Heidelberg Activities Through the Seasons
What you can do in Heidelberg shifts with the calendar. Spring and autumn suit hill walks, summer brings late light and one big fireworks night, and winter turns the Old Town into a market. Here is how the year breaks down.
Spring: March to May
Spring is the time for the Philosophenweg, a path of roughly 2 km on the north-bank slope that looks across to the castle. Reach it by the Schlangenweg, whose cobbled switchbacks stay wet and slick for much of the season, so choose shoes with tread. From 29 March the Schwetzingen palace gardens move onto summer hours, open until 20:00, with entry at €9 for adults. Weisse Flotte cruises begin to appear on its calendar, with a 90-minute Highlight cruise listed from 27 March 2027 at €29.
Summer: June to August
The zoo is open from 09:00 to 19:00 between April and September, and the main-season adult fare is €16. The Königstuhl above the castle is the cooler option on hot days. The Panoramaticket, at €17 return for adults, covers the whole funicular and the castle admissions, and the upper section alone is €10 return. Summer’s big date in 2027 is Saturday 10 July, the first of two castle illuminations. The second is Saturday 4 September.
Autumn: September to November
Autumn is quieter at the castle, which stays open daily from 09:00 to 18:00. The Studentenkarzer keeps its summer hours of 10:00 to 18:00 until the end of September, then switches to 10:30 to 16:00. On the Königstuhl the Märchenparadies amusement park closes for 2026 on 11 November. Leaves on the steps of the Himmelsleiter make the roughly 1,200 stone steps especially slippery at this time of year.
Winter: December to February
The Christmas market runs from 23 November to 22 December 2026 on six Old Town squares, with an ice rink on Karlsplatz. The zoo drops its adult fare to €13, and it closes at 13:00 on 24 and 31 December. The castle shuts on 25 December. The Studentenkarzer is closed from 24 December 2026 to 11 January 2027. The funicular has a maintenance shutdown early in the year, so look at its timetable before planning a January or February summit trip. Weisse Flotte keeps a 50-minute mulled wine cruise from €22 through winter.
Year-round tickets
The castle ticket is €11 for adults and €5.50 reduced until 31 December 2026, then €12 and €6 from 1 January 2027. The HeidelbergCARD adds travel across the VRN area for €25 a day, €36 for two days or €40 for four, with free entry to the Studentenkarzer, University Museum and several other museums.
