What to do in Reykjavik this week

If the weather turns, this is one of the easiest ways to keep an Iceland trip feeling dramatic. Guided visits take you through a long lava tube shaped by ancient eruptions, with striking rock textures and seasonal ice formations adding to the atmosphere. It suits first-time visitors who want geology without a demanding hike, and it pairs well with a slower afternoon back in the city.

This is the kind of outing that breaks up a week of transfers and sightseeing nicely. At the farm, the focus is on meeting Icelandic horses in a more personal setting than a large group excursion. It works well for families and for visitors who want countryside scenery close to Reykjavik, especially if you would rather trade adrenaline for a calmer half-day outdoors.

Silfra is not a casual dip, but for confident adventure travellers it is hard to forget. Tours bring you into the fissure at Þingvellir, where the water is famously clear and the setting feels unlike anywhere else on a Reykjavik day trip. Save this for a day when you want your main activity to be the headline, and be ready for cold conditions even with specialist gear.

Not every week needs to be packed with long excursions. Old Harbour House works well as a practical anchor in the city, especially if rain has you adjusting plans by the hour. The location near the water makes it easy to fold into a harbour walk, and the food-and-drinks setup gives you an easy fallback when you want something low effort between bigger outings.

If this week's weather opens up, this is the outing to watch. Tours toward Fagradalsfjall focus on the stark, recently shaped lava fields that have made the area such a draw. It is a strong fit for travellers who want a sense of Iceland's restless geology and do not mind a more exposed outing. Pair it with an easier city plan the next day.

Even in a week shaped by daylight touring, Aurora Basecamp offers a different angle on Iceland travel. It makes the most sense for visitors who like structured, specialist experiences rather than general sightseeing. Keep it in mind if you want to balance daytime excursions with something more atmospheric and evening-oriented, especially outside the city centre.

Silfra appears more than once for good reason: it is one of the region's defining adventure outings. This operator focuses on the same remarkable fissure setting at Þingvellir, where visibility and the sense of place do most of the work. Choose it if you are comparing providers for a dedicated snorkeling or diving day, and leave room in your itinerary to recover afterward rather than cramming in extra stops.

If you are comfortable planning around conditions, the hiking area itself gives you a more stripped-back way to encounter the Fagradalsfjall landscape. The appeal is the setting: broad lava fields, exposed terrain and a real sense of recent geological change. It is more about being out in the environment than joining a polished attraction, so it suits independent-minded visitors with decent footwear and flexible timing.

For visitors who prefer straightforward logistics, Reykjavik Excursions can be useful simply because it covers a lot of ground from the city. This is less about one singular attraction and more about convenience: booking an outing, getting out of town efficiently and keeping your week organised. It is worth considering if the rain has you changing plans and you want a dependable departure point rather than improvising every day.
