Hut reality check
Sleeping-bag liner — blankets or duvets provided
CAI rifugi: guests must use a sleeping-bag liner (sacco-lenzuolo); blankets are provided and must be folded. Ask the manager if you have none. Private rifugi on AV1 can differ — not invented as a whole-route statute.
Half-board is the usual rifugio offering. No central walking permit on this record.
No central AV1 portal — contact rifugi one by one. How hut-to-hut booking works.

High 2,588 m minus low 389 m is 2,199 m of relief on this record. A standard tropospheric lapse of 6.5 °C per 1,000 m implies about 14.3 °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.

Ingested from OpenStreetMap relation 177743 (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 2D length is 118 km (relation 177743; Alta via n. 1 delle Dolomiti, ref AV1, from Lago di Braies to Belluno, Wikidata Q1236280). OSM tagged distance=125. Alternative, approach, and excursion members were dropped so the snap stays on the main Braies–Belluno line, not AV2–AV6 or the Valle d'Aosta AV1. lengthKm is verified: 118 km is within ~3% of Cicerone/CAI ~120 km (independent published figure; geometry clean after alts dropped; https://www.cicerone.co.uk/alta-via-1-trekking-in-the-dolomites, checked 2026-08-24). Published 8–13 days remain a window, not a DataPoint. Wikipedia 125 km / Wikivoyage ~120 km (https://en.wikipedia.org/wiki/Alta_Via_1, checked 2026-08-24, CC BY-SA; https://en.wikivoyage.org/wiki/Alta_Via_1, checked 2026-08-24) stay in the published band.
DEM high 2,588 m is in the Dolomite-pass band (~2,000–2,750 m), 164 m under Wikipedia's Rifugio Lagazuoi 2,752 m (same Wikipedia page, checked 2026-08-24) — classic DEM/vertex undershoot. High point left as Copernicus, not overwritten with the hut elevation. Cumulative DEM ascent 7,713 m vs Wikipedia ~7,300 m is a cross-check only.
typicalDays 12 is the published typical hut-to-hut itinerary (Cicerone Alta Via 1, ~2 weeks / 11 stages, https://www.cicerone.co.uk/alta-via-1-trekking-in-the-dolomites, checked 2026-08-24). Published window 8–13 days; not a DataPoint. Season: mid-June–late September when huts are open and paths are mostly snow-clear (same page).
Water was not mapped to named WaterSource points (no honest atFraction). Rifugi and springs exist along the route; Wikivoyage notes limestone drainage and dry troughs on some southern stages — not positioned here.

Permits & fees
Permit status is unverified. Permit fields were not sourced from OSM. Confirm locally before travel. No central booking or walking-permit authority was found for Alta Via 1 (Wikipedia Alta Via 1, https://en.wikipedia.org/wiki/Alta_Via_1, checked 2026-08-24; Wikivoyage Alta Via 1, https://en.wikivoyage.org/wiki/Alta_Via_1, checked 2026-08-24). Rifugi (CAI and private) are booked individually — logistics, not a walking permit. No walking fee was stated. Left unverified rather than asserted.
Getting there
Sourced legs to the Lago di Braies / Pragser Wildsee (OSM line start) base start station — where this trail record begins. This is not a route planner: durations are approximate and marked provisional until an official transport page confirms them.

Hazards
- Alpine weather: temperatures can drop sharply in midsummer; snow on high passes (especially Forcella del Lago) is not unusual into July after a hard winter (https://en.wikivoyage.org/wiki/Alta_Via_1, checked 2026-08-24, CC BY-SA).
- Steep, rocky, and occasionally exposed limestone ground; full days with large climbs and descents (same Wikivoyage page, checked 2026-08-24).
- The standard AV1 itinerary does not require via ferrata gear. The optional Via Ferrata Marmol finish to Rifugio 7° Alpini does; hikers without that kit can take the walking descent to La Stanga/La Pissa. Some optional extensions and the Lagazuoi Tunnels descent have iron cables on exposed ground (same page, checked 2026-08-24).
- Altitude exposure around 2,000–2,750 m on the high stages (Wikipedia high point Rifugio Lagazuoi 2,752 m, https://en.wikipedia.org/wiki/Alta_Via_1, checked 2026-08-24).
