Amsterdam's canal-woven core is laced by atmospheric narrow lanes. You never know what you'll find: a tiny hidden garden; a boutique selling witty, stylised Dutch-designed homewares and fashion; a jewel-box-like jenever (Dutch gin) distillery; a flower stall filled with tulips in a rainbow of hues; an old monastery-turned-classical-music-venue; an ultra-niche restaurant such as an avocado or strawberry specialist or one reinventing age-old Dutch classics. Fringing the centre, post-industrial buildings in up-and-coming neighbourhoods now house creative enterprises, from art galleries to craft breweries and cutting-edge tech start-ups, as well as some of Europe's hottest clubs. When the temperatures soar in Amsterdam, sun-seekers flock to the Dutch coast and the beaches at Bloemendaal and Zandvoort to bask on the sands and soak up the vibrant nightlife. Amsterdam's main attractions include its historic canals, the Rijksmuseum, the Van Gogh Museum, the Stedelijk Museum, Hermitage Amsterdam, the Concertgebouw, the Anne Frank House, the Scheepvaartmuseum, the Amsterdam Museum, the Heineken Experience, the Royal Palace of Amsterdam, Natura Artis Magistra, Hortus Botanicus Amsterdam, NEMO, the red-light district and many cannabis coffee shops. It drew more than 5 million international visitors in 2014. The city is also well known for its nightlife and festival activity; with several of its nightclubs (Melkweg, Paradiso) among the world's most famous. Primarily known for its artistic heritage, elaborate canal system and narrow houses with gabled façades; well-preserved legacies of the city's 17th-century Golden Age. These characteristics are arguably responsible for attracting millions of Amsterdam's visitors annually. Cycling is key to the city's character, and there are numerous bike paths.
