Heidelberg and its castle

Mist lifts off the Neckar as you step onto the Old Bridge and the sandstone of Heidelberg Castle warms to a soft red. You thread up via Kornmarkt, glance at the 1592 Hotel Zum Ritter, then ride the 1907 funicular to the Wittelsbach terraces. In the courtyard, the giant Heidelberger Tun points to centuries of Palatinate wine, while the Apothecary Garden viewpoint opens the skyline toward the Odenwald ridges.

Your driver collects you at your Frankfurt hotel in a Mercedes E‑Class or V‑Class and stays on hand all day—about 1h15 down the A5 with stops whenever you like. In town, you tour while they handle parking and timing, pause for lunch along Hauptstrasse, then return via the Bergstrasse (B3), a 65‑km ribbon of orchards and vines around Heppenheim and Zwingenberg. Flexibility is built in: a spur to Schwetzingen or a coffee‑and‑cake break fits smoothly into the plan.
