People often ask me, at the cellar door, whether there is "anything to do" around Berlou before or after a tasting. The answer comes down to a single trail: the Oenorando du Mas Blanc. Six kilometres, an hour and a half, and the essentials of what there is to understand about the terroir are right there under your boots.

What is an Oenorando®?
Oenorando® is a collective trademark registered by the Département de l'Hérault, run by the Comité départemental de la randonnée pédestre, with routes certified by the FFRandonnée. The principle is simple: a loop that leaves from and returns to the same point — a cellar or a maison des vins — and crosses the vineyards of the appellation.
The Hérault has 29 of them. The Mas Blanc is the only one in the commune of Berlou.
The route
You set off from the place du Pont, in the heart of the village. The path climbs towards the first vines, runs alongside them, then drops onto a track that runs between the plots for about 500 metres. This is the most telling stretch of the circuit: you walk level with the vine stocks, on the schist, and you suddenly understand why the vine struggles here — the soil is a stack of dark plates, poor, free-draining, with no real earth to speak of.
The high point is the col de Merly, with a 360° view: the Caroux massif to the north, the pic de Naudech, and to the south the whole amphitheatre of vines dropping away towards the valley. The official route sheet advises caution when crossing the road at this spot. Further on, the Serre des Cayrils offers the best viewpoint over the village itself.
The way back crosses a pontil over a stream, climbs through a pine wood and then the garrigue, skirts a vineyard and a mazet, and comes back down past the cooperative cellar and then the cemetery.
Two steep climbs are signposted: after point 2, then between points 5 and 6 — this last section also including a steep descent.
One rule to respect
The official route sheet states it explicitly, and I am glad to repeat it: respect the winegrowers' work, do not pick the grapes. These plots are someone's income, and a bunch taken in August from a cru limited to 40 hectolitres per hectare is not a detail. Staying on the waymarked paths also avoids compacting the soil at the foot of the vine stocks.
Three things the route sheet does not say loudly enough
- La Maison du Cambrien, a palaeontology museum, is 200 metres from the route — just carry on along the road. The area is a recognised geological study site, which is no accident: it is the same ancient bedrock that gives the vineyards their schist.
- Four geocaches are hidden along the route. Enough to keep children going over 6 km, which is no small thing.
- No public transport serves Berlou: come by car. Free parking at the place du Pont and at the church. From Béziers, allow around thirty kilometres and about 40 minutes.
When to go — and when to stay away
This is the most important point in this article, and the one hiking sheets cover least.
Berlou falls within forest sector no. 06 "Minervois et Saint-Chinianais" under the prefectoral order regulating access to the massifs. Hérault Tourisme describes this sector as highly exposed to fire in summer and regularly placed on orange or red alert.
The order applies from 15 June to 30 September, and may be extended by prefectoral order in exceptional circumstances. There are four danger levels — green, yellow, orange, red:
- green and yellow → access permitted without restriction;
- orange → access not advised;
- red → access forbidden.
The level that applies to the following day can be consulted from 17:00. So you have to check it the evening before, not on the morning itself as you arrive at the car park. Two official sources to bookmark:
- Hérault fire risk map (with a "localisez-moi" button on mobile)
- Météo des Forêts — Météo-France
If you see suspicious smoke: 18 or 112. And a reminder that holds all year round: all fires are forbidden in forest areas and within a 200-metre perimeter around them, whatever the risk level.
What to take
Water, and more than you think. A drinking water point is signposted next to the church in Berlou, at the secondary car park — fill up there, because nothing more is signposted along the route. The circuit crosses areas of garrigue with little shade. Hat, sun cream, closed shoes: the plates of schist are slippery on the way down, especially after rain.
After the walk
You will have spent an hour and a half walking on the soil that makes these wines. The logical next step is to taste the result.
The Domaine de Cambis is in the village, at 2 route de la Mausse. We farm 10 hectares under certified organic agriculture, on this same schist, between 200 and 400 metres of altitude. Tastings are by prior booking, with the winegrower, on the panoramic terrace — facing the hillsides you have just walked across. In French, English or Spanish.
- Formule Découverte — €15 per person, about 1 hr, four wines with commentary
- Formule Gourmande — €50 per person (from 2 people), about 2 hrs, the full range and a board of tapas from local producers
In both cases, €15 per person is deducted on any wine purchase of €150 or more. Book a visit →
A word of common sense: if you are driving afterwards, the legal limit in France is 0.5 g/l — roughly two glasses, and only 0.2 g/l for drivers on a probationary licence. A spittoon is available, and nobody here will take offence. It is in fact the norm.
Frequently asked questions
Is the Oenorando du Mas Blanc suitable for children?
The circuit is graded easy, over 6 km with 283 metres of elevation gain, but it includes two steep climbs and a descent to watch out for between points 5 and 6. It suits children who are used to walking. The four geocaches along the route are a good motivator.
Can this hike be done in summer?
Yes, but you must check the Hérault fire risk map the evening before: Berlou is in sector 06, and the prefectoral order applies from 15 June to 30 September. At orange, access is not advised; at red, it is forbidden. The following day's level is published from 17:00. Set off early, with plenty of water.
Is there water along the route?
A drinking water point is signposted next to the church in Berlou, at the secondary car park at the start. Nothing more is signposted along the route itself. Public toilets are available at the main car park.
Can you eat the grapes in the vineyards?
No. The official route sheet explicitly asks visitors to respect the winegrowers' work and not to pick the grapes. The plots you cross are working vineyards.
Which map should I use?
The IGN 2543 OT map covers Berlou. The GPX track can be downloaded free of charge from the Hérault Tourisme website.
