a museum in the city of Salzburg housed in the building where 18th-century composer Wolfgang Amadeus Mozart was born in 1756. The room of his birth is on the third floor. Mozart's first viola and violin are on display, as are objects from his daily life. You will need about an hour to see all the exhibits, according to the museum. Children 6 years old and younger are admitted free.

An exercise in symmetry, the 18th-century Schonbrunn Palace (schoenbrunn.at) in Vienna, the Austrian capital, was the summer home of the Hapsburg rulers. Forty of the Baroque's palace's 1,441 rooms are open to visitors. Among these are the lavish state apartments, including the Hall of Mirrors, where in 1762 at the age of 6, Mozart performed for empress Maria Theresa. Equally alluring are the palace gardens, punctuated by such structures as fabricated Roman ruins and the Gloriette, a marble colonnade.

The south tower of St. Stephen's Cathedral (stephanskirche.at), a 14th-century construction, dominates Vienna's skyline. The 352-foot cathedral was restored after the Turkish siege of 1683 and again after suffering damage in World War II. The wealth of sculpture inside includes an unusual 16th-century pulpit by Anton Pilgram, with carvings of the artist, four saints and several amphibians, and a 15th-century wooden altar piece depicting the Virgin Mary. You can climb 343 steps to the summit of the south tower, known as Old Stephen Tower, or ride the elevator to the top of the much shorter north tower for panoramic views of the region. General admission is free, but there is a fee to explore the catacombs, where 56 funeral urns contain the remains of Hapsburg rulers.

Austria's oft-traveled 30-mile Grossglockner High Alpine Road (grossglockner.at) takes you past the country's highest peak, 12,470-foot Grossglockner, and the Pasterze glacier. The toll road, which has 36 hairpin turns, runs north-south between the towns of Bruck and Heiligenblut. The highest portion is within the Hoctor Tunnel at 8,225 feet. Another road, Gletscherstrasse, branches off the highway near the town of Guttal and leads to Franz-Josefs-Hohe, a lookout that affords panoramic views of the mountain. Postbus (postbus.at) offers service between the city of Zell am See and Franz-Josefs-Hohe. Due to snowfall, the Grossglockner High Alpine Road is only open from mid-May through mid-November.

Fifty-five miles west of Vienna, in the town of Melk, is Melk Abbey (stiftmelk.at), which Frommer's deems "one of the finest baroque buildings in the world," and its equally impressive church. A functioning Benedictine monastery since the 11th century, the current building dates to 1736. See the 100,000-volume library, which has a ceiling fresco by Paul Troger, and the Marmorsaal, a hall adorned with red marble pilasters. Melk Abbey is open to visitors year-round. From November to March, you can only explore on a guided tour, which you must book in advance. To get to Melk, take a train from Vienna's Westbahnhof station.
