Agri-tourism in Provence?

https://www.bienvenue-a-la-ferme.com/ is where you start

We enjoyed a visit here this past summer for olive oil grove and factory tour.

Nearby are the Roman ruins of Glanum, the Van Gogh asylum and walk into St Remy and the castle at Les Baux. If you get to Les Baux don't miss the pretty church and Yves Grenet museum in the town. I had those all to myself one day in August even when the castle was heaving with visitors.

Also, I had copied the below route from some version of a local tourism brochure near where we were staying in Maussane les Alpilles but didn't get a chance to check them out (except Castelas):

"1/ SAINT-ETIENNE-DU-GRÈS: LES OLIVADES, AUTHENTIC FABRIC MANUFACTURE IN PROVENCE This circuit begins with Saint-Etienne-du-Grès where the last factory is located in Provence to perpetuate the tradition of printing on fabric born in Marseille in 1648. You will have access to the factory store and can bring back high-end items Made in France which are available in ready-to-wear, accessories, luggage or tableware.

2/ FONTVIEILLE: HEADING FOR THE DOMAIN OF THE CHÂTEAU D’ESTOUBLON (WINE AND OLIVE OIL) Then descend towards Fontvieille, known for housing the Moulin de Daudet made famous in the Lettres de Mon Moulin. You can visit the grounds of Château d'Estoublon, a wine and olive-growing estate. This site installed in a beautiful and imposing 18th century Provençal residence is worth the detour! A small delicatessen offers wines and oils produced on site as well as local sweets for the pleasure of gourmets.

3/ LES BAUX: THE MOULIN CASTELAS FOR OIL AND FOR WELCOME You can resume the walk with the Moulin Castelas, at the foot of the Château des Baux. A couple of enthusiasts, the Hugues, lovingly cultivate an olive grove that extends over 45 hectares to produce AOP Vallée des Baux-de-Provence olive oils. The mill and the factory can be visited, allowing the tasting of oils and a passage to a charming shop with a thousand sunny scents.

4/ MOURIÈS: MAS DE LA TAPI, AN ORGANIC OLIVE OIL PRODUCER Then join Mouriès and its 90,000 olive trees (and more), to discover the Mas de la Tapi committed to organic farming. Five generations have passed on a unique know-how to produce a PDO Vallée des Baux-de-Provence extra virgin olive oil.

5/ AUREILLE: VILLAGE WITH A TENDER HEART IN A ROCKY SETTING We continue the road that runs along the Regional Natural Park of the Alpilles towards the charming village of Aureille which we will not fail to visit. It is an old fortified village full of charm, whose alleys are drawn over the stone houses recently restored. At the top of the village, Castelas dominates, a remnant of the Middle Ages. Do not miss its small parish church either.

6/ EYGUIÈRES: A TASTING AT THE CHIARI CHEESE FACTORY, WHAT YOU SAY? A little further in Eyguières, stop off at the Chiari cheese dairy. His herd of white Saanen goats lives in the open air and benefits from an exceptional terroir, the secret of good milk. It is then transformed into fresh or mature cheeses, with or without olive oil, thyme and garlic.

7/ ORGON: DOMAINE DE VALDITION, ANOTHER VERSION OF HIGH-END TRADITION Then go up to Orgon, on the way admire the Notre-Dame-de-Beauregard chapel which watches over the valley. Do not miss the Domaine de Valdition for a tasting of high quality olive oil and wine in an exceptional setting (a bastide surrounded by bicentenary trees).

9/ SAINT-RÉMY: END OF A GOURMET DAY IN THE HEART OF THE ALPILLES To end this busy day, return to Saint-Rémy where you can eat. And don't forget to push the door of the confectioner Lilamand (avenue Albert Schweitzer), and let yourself be tempted by a candied fruit to taste on the spot or to bring back in your suitcases if you can resist it! Confectioner Pierre Lilamand still uses the Nostradamus recipe to make his fruity delights (calissons, jams, etc.)."

I can't speak to the quality of this organization, but here you go: https://www.chateauvirant.com/en/info/make-your-own-olive-oil.html

Some great tips here, and the farm website is a great place to start, thank you! We’re hoping for something other than olive oil or wine, if anyone has had good experiences in other areas?

Although the website is not in English (use an online translator.), I recommend that you visit the "Bienvenue à la ferme" (Welcome to the Farm) mentioned by Simon.
This is 100% what you are looking for.
