About Sentier des bulbocodes

Sentier des bulbocodes is a mapped hiking route in Valais/Wallis, Switzerland. The mapped distance is 3.6 km (2.2 mi), with 238 m (781 ft) of recorded ascent, with 238 m (781 ft) of recorded descent. Its recorded high point is 654 m (2,146 ft) and its low point is 466 m (1,529 ft). The displayed moving time of 1 hr 6 min is a planning estimate based on distance and ascent, before breaks.

Hiking Trail Directory rates this route moderate from the available distance and elevation measurements. That rating is useful for comparing routes in the directory, but it does not establish technical terrain, exposure, path condition or the skills required on the day. The mapped line is a loop and returns to its starting area.

The source data records route tags for waymarked route, membership of the lwn network and a waymark record with the symbol “green:yellow:green_rectangle:Sdb:white”. These attributes describe the route record as a whole; they do not prove that every section has the same surface, signage or feature.

The directory season field highlights april to october. This is planning metadata, not a live statement about snow, closures or trail condition.

The map is derived from OpenStreetMap and contains 35 geometry points. Elevation values were sampled from terrarium-z11. The traceable source record is 15467562. Open-data records can lag behind reroutes and closures, so compare the source, official notices and the forecast before travelling.

Plan around this route’s details

Start, finish and return
This route is recorded as a 3.6 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 66 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 238 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.

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.

Make it fit your day

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

1 hr 48 min

54 min for distance + 24 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 mapped line is a loop and returns to its starting area. The mapped distance is 3.6 km (2.2 mi), with 238 m (781 ft) of recorded ascent, with 238 m (781 ft) of recorded descent. The sampled elevation profile records a maximum grade of about 60%; this is a calculated value and may smooth short, steeper sections. The profile reaches 654 m (2,146 ft) from a recorded low of 466 m (1,529 ft).

Tips from the trail

  • Open the linked source record before departure to check whether the mapped relation has changed.
  • Save the route line offline; a map download is useful regardless of expected phone coverage.
  • Use 1 hr 6 min as estimated moving time, then add your own allowance for stops, conditions and daylight.
  • Confirm the exact trailhead and permitted parking or public-transport options locally.
  • Carry enough food and water for the full route; water availability is not established by the map data.
  • Follow local access rules and leave no litter or food waste behind.

Warnings

  • This guide does not contain live information about closures, hazards, snow, flooding or path condition.
  • The sampled profile includes a grade of about 60%; verify the terrain and your footing requirements locally.

Safety

Emergency services in Switzerland can be reached on 112. Share your route and expected return time with someone before leaving. The directory has no verified coverage map or live trail-status feed, so do not rely on phone reception or this page alone. Turn around when conditions, access or your remaining time no longer match the plan.

What to bring

  • Footwear suited to the current surface and conditions
  • Weather layers appropriate to the local forecast
  • Offline route map and a backup navigation method
  • Food and water for the planned time plus a reserve
  • Charged phone and a small first-aid kit

Photography

Photo locations are not mapped in the source data for Sentier des bulbocodes. Stay on permitted ground, keep clear of edges and moving water, and never block the route while setting up. Check local rules before using a tripod or drone, especially inside protected areas.
