Best time to visit Interlaken

The useful way to think about the Interlaken year is not temperature. It is three things: how long the light lasts, what the water looks like, and which of the thirteen trips are selling on the day you arrive. Those three move together, and they move in a way that is easy to plan around once somebody writes it down.

Light. In midsummer the valley floor stays usable long after the last gondola down, which is why a full day can hold two of our four kinds of day — a morning at Mount First and an afternoon on the water, or a gorge in the morning and a flight in the evening air. In deep winter the light goes early, and that is not only a loss: $122 is built on it. That trip includes the gondola ticket up and the guide, and the run itself happens in the dark, which is a thing you simply cannot buy in July.

Water colour. Lake Brienz is the one people photograph, and it is described on its own listing as turquoise — $142 sells a paddle past towering cliffs, the 12th-century Ringgenberg Castle and the mouth of the River Lütschine. That colour is a product of glacial meltwater, so it is at its most saturated in the warm months when the melt is running. In winter the same lake goes still and dark, which is exactly what $172 is selling: the listing calls it the breathtaking silence and atmosphere of the lake in winter, and puts you in a fully sealed expedition drysuit, neoprene boots and thick warm socks to enjoy it.

What is open. This is the part with a published date on it, and it matters more than any weather forecast. $51 is a day pass for the boats on both lakes, and the listing is explicit that the Lake Brienz half runs only during summer, from the beginning of April until mid-October. Outside that window the same ticket still covers Lake Thun. Everything else on this site either runs through the year, like the gondola and the glacier canyon, or exists only because it is winter.

What you will not find on this page is a table of degrees and rainfall. Those numbers are not published on the listings we sell, and inventing them would be the easiest way to have you dressed for the wrong mountain. What the operators do publish is what is included, what the gear is, and when the boats stop — and that is what the rest of this page is built from.

Spring. The season turns on one date: from the beginning of April the Lake Brienz boats join the day pass, and Interlaken becomes a place with two navigable lakes instead of one. $51 is the ticket that notices this, and at that fare it is the cheapest way to spend a whole day moving. Up the mountain, $89 is already running — round-trip cable car and the First Cliff Walk are the parts that work in any month, while the hike onward to Bachalpsee, which the listing calls the most beautiful lake in the Alps, is a walk that wants the snow off it.

Summer. Everything is open, which is the whole argument for coming now. All four kinds of day are available on the same afternoon: $89 for the gondola and the Cliff Walk, $51 for both lakes, $190 for the gorge — a 10-minute drive from the base in Interlaken, a 10-metre rappel to begin, with equipment, guides and hot showers back at the base — and $222 for the flight, which at 2,580 reviews is the most tested thing anybody does here. Lake Brienz is at its most turquoise, so $142 and $147 are at their best: the jetboat is a 45 to 50 minute run that passes the 500-metre-high Giessbach Falls, and it is marked wheelchair accessible.

Autumn. The boats hold on until mid-October, and the weeks either side of that date are the quiet version of summer — the same gondola, the same gorge, fewer people on the Cliff Walk. $26 is a good autumn ticket precisely because much of its route runs through rock galleries and tunnels, so a grey afternoon costs you nothing, and entry to the Crystal Museum comes with it. Flights keep running: $209 holds the highest rating on this site at 5.0 and puts you over the Lauterbrunnen cliffs and waterfalls for up to twenty minutes.

Winter. Three trips exist only now, and they are the reason a winter visit is not a consolation prize. $172 gives 2.5 hours of instruction with a bilingual instructor on the Bodmi beginner slopes at Grindelwald, with ski, boots and helmet rental and the magic-carpet lift ticket included, under the north face of the Eiger. $122 takes you up by gondola and sends you down a moonlit run with a guide, sled and boots provided. $172 is a small-group paddle on a silent Lake Brienz, and the listing states plainly that it suits non-swimmers and beginners. Meanwhile the day tickets keep working: the gondola still climbs, the gorge is still open, and the day pass still covers the Lake Thun boats.

If you want the most choice. Come while the Lake Brienz boats are running, between the beginning of April and mid-October. That is the only period when $51 is a two-lake ticket rather than a one-lake ticket, and it is the period in which the paddling, the gondola, the gorge and the flights all sell together. Nothing else on this page comes close on breadth.

If you want the water at its best. The warm months, and specifically the kayak. $142 holds 4.9 from 265 reviews, runs in small groups at a 6:1 client to coach ratio, and takes you past the cliffs, Ringgenberg Castle and the mouth of the River Lütschine. The operator also states that it runs in most conditions, rain and snow included, and reschedules or refunds in full if a tour cannot go ahead — which removes most of the reason people avoid booking a paddle in advance.

If you want the quietest version. Winter, and specifically $172 at 4.9 from 281 reviews. A fully sealed expedition drysuit, neoprene boots, thick warm socks, a small group and a digital photo and video package are all in the fare. The listing sells silence, and in a valley that sees this many visitors, silence is the rarer product.

If you are coming for one thing only. $222 is the most reviewed trip on this site by a distance — 2,580 reviews at 4.9 — and it runs through the year with pilot, equipment and transport included. The season changes what is underneath you, not whether it happens.

The verdict. For a first visit, aim at the window the boats define: any time from April to mid-October, when $51 covers both lakes and every one of the four kinds of day is buyable on the same afternoon. If you have already had that summer, come back in winter instead and buy the three things summer cannot sell you: $172, $122 and $172.

1. Buying the boat day pass out of season and expecting both lakes. $51 states it: the Lake Brienz boats run only during summer, from the beginning of April until mid-October. Outside that, the same ticket is a Lake Thun ticket.
2. Treating winter as the off season. Three of the thirteen trips here only exist in winter, and one of them, $172, holds 4.9 from 281 reviews.
3. Booking the short trips last. The 50-minute jetboat and the 90-minute flight are the easiest things to slot into a busy day, which is exactly why they go first in high season. Both ask you to book in advance — the jetboat at least an hour ahead.
4. Planning around a forecast instead of the inclusions. $142 runs in most conditions including rain and snow, and $26 spends much of its route in rock galleries and tunnels. A grey day removes far less than people assume.
5. Assuming the gondola ticket is only worth it in summer. $89 is a day ticket covering the round-trip cable car and the First Cliff Walk, and both work with snow on the ground. The Bachalpsee hike is the part that is seasonal.
