Freiburg im Breisgau is a vibrant city in Baden-Württemberg, located 15km from the Rhine River and 278 meters above sea level. With 900 years of history and a focus on sustainability, it is known as Europe's solar capital. Key sights include the Gothic Freiburg Münster cathedral, which Jacob Burckhardt called "the most beautiful tower on earth" in 1869, cobblestone streets lined with Bächle water channels from 1200 AD, and half-timbered houses around the market squares. Founded in 1120 by Duke Bertold III of Zähringen as a free market town, Freiburg later grew under Habsburg rule, saw the founding of Albert-Ludwigs-Universität in 1457, and overcame many challenges, including the 1944 RAF bombing that destroyed much of the old town. Careful rebuilding brought back its medieval charm. Today, about 230,000 people, including over 30,000 students, live in Germany's sunniest city, where green innovation is a way of life. The Vauban district is a car-free, solar-powered neighborhood that generates more energy than it consumes.

Tenerife is the largest of Spain’s Canary Islands, set in the Atlantic Ocean near Morocco. The island feels like a small continent, with microclimates ranging from volcanic deserts around Mount Teide to lush banana valleys in the north and black-sand beaches meeting turquoise waves. At its center, Teide National Park, a UNESCO World Heritage Site, rises to 3,718 meters—Spain’s highest peak. A cable car ride here reveals craters in shades of ochre and rust-red above the clouds. Colonial La Laguna features 16th-century pastel mansions, Santa Cruz blends modern culture with port life, and La Orotava, surrounded by mountains, keeps Tenerife’s aristocratic history alive with its carved wooden balconies.

Estepona, nestled on Spain's Costa del Sol between Marbella and Gibraltar, enchants visitors as "The Garden of the Coast" with its immaculately whitewashed Old Town bursting with geranium-draped balconies, over 60 vibrant street murals transforming building facades into open-air galleries, and Europe's largest Orchidarium housing 1,500 orchid species beneath three glass domes—all just steps from 21 kilometers of golden-sand Mediterranean beaches. Home to 70,000 residents yet retaining authentic Andalusian charm often lost in neighboring resorts, this former Moorish fishing village balances history—15th-century Castillo de San Luis ruins, Roman mausoleum foundations, Torre del Reloj clock tower—with contemporary coastal living, its 5-kilometer Paseo Marítimo promenade linking Old Town plazas to marina yachts and Blue Flag beaches where locals still practice espeto de sardinas (sardine skewers) beachside grilling traditions. Free walking tours through the Centro Histórico unlock hidden courtyards, ceramic poetry plaques lining cobblestone alleys (Ruta de Poesía), and Plaza de las Flores' flower-framed cafés serving pescaíto frito (fried fish), while the coastal path reveals sculptor-dotted gardens and turquoise waters ideal for sunset strolls far from Costa del Sol's tourist crowds.

Santa Cruz de Tenerife sits on the northeast coast and is the biggest city in the Canary Islands. It blends modern sights with colonial history and the excitement of Carnival. The city has about 210,000 people. Its waterfront features the striking Auditorio de Tenerife by Santiago Calatrava, while palm-filled plazas like Plaza de España are busy with markets, street performers, and the smell of papas arrugadas in mojo sauce. Founded in 1494 after the Spanish defeated the Guanche, Santa Cruz became a key port for ships heading to the Americas. It defended itself from pirates, British fleets, and rival ports like Garachico, which a volcano destroyed in 1706. Today, the city hosts Europe’s second-largest Carnival, attracting 400,000 visitors, and offers modern culture at the TEA museum and Palmetum gardens. Free walking tours are a fun way to explore the city’s history, from Guanche roots to today’s Canarian pride.

Aranjuez is a UNESCO World Heritage site about 48 kilometers south of Madrid, known for its blend of royal history and beautiful landscapes. The Royal Palace, once the Spanish Crown’s spring home, stands at the center of gardens shaped by the Tagus and Jarama rivers. These rivers made it possible to create impressive gardens like the Island Garden, Parterre Garden, and Prince's Garden, each with its own style, from French Baroque to English landscape design. The gardens are filled with fountains, sculptures, waterfalls, and rare plants that reflect Enlightenment-era science. Inside the palace, you can visit 18th-century rooms such as the Porcelain Room, Arab Room, and Smoking Room, all decorated with remarkable art. The historic town center, built alongside the palace, has tree-lined streets, classic plazas like Plaza de San Antonio, and the Mercado de Abastos market. Aranjuez is also famous for its sweet strawberries and green asparagus, grown with irrigation systems that have been used for centuries. The Casa del Labrador, found in the Prince’s Garden, is a neoclassical building with silk-lined rooms and fine details from the late 18th century. The Strawberry Train, a vintage steam train from Madrid, runs on weekends from April to October and brings back the feel of 19th-century travel. With its grand buildings, lovely gardens, creative landscape design, and well-known food, Aranjuez is a great choice for a day trip from Madrid.

