Roadbook

1. Bremgarten old bridge start · 386 m

   Bremgarten is a medieval town on a bend, and the bend is the whole point. The river Reuss, fast, green and cold from the Alps, loops in a tight horseshoe here, and the old town is built inside the loop, on a spur of land that makes it nearly an island. Its medieval lords chose the site for its defensibility and built walls, gates and towers around it. Some of the towers still stand, and steep lanes run from them down to the water.

   The old bridge is the place to start. It is a covered wooden structure, roofed and enclosed, of the kind Switzerland is famous for, and it crosses the Reuss in a few wooden spans, with the pale green water below. Swiss covered bridges were roofed to protect the timbers from rain and snow, which extended their life by decades, and this one is one of the most photogenic. The view back from the far bank, with the old town stacked above the river, is the one on the postcards.

   The ride here lies in the low hills of the Freiamt, a gentle region of farms, orchards and beech woods on the edge of the Swiss Plateau, a country of cherry trees in April and a patchwork of crops in summer. Roads are quiet, curving and well maintained, and the main hazard is farm machinery. The Reuss valley has a wetland reserve of floodplain forest where kingfishers and beavers live, and a cycle path runs along the river. At 386 metres, the climate is mild, and fog often fills the valley on autumn mornings.

   Bremgarten has fuel and shops, being a town of about six and a half thousand, and the old town has bakeries and cafes. The classic Aargau treat is the Rüeblitorte, a carrot cake with almonds and marzipan carrots on top, and it goes perfectly with a coffee on a terrace by the river. Visit on a weekday if you can, since weekends bring cyclists and walkers. The bridge itself is closed to motor traffic, so leave the bike in the parking areas outside the old walls and walk across.

2. Staffelegg ridge road pass · 621 m

   The Staffelegg is a modest pass, 621 metres, but it deserves more credit than the number suggests. It crosses the folded ridges of the Jura between the Aare valley at Aarau and the Fricktal beyond, and the road that climbs it from Küttigen is one of those quiet Swiss crossings that locals use daily and visitors rarely notice. That is its charm.

   The Jura here is a landscape of long, tilted limestone ridges, like waves frozen on their way to shore, with beech and pine woods on the slopes and neat farms in the folds between. The Staffelegg road follows one of those folds. Climbing from Aarau, it winds through woodland, with corners that tighten gradually and then relax into flowing bends along the ridge. The surface is generally excellent, the signage clear, and the gradient gentle enough that even a loaded tourer feels no strain. On the far side the road dips toward Densbüren and then down into the Fricktal, a region of orchards and cherry trees that explode into white blossom in April.

   Traffic can be heavy at commuting hours, as the pass is a practical shortcut, and some drivers take it fast, so ride with some patience on weekday mornings and evenings. Weekend afternoons are easier, and the best light is in the evening, when low sun picks out the ridges and the fields glow. In winter, expect frost and occasionally snow, but the road is cleared quickly.

   Küttigen, with its five thousand residents, makes a good base for fuel and a quick coffee, and Aarau, just down the road, is a proper city with all services. Aarau is worth a short walk if you have time: its old town has painted gables and wide eaves, and it was briefly the capital of the Helvetic Republic in 1798, a footnote of history that most visitors miss. Between the city and the pass there is also a good chance of seeing red kites circling over the fields, a bird that has made a notable comeback in Switzerland.

3. Passwang road pass · 943 m

   Passwang is a Jura crossing at 943 metres between Balsthal in the Solothurn canton and the Baselland valleys to the north. It is a proper mountain road in miniature, and for many riders it is the highlight of this part of Switzerland, because it packs good bends, long views and quiet forest into a short distance. The road leaves Balsthal through the Gäu and the gorge of the Klus, then climbs through Mümliswil in a series of rising bends toward the saddle.

   The northern side drops toward Reigoldswil and the Waldenburg valley, where a narrow-gauge railway, one of the oldest of its kind in the country, runs beside the road and sometimes crosses it. The grade is moderate, the bends are well engineered, and the surface is generally smooth, though the occasional patch of frost heave appears after a hard winter. In summer, cattle graze the high pastures near the top, and on clear days the view reaches over the folded Jura toward the Black Forest, with the Alps visible further off as a pale line on the southern horizon.

