What to book before a multi-day trek (and what to skip)

Updated June 2026

The honest short version: book trekking-grade travel insurance that explicitly covers your altitude and helicopter evacuation (this is the one thing you must not skip), book the trek, guide and permits direct with the operator — never through a middleman — and grab a data eSIM for maps and a lifeline when you land. An airport transfer and add-on tours are worth it only when the logistics are genuinely awkward; otherwise, save your money. Below is each one, with a straight verdict.

There's a long list of things you can book before a big trek, and most "what to buy" pages just want you to click everything. This one doesn't. A multi-day trek is already a real commitment of money and time, so the useful question isn't "what could I add?" — it's what actually earns its place, what's situational, and what's a waste. Here's our honest take on each, in plain order of how much it matters.

The one to never skip: travel insurance

If you read nothing else here, read this. Travel insurance that genuinely covers your trek is the single most important thing you book — and the one most people get wrong.

The problem is quiet but expensive: most standard travel policies exclude trekking above a certain altitude — often somewhere around 2,500–3,000m — and won't pay for a helicopter rescue. On a high route like Everest Base Camp or Kilimanjaro, a helicopter evacuation is the most expensive thing that can realistically happen to you, and it can run into the tens of thousands of dollars. If your policy doesn't cover your altitude and evacuation, you are effectively self-insuring against the one catastrophe a trek can throw at you.

So the rule is simple and non-negotiable: buy a policy that names your maximum trekking altitude in writing and includes emergency evacuation and repatriation. Read the altitude limit and the activity list before you pay — don't assume, and don't take a call-centre "should be fine" as cover. This is also the first thing to sort, before flights or gear, because it shapes everything else.

Verdict: Book it — for any multi-day or high-altitude trek. Just confirm it covers your altitude and evacuation. Check a trekking-friendly policy →

The trek itself: book direct, not through us

Here's the honest bit a lot of affiliate sites won't tell you: the trek, the guide and the permits are something you should book direct with a reputable operator — not through any booking middleman, including links on a site like this.

The climb is the one purchase where the details genuinely matter: how the company handles acclimatisation, whether their itinerary has enough days, how they treat and pay their porters, and how they answer your specific questions. That's a real conversation with a real operator, and it's worth having directly. Permits for popular routes (the Inca Trail, Kilimanjaro park fees, TMB refuges) are either booked by that operator or through official channels — there's no shortcut worth paying a third party for. We deliberately earn nothing on the trek itself; use our trek planner and the destination guides to choose well, then book the operator direct.

Verdict: Book direct — with a vetted operator. No affiliate link here, on purpose.

A data eSIM: small money, genuinely useful

An eSIM gives you mobile data the moment you land, without hunting for a local SIM at the airport or paying brutal roaming rates. On a trek that means offline maps you've pre-downloaded actually stay useful, you can message your operator, and you have a lifeline in the trailhead town and wherever there's signal on the trail. It's cheap, it installs before you fly, and it removes a real first-day headache.

The honest caveat: do not rely on it for safety high on the mountain. Signal vanishes on most big treks, which is exactly why insurance with evacuation cover (above) and your operator's communications (a sat phone or radio) are what actually keep you safe up there. An eSIM is a convenience that's well worth its small cost — not a substitute for proper cover.

Verdict: Worth it — cheap, useful from the moment you land. Just don't treat it as a safety line. Get a travel eSIM →

Airport transfer: only when the logistics are awkward

A pre-booked airport transfer — a driver waiting at arrivals, fixed price agreed in advance — is genuinely worth it in specific situations: you land late and jet-lagged, you don't speak the language, the trailhead town is a long drive away, or you simply don't want to negotiate a taxi at midnight after a long-haul flight. In those cases the certainty is worth the modest premium.

But be honest about when you don't need it. Many trek operators already include airport pickup in the package — so check before you double-book and pay twice. And where there's a cheap, official taxi rank right outside arrivals and a short hop into town, a separate transfer is money you don't need to spend.

Verdict: Maybe — book it for awkward arrivals; skip it if your operator includes pickup or a cheap taxi is right there. Price a fixed transfer →

Tours and extra days: a nice-to-have, easy to skip

Adding a city tour or a day trip either side of your trek can be a lovely way to use a spare acclimatisation day or a buffer day before you fly home — a guided wander around the gateway city, a market, a short excursion. If you've got the time and the curiosity, it's a pleasant extra.

It is, though, the most skippable thing on this page. It has nothing to do with whether your trek goes well, and after a hard multi-day walk plenty of people just want to rest, eat and do nothing. Book it only if you actively want the extra day out — never out of a sense that you "should" fill the time.

Verdict: Skip unless you want it — pure nice-to-have, irrelevant to the trek going well. Browse tours & day trips →

The honest "skip" list

A few things worth not spending on before you go:

• A full set of brand-new gear you'll use once. The bulky, expensive items — a four-season sleeping bag, an insulated summit jacket, poles — are often cheaper to rent at the trailhead than to buy. Buy and break in the personal-fit kit (boots, base layers); rent the rest.
• Premium "fast-track" airport and lounge add-ons. Almost never relevant to a trek, and easy to talk yourself into. Put the money toward more days on the mountain instead.
• A second booking for anything your operator already includes. Read your package carefully — transfers, park fees, sometimes a hotel night are frequently bundled in. Don't pay twice.

The quick comparison

Cost bands are rough, indicative ranges to show relative scale — actual prices vary widely by country, season and operator. Always check the current price before you book.

So, in what order?

If you want a simple sequence: (1) sort trekking-grade insurance first, because it shapes the whole trip; (2) choose and book your trek direct with a good operator — start with the trek planner and the guides below; (3) add an eSIM; (4) decide on a transfer once you know your arrival and what your operator includes; and (5) add a tour only if you genuinely want the day. Everything else, you can safely leave alone.

Next steps: use the trek planner to shape your trip, then read up before you commit — what Everest Base Camp is really like, the Kilimanjaro routes compared, how to avoid altitude sickness, and the honest packing list (with what to rent, not buy).