Avilés is a post-industrial city in Asturias, on the northwest coast of Spain. It blends impressive medieval architecture with modern design along the Avilés estuary. The Oscar Niemeyer International Cultural Centre, opened in 2011, is the only work in Spain by the famous Brazilian architect. Its white, curved buildings—an auditorium, observation tower, exhibition dome, cinema, and restaurant—stand out against the city’s industrial background. The well-preserved medieval center features arcaded streets and Plaza de España (known as "El Parche"), the city’s main square since the 17th century, surrounded by the Town Hall, Ferrera Palace, and Llano Ponte Palace. The Sabugo neighborhood, once a fishing village north of the old inlet, keeps its maritime character, distinct from the commercial area of La Villa. Gothic churches like San Nicolás de Bari and the Church of the Franciscan Fathers, along with palaces such as Valdecarzana and Camposagrado, reflect the wealth from overseas trade in medieval and baroque times. The Chapel of Las Alas, a 14th-century highlight, is open to visitors on special tours. With about 79,000 residents and a spot on the Northern Way of the Camino de Santiago, Avilés offers authentic Asturian culture, traditional cider houses (sidrerías), and easy access to beaches like Salinas.

Gijón is the biggest coastal city in Asturias, with a 1.5km stretch of golden sand and Roman history dating back to the 1st century AD. The Cimavilla neighborhood sits on a clifftop and still feels like a fishing village, with narrow streets that were once home to sailors, cigarette sellers, and fishmongers. At the top of the headland, you’ll find Eduardo Chillida’s Elogio del Horizonte sculpture, looking out over the Cantabrian Sea. Beneath the modern city, you can visit underground Roman baths and the birthplace of Gaspar Melchor de Jovellanos. Whether you’re surfing at Playa de San Lorenzo, exploring the Campo Valdés archaeological site, or tasting Asturian cider in a sidrería, Gijón offers a mix of beach life, ancient ruins, and maritime traditions—without the crowds. The city blends its industrial past with deep historical roots, attracting surfers, history lovers, and families who want to explore the waterfront on foot.

Alcalá de Henares is a UNESCO World Heritage city located 35 kilometers east of Madrid and is known as the birthplace of Miguel de Cervantes, the author of Don Quixote and Spain's most famous writer. The University of Alcalá, founded in 1499 by Cardinal Cisneros, features impressive Renaissance and Plateresque architecture and is one of Spain's oldest universities. Each year, it hosts the prestigious Cervantes Prize for Spanish literature. Calle Mayor, the city's main street, stretches nearly a kilometer and is lined with arcades, making it one of Europe's longest covered streets filled with traditional shops and cafés. The Cathedral-Magistral of Saints Justus and Pastor is a rare Gothic church with great historical importance. The Complutum archaeological site showcases well-preserved Roman mosaics, baths, and villa remains from the ancient city that came before medieval Alcalá. The Corral de Comedias, built in 1601, is Europe's oldest preserved theater and still hosts performances in its original setting. Alcalá blends literary history, university life, Roman ruins, and a true Castilian atmosphere, all just a short trip from Madrid.

Salamanca is a UNESCO World Heritage city in western Spain's Castilla y León region, known for its golden sandstone buildings that have earned it the nickname "La Dorada" (The Golden City). It is home to Spain's oldest university, founded in 1218, and is rich in academic traditions, including the famous frog legend on the University's ornate Plateresque façade. The impressive Plaza Mayor, often called Spain's most beautiful baroque square, is full of student life, tapas bars, and evening strolls under its elegant arcades. Two cathedrals, one Romanesque and one Gothic, stand side by side, showing the city's architectural history. Other highlights include the Casa de las Conchas with its shell-covered façade, the Clerecia's baroque towers with panoramic views, and the Roman bridge over the Tormes River. Just 90 minutes from Madrid, Salamanca offers a mix of historic monuments, a lively student scene, and authentic Castilian culture.

Almería is the sunniest city in Andalusia, blending Moorish history with striking desert scenery and beautiful Mediterranean beaches.

This lesser-known part of southern Spain has real Andalusian charm without the crowds. The nearby Tabernas Desert was the setting for many Spaghetti Westerns, and the Cabo de Gata-Níjar Natural Park protects unspoiled coastline with volcanic cliffs and hidden coves. Almería’s food features simple but tasty dishes like ajo colorao (red garlic stew), reflecting its farming and fishing roots.
