Tengo más cosas que no he encontrado, pero por si te sirve para hacerte una idea, la Lonely en inglés vienen algunos itinerarios chulos:
CITIES, CULTURE & SEASIDE (Two to Three Weeks)
Start off in the capital, Sofia ( p82 ), with its excellent museums and galleries, expansive parks and Bulgaria’s best restaurant and nightlife scene. For a complete contrast, take the train to the beautifully restored village of Koprivshtitsa ( p191 ), a stunning spot filled with gorgeous National Revival–era house-museums. It’s a peaceful spot to stay for a day or two. From here, take a bus to busy Plovdiv ( p138 ), where you can easily pass a couple of days browsing through the art galleries, exploring the Roman remains or just taking it easy at one of the many street cafés. From Plovdiv, make for the Black Sea coast and stop overnight in the bustling city of Burgas ( p213) before heading up to Nesebâr ( p229), famed for its beautiful medieval churches. Spend a few days here, maybe taking a day trip to Sunny Beach (Slânchev Bryag; p235 ) for a spot of sunbathing, then continue up the coast towards Varna ( p237 ). This city’s superb Archaeological Museum and Roman Thermae are definitely worth a visit, while the beachfront promenade has some of the best bars and clubs on the coast. Start back westwards, stopping at historic Veliko Târnovo ( p170 ) on the way; its ancient fortress is unmissable and the views fantastic. Spend at least one night here before returning to Sofia.
MONASTERIES & MOUNTAINS One Week
From Sofia, head out to Dragalevtsi ( p109 ) in Vitosha Nature Park ( p109 ),
just on the outskirts of the city. Take a peek at the much-revered Dragalevtsi Monastery, and then take the chairlift up to Goli Vrâh.
Depending on the season you can then go walking or skiing in the Mt Vitosha range, which affords some spectacular views back over Sofia, weather permitting.
The following day, take a minibus from Sofia for the short journey to Samokov ( p119 ), looking over its History Museum and mosque, then catch another minibus to Bulgaria’s burgeoning ski mega-resort at Borovets (p120 ). Again, depending on the time of year, you can either slip on your skis and take to the slopes or, in summer, go hiking in the beautiful Rila National Park ( p115 ), south of town.
After whiling away a few days in Borovets, return to Samokov for a connecting minibus to Dupnitsa, where you can get another bus to the village of Rila ( p116 ). Here you can either stay overnight in the village’s sole hotel, or else at one of the places near Rila Monastery (p117 ), just a short bus ride away. This spectacular monastery is the holiest pilgrimage site in Bulgaria, and is one of the country’s most visited attractions. Try to ignore the inevitable tour buses and snaphappy crowds and just admire the stunning wall frescoes and beautiful architecture of the place. From Rila village, you can catch a bus back to Sofia.
THE UNESCO HERITAGE TOURThis tour takes you to nearly all of Bulgaria’s Unesco World Heritage sites. Some are awkward to reach by public transport; see relevant sections for details. From Sofia, take a day trip to the suburb of Boyana, and the delightful Boyana Church ( p108 ) with its 13th-century murals. Going south, call by the splendid Rila Monastery ( p117 ) on a (long) day trip from Sofia, or from Blagoevgrad. It’s the country’s largest monastery, and a true highlight. The Pirin National Park ( p124 ), best explored via Bansko, offers numerous walking trails and remarkable scenery.
Travelling east to Kazanlâk, you’ll come upon the Thracian Tomb of Kazanlâk ( p200 ). The tomb, dating from the 4th century BC, is open to the public.
Going northwards, the impressive Ivanovo Rock Monastery ( p274 ) is inside the Rusenski Lom Nature Park, near Ruse, and the Srebârna Nature Reserve ( p274 ) is best reached from Silistra. Get a bus down to Shumen, from where it’s possible to visit the Madara Horseman ( p169 ), an 8th-century cliff carving. Finally, head to Varna, then down the coast to picturesque Nesebâr ( p229 ), the last stop on the Unesco trail.
OUTDOOR ACTIVITIESThis tour takes in most of Bulgaria’s best outdoor activities. From Sofia, head south to the Rila Mountains, where you can hike to the magical Seven Rila Lakes ( p123 ), sleeping in mountain huts along the way in summer; in winter, ski the venerable resort of Borovets ( p120 ) nearby. Further south, the Pirin Mountains also boast great skiing at Bansko ( p127 ) and vast acres of untamed wilderness for hikers.
From here continue east to Plovdiv, and drop down into the Rodopi Mountains for more hiking and some therapeutic dips in the mineral hot baths of Devin ( p160 ); Devin’s also a good base for visiting Bulgaria’s best caves, at Yagodina and Trigrad ( p162 ). Returning to Plovdiv, continue north to Veliko Târnovo, where you can arrange horse riding through rolling meadows and forests in nearby Arbanasi ( p179 ).
Continuing north, stop off at swinging Ruse on the Danube to explore the Rusenski Lom Nature Park ( p273 ), home to both rare bird species and unique cliff monasteries. Head further east along the river to reach Lake Srebârna ( p274 ), Bulgaria’s best spot for blissful bird-watching, or try your hand at fly-fishing at nearby Vetren ( p274 ).
In summer, it’s obligatory to end up on the Black Sea coast, for swimming and sailing at Albena ( p249 ) or the quieter beach at Kavarna ( p254 ).
Espero que te ayuden a hacerte una idea de un posible itinerario! para una primera vez, yo creo que una variante del 1º o el 3º estarían muy bien!
