Cassini is 9.2 km (5.7 mi) long as a full loop. Most walkers complete it in about 2 hr 24 min, not counting stops.

It is rated moderate, with roughly 323 m (1,060 ft) of total ascent. It sits firmly in moderate territory: enough climbing to feel like a proper day out, never enough to become a slog.

How long does Cassini take?

Allow around 2 hr 24 min of moving time. Add a further 30 to 60 minutes for breaks, photographs and lunch.

When is the best time to hike Cassini?

April to October is the most reliable window. Spring through autumn is the natural window, and shoulder season means fewer people on the narrow sections.

Can you bring dogs on Cassini?

Dog access is not formally recorded for this route. Local rules usually allow dogs on a lead, but check signage at the trailhead before you commit to the walk.

Is Cassini suitable for children?

It is a stretch for younger children. At 9.2 km with 323 m (1,060 ft) of ascent, it suits teenagers and confident young walkers rather than a family stroll.

Yes. The route is circular, so you return to your starting point without repeating any section.

Is Cassini inside Parc national des Cévennes (cœur)?

Yes. The route lies within Parc national des Cévennes (cœur), so park rules on camping, fires and dogs apply along its full length.

About Cassini

Cassini is a 9.2 km hiking route in Parc national des Cévennes (cœur). It climbs roughly 323 m (1,060 ft) along the way. Most people take around 2 hr 24 min at a comfortable pace, plus stops. Expect a steady effort with a few sustained climbs, well within reach if you walk regularly.

The higher sections open out completely, with ridgelines stacking into the distance on clear days. The top is the whole point, and on a clear day the panorama justifies every metre of climbing. Sea air, exposed headlands and constantly changing light make this feel different in every weather.

The circuit closes on itself, which makes logistics simple: one car park, one round of 5.7 mi. The route is waymarked and marked on the ground with its own symbol, so navigation is straightforward in good visibility.

It walks well across three seasons, with spring and autumn offering the best combination of light, temperature and quiet paths. The nearest town of any size is Alès, about 34.5 km away, which is where most people base themselves.

In short, Cassini suits regular walkers who want a full day without technical ground. Dog access is not formally recorded here, so check locally before bringing one.

Plan around this route’s details

Start, finish and return: This route is recorded as a 9.2 km loop. Confirm a permitted access point and include the approach from parking or public transport in your plan.
Climbing in context: The recorded ascent averages approximately 35 m of climbing per kilometre across the whole route. This is climbing density, not trail gradient: climbs and flatter sections may be unevenly distributed. Recorded descent totals 323 m and also needs time in your plan.
What needs a separate check: This record does not establish surface, dog access, wheelchair access. Check any of these that affect your group. Current closures, access arrangements and transport are not verified by the route line.

138 min for distance + 32 min for ascent + 30 min allowance.

Formula: distance ÷ pace × 60 + ascent ÷ 100 × climbing allowance + stops. Travel to and from the route is additional. Terrain, descent, weather and navigation are not modelled. These results do not establish route suitability. Read the time-planning guide.

Recorded route measurements

The loop is usually walked clockwise from the main trailhead. The first third does most of the climbing, so settle into a slow rhythm early rather than trying to hold a flat-ground pace. The upper section is where the route earns its reputation, and it is also where weather changes fastest. The return leg is the reverse of the outward journey, which makes it easy to judge remaining time.

Tips from the trail

Early morning and late afternoon give the best light and the quietest paths.
Aim for april to october for the most reliable conditions.
Check the tide table if any part of the route runs along the beach.
Leave nothing behind, including fruit peel, and stay on the marked line to protect the ground either side.

Warnings

Cliff edges may be unfenced and undercut. Keep well back from the drop, especially in wind.
Outside the main season expect snow, ice or closed access on the higher sections.

Safety

Emergency services in France are reached on 112. Tell someone your route and expected finish time before you set off, particularly if you are walking alone. Mobile coverage is generally usable along this route, but do not rely on it as your only plan. If the weather deteriorates, descending the way you came is almost always the safer option.

What to bring

Comfortable, broken-in hiking shoes or boots
Weatherproof jacket
At least 1.5 litres of water
Sun hat, sunglasses and high-factor sun cream
Small first aid kit including blister plasters

Photography

Shoot the first hour after sunrise from the higher ground: the low angle picks out every ridge and the valleys still hold mist. Because it is a loop, the light changes direction as you go, so save some memory for the back half. A wide lens captures the scale, but a short telephoto is what turns a good view into a photograph.
