Altitude weather delta
High 2,109 m minus low 222 m is 1,887 m of relief on this record. A standard tropospheric lapse of 6.5 °C per 1,000 m implies about 12.3 °C cooler at the high point than the valley, all else equal.
That is a model (International Standard Atmosphere environmental lapse), not a forecast and not a trail-closure. Wind, snow, and storms stay in Hazards.

Moderate (Easy technical / Medium physical)

- Mountain hiking. Continuous trail, some steep ground, sure-footedness helpful.
- YDS Class 1
- Class 1. Walking on an established path; low fall risk.
Ingested from OpenStreetMap relation 1107386 (ODbL). The mapped line and 2D length are derived from that geometry. Ascent, descent, and high/low points are sampled from Copernicus GLO-30 (copernicus-dem:glo-30) and remain provisional. Water, permits, and hazards were not taken from OSM tags and must be verified.
OSM walking 2D length is 510.1 km (relation 1107386; type=superroute, ref=2, network=nwn, operator=Wanderland Schweiz). Numbered stages 1–32 stitched. lengthKm is verified walking: 510.1 km is within 3% of the official 510 km (https://www.schweizmobil.ch/en/hiking-in-switzerland/route-2; https://www.myswitzerland.com/en/experiences/route/trans-swiss-trail/, 510 km / 32 stages / 17,700 m ascent, checked 2026-09-09). Official km is the ±3% cross-check, not this DataPoint.
Official transport leg (not walking, not in lengthKm): stage 7 Neuchâtel → Murten begins with a scheduled boat across Lac de Neuchâtel to Cudrefin because there are no suitable trails (https://www.schweizmobil.ch/en/hiking-in-switzerland/route-2/stage-7; SchweizMobil text on https://www.j3l.ch/en/V1910/things-to-do/sport-leisure/hiking/trans-swiss-trail, 19 km walking after the boat, checked 2026-09-09). OSM gap 7.1 km from 46.9910°N 6.9332°E (Neuchâtel) to 46.9593°N 7.0138°E (Cudrefin). That chord is not densified and is not walking distance.
DEM high 2,109 m is an alpine-pass sample on the Gotthard section of this north–south line. GLO-30 cumulative ascent 11,194 m is the same order as the official 17,700 m figure (same MySwitzerland table, checked 2026-09-09). High point left as Copernicus.
Water was not mapped to named WaterSource points (no honest atFraction). Villages and inns exist; they were not positioned from an official named list this pass.
