The swimming lake with its shady spots, a roughly two-kilometre forest loop and the pilgrimage sites give Hainburg its distinctive character. When planning a stay, it helps to first decide what you want to focus on: swimming, outdoor activity, or a visit to the religious and astronomy-themed sites.
Swimming Lake and Seasonal Planning
The swimming lake in Hainburg’s Klein-Krotzenburg district reopened on 10 May 2026. Check the seasonal information for your travel dates before making firm plans for a day of swimming. The sunbathing lawn offers plenty of shady spots. Next to the large lawn is a sandy area with various options for sports activities. This makes it possible to plan the day around different priorities: relaxing on the lawn or being active on the sand.
Two Paths, Two Themes
The “Tree of the Year” trail begins in the Klein-Krotzenburg forest at the Tannenhof restaurant. The loop is about two kilometres long and follows the Speckweg and Kapellenweg past the Liebfrauenheide pilgrimage church. The approximate distance offers a guide for planning your day; the named starting point and the route along two paths also help you get your bearings.
The Planetary Path in Hainburg’s Hainstadt district offers a different theme. It illustrates the distances and sizes of the planets in the solar system. The starting point is at Bächsteg, where a glowing sphere marks the Sun and the beginning of the tour. The paths therefore differ mainly in what they offer: the “Tree of the Year” trail leads through the Klein-Krotzenburg forest and past a pilgrimage church, while the Planetary Path illustrates the proportions of the solar system.
Pilgrimage Sites and Religious Places
A Pietà is venerated as a miraculous image in the small forest chapel at Liebfrauenheide. The Liebfrauenheide pilgrimage church is also one of the local pilgrimage sites; the “Tree of the Year” trail passes by the church. Ten major pilgrimages take place each year from May to October, including the main pilgrimage and the Fatima pilgrimages. If you are travelling for a particular pilgrimage, check the date in advance.
Another religious treasure is the small wayside shrine in Klein-Krotzenburg. The small sandstone structure has a niche for an image of the Virgin Mary. The Gustav Adolf Church is also in Klein-Krotzenburg, at SchleusenstraĂźe 17, on the corner of Friedrich-Ebert-StraĂźe. These places offer visitors a range of cultural points of interest, from a small shrine to a church and a pilgrimage site.
Nature Conservation and Cycling Route
The Pechgraben nature reserve near Klein-Krotzenburg covers 34.77 hectares and includes land in the Klein-Krotzenburg district of the municipality of Hainburg. For visitors who want to explore the surrounding nature as well as the trails and pilgrimage sites, this protected area is another notable part of the local landscape.
The Main Cycle Route runs through Hainburg along the Hessian stretch of the Main. Those considering the town as part of a cycling trip can choose this approach instead of taking a single loop or visiting the lake. Check the current route before your trip when planning your ride.
Plan Excursions Around Your Interests
Planning considerations vary depending on your priorities: the forest loop has an approximate length, the swimming lake is seasonal, and the specific date matters for the pilgrimages. For a cycling trip, you should also check the latest information about the Main Cycle Route.
