About Source Combe de la Lune

A Brief Description

Source Combe de la Lune is a natural spring that feeds the Vistre river (its exutoire). The water emerges from calcaires et calcaires marneux de l’Hauterivien inférieur—lower Hauterivian limestone and marl—a testament to the ancient marine sediments that once covered this part of southern France. When heavy rain falls, the spring swells into a gros débit (strong flow), creating a dramatic, frothy cascade that can be heard echoing through the surrounding woods.

History & Significance

Unlike many of the region’s more commercialized attractions, Source Combe de la Lune has remained non‑aménagée, preserving its natural state for centuries. Historically, local farmers and shepherds relied on the spring’s reliable water source for livestock and irrigation. The name “Combe de la Lune” (literally “valley of the moon”) likely stems from the way moonlight dances on the water’s surface during clear nights, a poetic image that has inspired local folklore.

From a geological perspective, the spring offers a living laboratory. The Hauterivian limestone is part of the larger Cretaceous sequence that defines much of the Languedoc‑Roussillon landscape, providing clues about ancient sea levels, sedimentation patterns, and the tectonic forces that shaped the region. For students, researchers, or curious travelers, a quick stop at the spring can turn a simple hike into an impromptu field trip.


How to Get There

By Car

The most flexible way to reach Source Combe de la Lune is by car. From Nîmes, follow the D6102 heading north‑west toward the small hamlet of Mas de Roulan. After about 12 km, turn left onto a local dirt road marked by a modest sign reading “Combe de la Lune”. The road is narrow but well‑maintained; a standard passenger vehicle can navigate it without trouble. Parking is available in a small gravel lot just off the road—no fees, but arrive early during peak weekend months to secure a spot.

By Public Transport

Public transport options are limited, as the spring is located in a rural zone. The nearest SNCF train station is Nîmes, where you can catch a regional TER service toward Uzes. From the Uzes stop, a local bus (line 42) runs sporadically on weekdays; however, the schedule does not align well with the spring’s opening hours. For most travelers, a rental bike or a taxi from Nîmes to the trailhead is the most reliable alternative.

By Foot / Hiking

If you enjoy long‑distance walking, the spring lies on a moderately graded trail that starts at the Mas de Roulan parking area. The hike is roughly 4 km round‑trip, with a gentle ascent of about 50 m. The path is marked with yellow paint blazes and passes through oak‑crowned slopes, offering scenic views of the surrounding vineyards and limestone outcrops.


Best Time to Visit

Season What to Expect Why It’s Ideal
Spring (Mar‑May) Fresh, clear water; blooming wildflowers; moderate temperatures (12‑20 °C). The spring’s gros débit is strongest after winter rains, giving you a spectacular flow without the summer heat.
Summer (Jun‑Aug) Warm weather; occasional drought may reduce flow. Good for early‑morning visits when temperatures are lower, but be prepared for less water volume.
Autumn (Sep‑Nov) Mild climate; colorful foliage; occasional rain revives the spring’s vigor. A perfect balance of comfortable hiking weather and a revived water flow after September showers.
Winter (Dec‑Feb) Cooler, potentially icy conditions; lower water volume. For adventurous souls who enjoy quiet, mist‑filled landscapes—just bring sturdy boots and check weather forecasts.

Overall, late spring to early autumn (May‑October) offers the most reliable water flow and pleasant hiking conditions.


What to Expect

The Senses

  • Sight: Crystal‑clear water bubbling from limestone fissures, surrounded by low‑lying scrub and occasional patches of lavender. In bright sunlight, the water catches the light like a series of tiny diamonds.
  • Sound: A gentle, continuous murmur that rises to a roar during heavy rain. The sound is amplified by the surrounding rock walls, creating a natural echo chamber.
  • Touch: If you dip your hand in, the water feels cool (often around 12‑14 °C) and mineral‑rich, a pleasant contrast to the warm French air.
  • Smell: A faint, earthy scent of wet stone mixed with the subtle perfume of nearby rosemary and thyme.

Activities

  • Photography: The spring’s reflective surface and surrounding limestone make for striking macro and landscape shots. Early morning or late afternoon light yields the best contrast.
  • Geology Walks: Follow the exposed rock faces to see fossilized shells and trace the layers of the Hauterivian limestone.
  • Picnicking: While there are no formal facilities, a small blanket and a packed lunch can turn the spot into a tranquil lunch spot—just remember to pack out all waste.

Facilities

Source Combe de la Lune is non‑aménagée—there are no restrooms, drinking fountains, or marked trails beyond the basic path. Bring enough water, snacks, and a basic first‑aid kit. The nearest restaurant is in the village of Mas de Roulan, about 2 km away, offering traditional Provençal dishes.


Nearby Attractions

While the spring itself is the star, the surrounding area is dotted with other natural wonders that can easily be added to a day‑trip itinerary:

  • Source puits de Brunel aval – 0.4 km away. A small spring that feeds into a shallow creek, perfect for a quick stop and photo.
  • Source Grevoul – 0.5 km away. Known for its clear water and a short, shaded trail that leads to a rustic stone bridge.
  • Source Amont de la Combe de la Lune – 0.7 km away. The upstream counterpart of our main spring, offering a quieter, more secluded setting.
  • Source de Combe Sourde – 0.7 km away. A low‑flow spring that creates a gentle pool—ideal for a quiet meditation moment.

All of these sites are reachable on foot or by bike, allowing you to craft a “spring circuit” that showcases the diverse hydro‑geological character of the region.


Travel Tips

Tip Details
Footwear Sturdy hiking boots with good ankle support; the trail can be slippery near the water.
Clothing Layered clothing. Mornings can be cool, especially in spring; a lightweight rain jacket is advisable during occasional showers.
Water & Snacks No drinking water on site. Carry at least 1 L of water per person and high‑energy snacks (nuts, fruit bars).
Navigation GPS coordinates (43.864282, 4.380291) work well on most smartphones. Download offline maps of the Nîmes‑Uzes area in case of spotty reception.
Respect the Environment Since the spring is un‑developed, take all litter with you. Avoid stepping on delicate limestone formations.
Safety In heavy rain, the spring’s flow can become swift. Keep a safe distance from the water’s edge, especially if children are present.
Timing Arrive early (before 10 am) during summer weekends to avoid crowds and to capture the best light for photos.
Local Cuisine After your hike, stop at Le Mas de Roulan (10 km south) for a plate of brandade de morue and a glass of Costières de Nîmes wine.
Photography Use a polarizing filter to reduce glare on the water surface and bring a tripod for low‑light shots at dusk.
Seasonal Note If you plan to visit in winter, check local weather alerts. Snowfall on the surrounding hills can make the trail icy.
