A guided swim in a flooded fissure at Þingvellir, no diving licence needed: 17 tours compared, with each operator's height, weight and age limits.
Yes, with a guide and no diving licence: you float on the surface in a dry suit or a thick wetsuit.

Silfra is a fissure in Þingvellir National Park, fed by one of the main springs of the area. You go down a metal staircase, follow your guide through its deep canyons, and finish in a shallow lagoon. The time in the water runs from 25 to 50 minutes, depending on the operator.
Between which plates? The sources differ. Visit Iceland and the operators say North America and Eurasia. The national park says “the North American and the Hreppar micro plate”. Either way it is a rift that is still opening, by about 2 cm a year according to Visit Iceland.
5 operators sell it on site from €117. What differs is the suit, the time in the water, what you pay on top, and who they accept.
At Silfra itself, or with a pickup in Reykjavik, about 60 km away.

The five tours at Silfra, side by sideEvery Silfra tour on GetYourGuide
Dive.is says there is no best or worst time, and the water stays about the same all year.
2 to 4 °C all year, says Dive.is; about 3 °C, says Troll.
This is what changes. Troll says you change outdoors, whatever the weather, and advises a hat and gloves, especially in winter. Diving Island says you change indoors, and Dive.is lists a heated van.
Every tour here can be cancelled free up to 24 hours before, so you can book and then watch the forecast.
About 3 hours on site, with 25 to 50 minutes in the water.

A safety briefing and the suit: 30 minutes at Troll, an hour at Dive.is. The neck and wrist seals must fit snugly.
A short distance in full gear, which can be awkward, to the metal staircase.
You follow your guide through Big Crack, Hall and Cathedral to the Lagoon. There is a mild current, and you swim against it near the end.
A hot drink on nearly every tour. Most include photos; check yours under “Compare in detail”.
On most tours: from age 12, from 145 or 150 cm and 45 kg, up to 120 kg, if you can swim.
From 135 to 150 cm at the lowest, depending on the operator. Troll's own page gives two figures. See every limit, operator by operator.
45 kg at least on most tours, and 120 kg at most, up to 130 kg at Diving Island.
From 12 on most tours. The upper age runs from 60 to 70 where a page gives one, and some ask for a doctor's clearance first.
Pregnancy is ruled out everywhere we read a list. Most operators also rule out heart or lung problems and epilepsy, and ask for a signed medical statement.
Your limits, your clothes, and how you get there.

Check height, weight and age for the operator you pick, not in general. They differ, and a guide can turn you away on the day.
Troll asks for warm socks, thermal leggings and a thermal shirt under the suit, and no jewellery. Regular glasses do not fit under the mask.
Silfra is about 60 km from Reykjavik. With no car, book a tour with transport or a pickup option. With a car, you park at P5.
About 2 to 4 °C, according to the operators, and your head and hands feel it.
A dry suit keeps most of you dry, but Troll warns that small leaks can happen at the neck and wrists, so bring spare thermals.
If your hands are your worry, Diving Island is the one that says it gives dry gloves. Adventure Vikings also offers a 6 mm wetsuit, for those who choose to get wet.
That's yours to weigh: from €117 for under an hour in very cold water, in a place operators advertise for its visibility of 100 m or more.
From €117 at Silfra and from €181 with transport from Reykjavik. Parking, if you drive, is 1,000 ISK.
Every tourOn most tours, yes: several list non-swimmers as not suitable, and Troll asks that you are comfortable swimming against a mild current.
Every limitVery cold water and a tight suit are not for everyone. The park says those who go in do so at their own risk. Read the health rules before you choose.
What we knowThe park's rules cover individuals too: they register, sign a liability statement and pay a visitor fee, and the park supplies no gear.
You can visit the area without going in, but the underwater view is what the tours sell.
The fissure2 h 30 to 3 h at Silfra, and 4 h 30 to 6 h with transport from Reykjavik.
Yes: 3 tours here do both in a day, from €259. Þingvellir is also where those circuits stop.
Check the limits, then pick your tour.
