Dinosaure grandeur nature du zoo préhistorique de l'Aven Marzal, à Saint-Remèze en Ardèche

The Aven Marzal: a cave and dinosaur zoo for families

Life-size dinosaurs along a woodland trail, a spectacular cave to explore, a museum for the curious: the Aven Marzal, in Saint-Remeze, is one of children’s favourite outings in Ardeche. Just 15 minutes from Mas Saint Antoine, this site brings together three discoveries in one place — including France’s very first prehistoric zoo. After ten years advising our guests, here is our complete guide to a great family visit.

What is the Aven Marzal?

Located in Saint-Remeze, at the gateway to the Ardeche Gorges, the Aven Marzal brings together three complementary attractions: a cave to visit, an underground-world museum, and a prehistoric zoo full of dinosaurs. This is what makes it an ideal family outing: there is something for everyone, from toddlers fascinated by the dinos to older children keen on geology.

The prehistoric zoo: a children’s paradise

This is THE big attraction for children. Created in 1983, it is France’s first prehistoric zoo: a shaded trail of about 800 metres, lined with around twenty life-size reproductions of dinosaurs and prehistoric animals, from primitive fish to Cro-Magnon man. The walk is outdoors, at a gentle pace, at a child’s eye level. A dream for little dino fans — camera recommended!

The Marzal cave: an underground adventure

The cave is visited with a guide, discovering halls adorned with crystalline formations in astonishing shapes. It is magnificent — but let us be honest: the visit involves many steps, with a substantial descent and climb back up. It will delight children old enough to walk, but is not well suited to toddlers in a pushchair. Bring a light layer: underground, it is cool all year round.

The Underground World Museum

Often free to enter, this small museum retraces the history of caving and pays tribute to the great explorers who unlocked the mysteries of the underground. A short, instructive stop that nicely complements the cave and the zoo.

How to reach the Aven Marzal from Mas Saint Antoine?

The Aven Marzal is in Saint-Remeze, on the Ardeche Gorges road, about 15 minutes’ drive from Mas Saint Antoine. It is an ideal outing for a half-day, or even a full day if you take in all three sites.

Frequently asked questions

Where is the Aven Marzal located?

The Aven Marzal is in Saint-Remeze, on the Ardeche Gorges road, in southern Ardeche. It is about 15 minutes’ drive from Mas Saint Antoine and just a few minutes from the Grotte de la Madeleine, which makes it easy to combine the two sites.

Is the Aven Marzal suitable for children?

Yes, it is a very popular family outing, mainly thanks to its prehistoric zoo and life-size dinosaurs, on an easy outdoor trail. The cave, however, has many steps: it will delight children old enough to walk, but is not well suited to toddlers in a pushchair.

What is there to see at the Aven Marzal?

Three sites in one: a spectacular cave visited with a guide, an underground-world museum retracing the history of caving, and above all France’s first prehistoric zoo, an 800-metre trail lined with around twenty life-size dinosaurs and prehistoric animals. Enough to keep young and old busy.

What is the Aven Marzal prehistoric zoo?

It is France’s first prehistoric zoo, created in 1983. Along a shaded trail of about 800 metres, you discover around twenty life-size reproductions of dinosaurs and prehistoric animals, from primitive fish to Cro-Magnon man. The walk is outdoors and gentle: a real delight for children who love dinosaurs.

Is the cave visit difficult?

The cave is visited with a guide and has many steps, with a substantial descent and climb back up. It suits children old enough to walk and people comfortable with stairs, but is not recommended for toddlers in a pushchair or people with reduced mobility. Bring good shoes.

Do you need to book to visit the Aven Marzal?

The cave is generally a guided visit at set times, while the zoo and museum are explored more freely. Depending on the season and how busy it is, it can be worth checking the guided-visit times in advance. The safest is to consult the Aven Marzal’s official website before your visit.

What is the best time to visit the Aven Marzal?

The site is open for much of the spring to autumn, and closed in winter. The cave, cool and constant, is ideal on very hot days; the zoo, outdoors, is best in fine weather. Autumn, quieter, is perfect to avoid the crowds. Check the opening dates on the official website.

How long should you allow for the visit?

Allow about an hour for the guided cave, as long again to wander the prehistoric zoo, plus a moment at the museum: in total, a good half-day, or even a full day if you take your time and picnic on site. It is an outing that pleasantly occupies a whole family.

How should you dress to visit the Aven Marzal?

For the cave, bring good shoes (many steps, sometimes damp ground) and a light layer, as it is cool all year. For the outdoor prehistoric zoo, clothing suited to the weather and a hat in summer are enough. The contrast between the cool cave and the open air is also part of the charm of the visit.

What else can you do around the Aven Marzal?

The Saint-Remeze area is ideal to extend the day: the nearby Grotte de la Madeleine, the panoramic Ardeche Gorges road and its viewpoints, or the Pont d’Arc and river swimming. You can easily combine the Aven Marzal with one of these discoveries, all a few minutes away.
