Rothrist combines a range of natural landscapes with local history and an indoor and outdoor swimming pool. The municipality is located in the canton of Aargau, in the Zofingen district on the Aare, and borders the canton of Solothurn. When planning your visit, it is worth considering the highlights individually: floodplains and pond landscapes, the Langholz nature forest reserve, the local history museum and the Stampfi Baths each have their own appeal.
Nature among forests, ponds and the Aare
The Langholz nature forest reserve covers 23.84 hectares. It was rewetted to restore the moist to wet forest habitats characteristic of the area, providing a home for rare animal and plant species. Common toads and dragonflies, among others, live there. Langholz therefore represents a different natural environment from Rothrist’s pond and floodplain areas: its focus is on moist forest habitats and their restoration.
The Hölzli Weiher nature reserve is located in Hungerzelg, between the railway line and the Aare, and covers 94 ares. Its ruderal area includes a large pond and two pools, edged by a hedge and the Aare’s riparian vegetation. A variety of wildlife species have different connections to the area: reed warblers and moorhens breed there, and beavers are regular visitors. Wall lizards, sand lizards and grass snakes have settled in the area, and numerous dragonfly species are also found there.
The Boniger and Längacker floodplain zones are part of the Floodplain Protection Park. Their landscape features include two wooded islands, a peninsula and a shallow-water zone. At low water, shallow banks are exposed. Two reed beds are 80 and 400 metres long, and the floodplain strip also measures 400 metres. The zones provide numerous waterbird and wader species with food, resting areas and nesting opportunities. These features give the floodplains a different character from Hölzli Weiher, with its ruderal area and two pools.
The Canyon also shows how varied aquatic habitats can be. Together with the adjacent pond, it forms a stepping-stone biotope and a wildlife corridor between the railway embankment and the Aare. At the Canyon, beavers have transformed the deep ravine into a still-water body by building two dams. Reed warblers breed at the pond, which is also home to Alpine newts and green frogs. Those interested in Rothrist’s natural environment will find a range of described habitats and relationships between species here, not just a single pond landscape.
The local history museum and the history of the town
The Rothrist local history museum is housed in a farmhouse dating from the 19th century. Period-furnished rooms can be seen on two floors, while the attic presents the history of Rothrist. The museum covers farming life, emigration and industrialisation, and features special exhibitions. The house therefore focuses both on everyday life and on broader changes in the town’s history.
One particular historical perspective is the emigration to America in 1855. The museum documents that 12 percent of the village’s population left Rothrist or were forced to leave at that time. Both aspects—leaving and being forced to leave—are equally part of this account. The place names also mark different points in time: Niederwil was first mentioned in a document in 1242, and Rothrist in 1262. The municipality’s name was changed from Niederwil to Rothrist with effect from 1 January 1890.
The construction of the railway was also historically significant for the municipality’s development. The opening of the Aarburg–Herzogenbuchsee line on 16 March 1857 encouraged numerous industrial businesses to settle in the area and helped Rothrist prosper. This development adds a specific date to the topics of industrialisation and village history covered by the museum.
The local history museum is usually open on the first and third Sunday of each month from 2:00 to 5:00 p.m. It was closed in July and August 2026. As opening hours may change seasonally or according to the programme, it is advisable to check them before visiting.
The Stampfi Baths as another highlight
The Stampfi indoor and outdoor swimming pool complex includes an indoor pool, an outdoor pool and a sauna. This combination allows it to operate throughout the year. As a family-friendly swimming complex, Stampfi offers plenty of opportunities for leisure, sport and relaxation. The baths therefore complement Rothrist’s nature and culture attractions with a distinct focus on swimming and exercise.
