When to go to Torres del Paine, and how far ahead to book

Your travel times to Torres del Paine stay about the same all year. The flight from Santiago takes the same four hours in March as in December, and so does the drive from the airport to the lodge. The season changes two other things: which rooms you can still get, and how many hours of light your traveler has once they arrive.

The six-month rule for the holidays

December and early January sell out first. Book them at least six months ahead.

If a client calls you in September about this December, you will find the rooms other people passed on. The lodges you would pick for them went months ago. Work backwards from that and you get a simple rule: close holiday trips before June. After June, your client either moves the dates or accepts what remains.

Have that conversation in the first call, before you draft anything. A client takes "those dates are gone" far better on day one than after two rounds of proposals.

The flight needs the same urgency as the lodge. Puerto Natales, the airport you want, has few daily flights and they fill in high season. Book the flight first and build the rest around it. Why Puerto Natales and not Punta Arenas.

July is the exception on transfers

In July, ice on the roads slows everything down. You feel it most inside the park, where transfers between lodges and out to the trailheads stretch well past their summer times. The border crossing to El Calafate slows down too. If you are planning a winter trip, pad the days that include a transfer.

Pack for cold, even in January

Travelers from the northern hemisphere hear "summer" and pack for heat. Patagonia stays cold for most of the year. Summer brings good days, with sun and long evenings, but the wind stays with you in every season. Tell your client to pack layers and a proper shell for January. A traveler who arrives dressed for warm weather has a miserable first day on the trail.

Light is the seasonal difference that shapes the trip

Daylight changes far more than temperature does, and more than most clients expect.

In December the sun comes up around 5:30 and sets after 22:00, which gives your traveler about 16 and a half hours of light. They can hike all day and still eat dinner in daylight. In June the sun rises near 10:00 and sets before 18:00, under eight hours in total. That leaves a narrow window for the long hikes to the towers and the glaciers, which is what your traveler flew all this way to see.

The case for shoulder season

Most of your clients will ask for high season, because the photos they have seen come from high season. For one kind of traveler, it is the wrong recommendation.

October and April, at the edges of the season, bring a fraction of the visitors. A traveler who wants remoteness, who wants to feel they reached the end of the map, gets a different park in those months, and it looks every bit as good. A lot of luxury travelers in Patagonia come for that.

You pay for it in two ways. Fewer lodges operate, and the days are shorter. Check which lodges are open on your dates before you suggest it.

Ask before you give dates

Ask your traveler what they want from the trip before you offer any dates.

If they say they want to see the towers and take the photo, book high season and book it early. If they say they want to feel like the only people out there, recommend shoulder season and explain the trade. A search engine gives every client the same dates, while your advice can match the season to the traveler.

Once you have the season, the next decision is length. How many nights to plan in Torres del Paine.
