Vendors spread their wares along the harbour wall on a Sunday morning, the Château de Nyon visible above the rooftops and the Alps filling the horizon across the lake. This is the setting for the Puces de Nyon, a monthly flea market that draws more than 200 merchants and antique dealers into the old town streets each month. Stalls stretch along roughly a kilometre of winding lanes, reaching down to the lakeshore and the most coveted pitches of all — the ones with the water right behind them.

The range of goods rewards patient browsing. Vintage jewellery, antique cutlery, old toys, ceramics, textiles and miscellaneous collectibles fill the stalls. Arrive early on the last Sunday of each month, when the market runs from 08:00 to 18:30, and the lakeside pitches still feel fresh and unhurried. The slow pace of the lanes between stalls works in your favour. Cafés dot the route throughout, and stopping for a coffee mid-browse is easy and genuinely worthwhile.

For drivers, arriving at the car park at the top of the hill and walking down through the market is the most practical approach. It follows the natural slope of the old town and lets you cover the route without doubling back. The Puces de Nyon runs every month of the year except August, when Nyon clears the way for its annual event — the Brocante de Rive.

The Brocante de Rive takes place over the last weekend of August, running each day from 09:30 to 18:00. It is a distinctly different proposition. More than 80 professional antique dealers gather for this two-day fair, with the mix leaning heavily toward vintage and mixed secondhand stalls alongside a dedicated antique presence. The event has been running for decades and carries a reputation that draws serious buyers from beyond the region.

Where the monthly market suits a relaxed Sunday browse, the Brocante de Rive rewards planning. Collectors who target specific categories and want direct access to established professional dealers find it more focused than the general market atmosphere. The lakeshore setting remains the same, but the character shifts toward something closer to a curated antiques fair than a flea market weekend.

Nyon itself is compact and easy to navigate on foot, which makes combining a lakeside walk, a café stop and a full morning of browsing feel effortless. If a visit happens to fall in August, the Brocante de Rive offers a strong reason to plan around the date rather than simply arrive.

Getting to the market is straightforward by public transport. The Usine à Gaz bus stop, served by bus lines 803 and 811, sits approximately 100 metres from the market site. Nyon train station, reached by train line R55, is roughly 600 metres away and connects the town to the wider Lake Geneva rail network. For visitors approaching from across the lake, the Nyon ferry stop — served by ferry lines 3150, 3154 and N3 — is also approximately 100 metres away, making an arrival by boat across Lake Geneva a genuinely practical and scenic option.
