The Alta Via 1 is likely to have the
best conditions between mid-July and the end of the August. Huts are generally
open from mid-June until mid-September, which defines the hiking season for the
Alta Via 1. The specific dates for each of our Alta Via 1
itineraries aree defined by the opening season of the huts.
Note
that there is a bike race in the Passo Falzarego area from July 21st to
25th that will cause road closures and will prevent buses from running from the end of this tour. Taxi will have limited operating hours on the
route.
Here's what
conditions to expect at different times of year:
Late June:
Huts are open and routes from the valleys to the huts are clear. Problematic
snow may still remain on the passes and at high elevations, and in some years,
it may be necessary to bypass certain sections of trail using transportation
(which is not convenient and is usually expensive). Even if the passes are
clear in time for your hike, they usually clear at the very last minute, and
June hikers always have a couple of stressful weeks leading up to their hike as
they check webcams and eagerly wait for the snow to melt in time for their
hike. Almost every year, it is not possible to predict what trails are going to
be like in June until one or two weeks before. This is true even after a winter
with low snowfall. If you plan to begin the tour at Malga Ra Stua (this is an easier itinerary than starting at Lago di Braies), you will need to pay for a private taxi transfer up, as the shuttle will not yet be running. The bus to Lago di Braies will be running.
July and
August: Problematic snow can remain on the route through the
first week of July, but it is less likely than in June. If snow remains, trails
should at least be tracked and easy to follow. Beginning the second week of
July, trails are almost always clear. Summer settles in and days are usually
mostly sunny with an afternoon thunderstorm or two. These thunderstorms rarely
interfere with hiking itineraries and are not usually problematic. Of course,
thunderstorm safety should be practiced. The wildflowers at the higher
elevations should be all out by mid-July. Hiking conditions during this time
are often favorable, and it’s a great time to be on the trail. The shuttle to Malga Ra Stua, which is the starting point for the easier version of the itinerary, begins operating the first weekend of July and stops operating the last weekend of August. This means that there are days at the very beginning of July and at the very end of August where a taxi would be required to reach Malga Ra Stua, an alternate location to start the tour.
Early
September: The first snow of the winter usually falls in the
first week of September. The snow rarely sticks around for more than a day, but
the visibility can be very low, making navigation problematic on this one day.
Most days in early September are beautiful and perfect, and the thunderstorms
are less, but there is a higher risk of snowstorms and conditions that may
prevent you from completing your hike during this time. Many hikers have
incredible weather in September, but some do not. It’s simply a matter of luck.
The later you push into September, the higher the risk that unfavorable
conditions (usually snow, but sometimes extremely cold temperatures) can
interfere with your hiking itinerary. We notice that customers who are on the
trail beyond September 15th are much more likely to quit their hike
early due to conditions. In early September, the wildflower season is mostly
over, with the exception of brilliant bursts of fireweed that mark the end of
summer. The Malga Ra Stua shuttle is not running, so a taxi is required if you decide to do the easier itinerary and start at Malga Ra Stua instead of at Lago di Braies. The regular bus service from the end of the tour to Cortina d'Ampezzo may stop running as early as September 8th (the exact date changes each year and we don't know this date until June), so it may be necessary to arrange a taxi at the end of the tour.
In all
months, it’s reasonable to expect 1 to 2 rainy days on the trail.

Important
note about availability on the Alta Via 1: Many authors and bloggers have published
information that June and September are the shoulder seasons and are less
crowded on the Alta Via 1 than other times of the summer.
The word is out and now
huts tend to fill up faster in June and September than they do in late July and
August. In fact, for the past couple of years, August has had the most
availability for last-minute bookings. With that said, August is a busy time of
year for tourists in the area, so hotels in Cortina can be more expensive at
that time, and sometimes difficult to get.
The Alta Via
1 is a very popular route, and the huts are going to be full during the entire
season. If your goal is to avoid the crowds (although in most places the trail
does not feel crowded at all), then we recommend choosing a route that is less
famous, but just as, if not more, incredible. There are well over 800 mountain
huts in the Alps, and hut-to-hut possibilities are endless. Here are some great
