About Brocante Montbonnot

The Montbonnot-Saint-Martin flea market, organized by the Comité d'Animation de Montbonnot, takes place every year in September on the site of the Pré Millet business park. This event welcomes individuals and professionals for a day of outdoor treasure hunting, from 8 am to 5 pm. The sale of new items is prohibited: only second-hand items are allowed. Refreshments and food are available on-site, completing this friendly day on the outskirts of Grenoble.

The Montbonnot Flea Market: A Back-to-School Event near Grenoble

Every September, the Pré Millet business park in Montbonnot-Saint-Martin transforms into a vast treasure hunting ground for the annual flea market organized by the Comité d'Animation de Montbonnot. This outdoor event, which traditionally marks the start of the season for treasure hunters in the Grenoble area, attracts both individuals looking to clear out their attics and bargain hunters.

Strict Rules for Quality

The organization stands out with its clear regulatory framework: the sale of new items is strictly prohibited for both individuals and professionals. Individuals can only exhibit a maximum of twice a year, thus guaranteeing the authenticity of the sales. Professionals must be regularly registered. This rigor contributes to the quality of the offerings and the credibility of the event.

Pré Millet, an Ideal Space

The Pré Millet business park offers a large and well-organized space to accommodate exhibitors and visitors. Parking is easily accessible, and the spacious aisles allow for comfortable movement between stalls. Refreshments and food offered on-site by the Comité d'Animation allow attendees to eat throughout the day.

Montbonnot-Saint-Martin, between Chartreuse and Grésivaudan

A residential town in the Grésivaudan valley, Montbonnot-Saint-Martin is located about ten kilometers from Grenoble, at the foot of the Chartreuse massif. The Comité d'Animation, which has been organizing this flea market for several years, also offers other events throughout the year: village festivals, theater performances, and cultural activities. The flea market is one of the highlights of the local community calendar.
