About Sentier du Trou de Fer
Sentier du Trou de Fer is a 8.1 km hiking route in Parc national de La Réunion (cœur). It climbs roughly 178 m (584 ft) along the way. Most people take around 1 hr 57 min at a comfortable pace, plus stops. The effort is honest but manageable, and the hardest section is over quickly.
There is no one famous view here. The appeal is the sustained quality of the walking and the fact that you are unlikely to share it with a crowd.
The circuit closes on itself, which makes logistics simple: one car park, one round of 5.0 mi. It is not consistently waymarked, so carry a map or a downloaded track rather than relying on signs.
Spring through autumn is the natural window, and shoulder season means fewer people on the narrow sections.
In short, Sentier du Trou de Fer suits regular walkers who want a full day without technical ground. Dog access is not formally recorded here, so check locally before bringing one.

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.
- Download the track to your phone before you leave. Signal is not guaranteed.
- Leave nothing behind, including fruit peel, and stay on the marked line to protect the ground either side.
Warnings
- 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
Overcast light suits this route better than harsh midday sun, especially under tree cover. 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.
