About ER1
ER1 is a 20.0 km hiking route in Luxembourg. It climbs roughly 830 m (2,723 ft) along the way. Most people take around 5 hr 34 min at a comfortable pace, plus stops. This is a demanding day. The climbing is sustained and the descent is long enough to punish tired knees.
The character of the walk comes from the landscape it crosses rather than a single headline sight, which is exactly why it stays quiet even in high season.
It runs point to point, so arrange transport at the far end or plan a return leg before you set off. 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. The route is maintained by visit-eislek.
In short, ER1 suits fit hikers with a habit of long days and an eye on the forecast. Dog access is not formally recorded here, so check locally before bringing one.
Plan around this route’s details
- Start, finish and return
- The recorded 20.0 km line has different endpoints. Confirm travel from the finish before setting out; that return journey is additional to the mapped route.
- Climbing in context
- The recorded ascent averages approximately 29 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 634 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.

Climbing and descending by section
Use these equal-distance sections to see how climbing and descending are distributed along the stored elevation profile. Distances follow the profile’s recorded direction; walking in reverse swaps ascent and descent and reverses the section order.
| Section | Profile distance | Ascent | Descent |
|---|---|---|---|
| First third | 0.00–6.56 km | 202 m | 91 m |
| Middle third | 6.56–13.13 km | 186 m | 303 m |
| Final third | 13.13–19.69 km | 231 m | 273 m |
How these numbers are calculated
We split the stored profile into three equal distances and interpolate elevation at each boundary. Rising samples count towards ascent; falling samples towards descent. Totals can differ from the headline figures, which may use different smoothing or rounding. Sparse samples, gaps in the source route and elevation-model errors limit accuracy. These are calculations, not surveyed sections, directions or terrain assessments.

Your walking-time scenario
Adjust the example pace and allowances to explore your own plan. This calculator uses your inputs, so it may differ from the directory’s headline estimate.
Calculated walking time including your allowances
6 hr 29 min
301 min for distance + 58 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 route is normally walked in the direction described below. The first third does most of the climbing, so settle into a slow rhythm early rather than trying to hold a flat-ground pace. Because the finish is away from the start, check return transport before committing to the second half.

Tips from the trail
- Start at first light. A long day is far more pleasant when you are not racing the sunset on the descent.
- 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
- This route is long and sustained. Turn back early rather than late if the weather closes in.
- Outside the main season expect snow, ice or closed access on the higher sections.
Safety
Emergency services in Luxembourg 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
- Trekking poles for the descent
- Offline map and compass
- Head torch and spare battery
- Extra warm layer
- Sun hat, sunglasses and high-factor sun cream
- Real food, not just snacks
Photography
Overcast light suits this route better than harsh midday sun, especially under tree cover. Take the shot on the way out. Conditions rarely improve by the time you come back past. A wide lens captures the scale, but a short telephoto is what turns a good view into a photograph.
