Start your day with one of Hamburg's most popular landmarks: The grand Church St. Michaelis, also called "Michel" (subway line 3, get off at "Rödingsmarkt" or "St. Pauli").
Climb the stairs or take the elevator to the top of the church, and get your bearings from here; find the harbor, it is your next destination and only a 10-minute walk from here.
Walk to the harbor and stroll along the pier, also called St. Pauli Landungsbrücken ("landing bridges").
If you are interested in old sailing ships, pay a visit to the museum ship "Rickmer Rickmers", built in 1896.
Take a harbor boat tour from the pier, a unique way to see one of the world's largest working harbors.
Take a walk through Hamburg's 100 year old underground Elb-Tunnel, situated at the western end of the pier. Opened in 1911, this historic landmark is 0.3 miles long; it brings you to a small island where you can enjoy the spectacular view of Hamburg's cityscape.
Head back to the pier and walk to the historical warehouse district, the world's largest warehouse complex, situated just past the subway station "Baumwall".
The 100 year old warehouses with their signature red brick stones and steeped gables store coco, spices, and silk. Don't miss the light projections that start in the early evening and create a magical atmosphere on buildings, bridges and canals.
For dinner, head to the excellent seafood restaurant Rive.
No trip to Hamburg is complete without hitting the Reeperbahn, the center of Hamburg's nightlife and home to the legendary Red Light District (Metro stop "Reeperbahn"). Stroll down Hamburg's most famous street lined with greats bars, international restaurants, theatres, and nightclubs.
Visit the clubs where the Beatles played in the 1960s; the Indra Club and the Kaiserkeller are located in a side street called "Große Freiheit".
