Alta Via 1 vs Alta Via 2 — which Dolomites traverse to pick

Alta Via 1 is the classic — graded walking through the most photogenic scenery in the Dolomites, no via ferrata required, very busy in season. Alta Via 2 is a serious mountaineer's route — higher, harder, with mandatory cabled sections, far emptier, and rewarding in proportion.

If this is your first Alps hut-to-hut: AV1. If you've done a few and want exposure and solitude: AV2.

AV1 is 120 km over 10–11 walking days, Braies to Belluno. AV2 is 160 km over 13–14 days, Brixen to Feltre. Both can be cut into 7-day sections that capture the best half.

Most walkers do not finish the full route in either case — AV1's Schiara finish and AV2's Pale di San Martino end are both significantly harder than the middle sections, and many parties bail to a valley on day 7 or 8. That's a normal choice, not a failure.

AV1 is a graded walking route. The 'ferrata' on it is one short cabled descent off Nuvolau, easily done without a kit. The Schiara variant at the end has real B-grade ferratas — most walkers skip it.

AV2 has multiple mandatory B-grade and one C-grade ferrata sections, including the well-known Brigata Tridentina under Pisciadù. You need the kit, you need to be comfortable with exposure, and you need to know how to clip past anchors quickly. A bad-weather day on AV2 can pin you in a hut — the alternative routes around the ferratas are long.

AV1 walks under the famous walls: Croda da Lago, Pelmo, Civetta. You spend a lot of time on grass terraces and forest paths looking up. The light on the limestone is the visual signature.

AV2 walks across the plateaus and over the passes: the Sella massif, the Marmolada north face, the Pale di San Martino moonscape. You spend more time above tree line and on rock. The geology is the visual signature.

AV1 in July and August is busy — Lagazuoi, Nuvolau, Coldai and Tissi book out within 14 days of the calendars opening in March. AV2 in the same season is comparatively quiet; you'll see other walkers each day, but the famous-photo bottleneck is missing.

If you can't book AV1 huts by mid-April for a July or August trip, switching to AV2 (or AV4, AV5, AV6) is a much better fallback than walking AV1 in September without bookings.

AV1 finishes at Belluno — a real train station with direct service to Venice, easy to get out. The start at Lago di Braies is the hardest part of either route to reach by public transport.

AV2 starts at Brixen/Bressanone — one train from Innsbruck or a 90 min train from Verona. The Feltre finish has rail back to Padua and Venice. AV2 is the logistically easier route if you're flying via Innsbruck or Munich.

Pick AV1 if any of these are true: this is your first hut-to-hut trek, you don't have via ferrata experience, you want guaranteed-cinematic scenery, you can book by March.

Pick AV2 if any of these are true: you've walked the GR20, TMB or another long Alps route already, you're comfortable on B-graded cabled terrain, you want fewer people, your booking window is May or later.
