Opera Festival of Tuscany

Florence, Italy (9-29 Jul)

The Boboli Gardens behind the Pitti Palace are the main location for Italy's newest opera festival. Built for Eleonora di Toledo, wife of Cosimo de Medici, these formal 16th-century gardens are lined with grottos, nympheums, fountains and temples.

Since 2004, a temporary stage in the gardens has been the focus for opera and other large-scale musical events during the Florence festival. This year, performances of Verdi's Aida and Rossini's Barber of Seville will be interleaved with a concert double bill of Bolero and Carmina Burana, plus ballet from Roberto Bolle and a concert by singer-songwriter Claudio Baglioni. The festival could continue into August, though dates are yet to be confirmed.

The location: As well as the Boboli Gardens and the Pitti Palace, this side of the Arno (known as Oltrarno) is rich in sights including the 16th-century palazzos Guadagni and Bianca Cappello; Brunelleschi's last church, Santo Spirito; and Casa Guidi, where the Barrett-Brownings lived from 1846 to 1861, after their secret wedding.

Grafenegg Music Festival

Grafenegg, Austria (20 Aug – 6 Sep)

In 2007, the distinguished Austrian pianist Rudolf Buchbinder launched this music festival just outside Vienna. Schloss Grafenegg is a moated castle belonging to the Metternich princes. The festival has a policy of giving carte blanche to its artistes over what they perform, so this year we have Sir Colin Davis conducting the LSO in Sibelius's Fifth Symphony, Kristjan Järvi conducting the resident orchestra in Carmina Burana, and the festival's composer in residence, Tan Dun, premiering a new concerto for stone and ceramic instruments. The castle's old riding school is used for chamber concerts and there is also an open-air arena in the landscaped gardens.

The location: Grafenegg sits between the Wachau and Vienna, an area with a rich history of wine-growing. There is a good scenic route out of Vienna via the baroque Stift Klosterneuburg church and Krems, with its 13th-century Gozzo palace and late-Gothic Piaristenkirche.

How to get there: Donau Niederösterreich Tourismus (00 43 2713 30060; grafenegg.at/enjoy/accommodation/ packagesteigenberger) offers two nights at the Grafenegg festival from €255 per person, based on two sharing, including B&B and tickets to two festival performances.

Tartini Festival

Piran, Slovenia (28 Aug – 12 Sep)

In 2002, the first festival to celebrate the neglected works of Giuseppe Tartini (1692-1770) was held in his home town of Piran. The festival was the idea of local musicians Jasna Nadles and Milan Vrsjakov, who invited international baroque music experts to join them in playing the works of Tartini and his contemporaries – composers such as Bach, Telemann and Vivaldi. The festival uses various locations around the town but mainly the cloister of the Convent of St Francis.

The location: When Tartini was born, Piran was part of the Venetian Republic. Underdeveloped after Napoleon destroyed Venetian independence, Piran fossilised. Today, it is a large open-air museum of medieval and Renaissance buildings – and full of tourists. Architectural highlights include Tartini Square, the municipal palace, the judicial palace, Tartini's house, the Cathedral of Saint George and the town walls.

How to get there: The Kempinski Palace Portoroz (00 386 5 692 7000; kempinski.com) offers two nights at the Tartini Festival from €640 per person, based on two sharing, including B&B, use of the spa, and tickets for two festival performances.