   Passwang is usually open all year, but snow and ice can close it briefly in winter, and early mornings in spring can be treacherous in the shade. Fuel is better planned for Balsthal, a town of nearly six thousand at the foot of the south side, or for the larger centres on the plain.

   Geologically, the Jura is the product of the same pressure that raised the Alps, but felt at a distance. The rocks here were pushed into folds like a rug crumpled against a wall, and the ridges you cross follow the pleats. Limestone gives the region its caves, springs and bright, dry-stone character, and also its wildflowers: orchids and gentians on the high meadows in early summer. A slow pass and a quiet morning will get you the most out of it.

4. Solothurn food stop food · 430 m

   Solothurn has a habit of making visitors ask why they have not come sooner. It sits on the Aare at the foot of the Jura, about fifteen thousand people living in what is probably the best-preserved Baroque town in Switzerland, and for a couple of centuries it was the seat of the French ambassador to the Confederation. That gave the place a refinement out of proportion to its size: grand townhouses, fountains in every square, and a cathedral built in the eighteenth century in pale Ticinese style, dedicated to Saint Ursus.

   The town has a thing about the number eleven. There are eleven churches and chapels, eleven fountains, eleven museums, and the cathedral's steps are laid out in groups of eleven. Locals will tell you the story with a straight face, and whether or not it is quite exact, it adds to the charm. The old town is compact and walkable, with arcades and painted shutters, and the river path, lined with plane trees, is a lovely place to eat a sandwich while the Aare slides past.

   For a food stop it is ideal. There are bakeries, cafes with outdoor tables on the square, and a Saturday market that fills the streets with cheese, bread and vegetables. Fuel is plentiful on the ring roads around the centre, and parking for bikes is easier than in bigger cities, though in the old town itself you will want to leave the machine on the edge and walk.

   The riding around Solothurn is a pleasant mix. To the north the Weissenstein ridge climbs into the Jura, with a road that gains height quickly and offers views over the Mittelland and, on a clear day, a long line of Alpine summits from the Eiger to Mont Blanc. To the south the landscape is gentler, farmland with the Aare carving lazy loops. Traffic in the centre can be slow, and the morning commute clogs the bridges, so aim for mid-morning or the quiet afternoon. The film festival in January and the farmers' markets give the town a lively rhythm all year, but late spring, when the lime trees bloom, is when it looks its best.

5. Hallwilersee water stop stop · 449 m

   Hallwilersee is one of the quieter lakes of the Swiss Plateau, a long, narrow stretch of water in the Aargau hills some forty kilometres south-west of Zürich, lying in the Seetal valley at roughly four hundred and fifty metres. It lacks the drama of the lakes near the Alps, but it has a gentle beauty that appeals to those who prefer a slower pace: green meadows, orchards, small harbours and a swimming beach on each shore. In summer, rowing boats and paddle boards dot the surface.

   At the northern end stands Schloss Hallwyl, a moated castle that is one of the best-preserved water castles in Switzerland. The Hallwyl family held it for centuries, and the buildings, which date from the twelfth century onward, are set on two islands in a pond and surrounded by gardens. Inside, a museum shows how the nobility lived. The area is also home to some of the oldest lake dwellings in the region, with prehistoric pile settlements around the shore that form part of a UNESCO listing of the Alps' pile-dwellings.

   For a rider, the ride around the lake is a pleasant interlude between more ambitious roads. Minor lanes follow the shore through villages such as Meisterschwanden, Beinwil and Seengen, with good surfaces and gentle bends, and the climb to the ridge above the lake gives wide views. The Seetal is a favourite with cyclists, so take care on weekends, and speed cameras are common. It makes a good water stop on the way to the Jura, with plenty of cafés and lakeside restaurants where you can sit with a drink.

   Meisterschwanden has about two and a half thousand people, with a few shops and places to eat, and Reinach, a few kilometres away, has fuel and larger supermarkets. Regional roads here are well signed, and motorcyclists will find parking easy at the lakeside.

   Try fresh lake fish, such as perch fillets, if you see them on the menu, and a glass of local white wine from the Seetal hills. The evening light on the water makes it hard to leave.
