Day Trips from Selfoss: South Coast Options Within Reach

The Short Ring: Geysir, Gullfoss and Kerið

The classic Golden Circle loop is the easiest half-day from Selfoss and the one most visitors do first. Route 35 climbs northeast past Kerið, a volcanic crater lake with a small entry charge payable by card at the gate, then continues to Geysir, where Strokkur erupts every few minutes, and on to Gullfoss. Driving time is roughly an hour to Geysir and about 90 minutes to Gullfoss without stops, so a morning departure leaves the afternoon free. Go early: tour coaches reach Geysir from Reykjavík between 10am and 2pm, and the car park fills quickly in July and August.

Fuel up in Selfoss before leaving, since services thin out beyond Flúðir. Kerið takes twenty minutes, Geysir around an hour if you walk to the upper viewing points, and Gullfoss an hour including the lower path, which is often icy between November and March. If you only have one clear day, this is the route I would book around, because the driving is short and the weather risk is contained. Skip the paid geothermal exhibition at Geysir unless rain has already cancelled your plans.

Waterfalls and the South Coast Road

Route 1 east from Selfoss reaches Seljalandsfoss in about 55 minutes and Skógafoss in roughly 80. Seljalandsfoss drops over a cave and the path behind it is genuinely wet, so a waterproof shell is worth more than an umbrella. Skógafoss is the bigger spectacle, with 527 steps up the eastern bank and a viewing platform at the top. Continue twenty minutes to the Skógá river walk at the old bridge, or press on to Vík, another 35 minutes, for the black sand at Reynisfjara, where sneaker waves make the waterline genuinely dangerous.

This is a full day if you do it properly, and the round trip back to Selfoss is around four hours of driving on top of stops. The light in winter is short, so from November to January aim to turn around at Skógafoss rather than pushing to Vík. In June and July you can stretch to Vík and still be back for a late dinner. Stay overnight in Vík if you want Reynisfjara at sunrise, but otherwise Selfoss is cheaper and better placed for a second day.

Þingvellir, the South Coast and What to Skip

Þingvellir National Park is about 50 minutes northwest of Selfoss via Route 36, which puts it closer to town than most Golden Circle itineraries suggest. The Almannagjá gorge walk and Öxarárfoss take 90 minutes at an easy pace, and the Silfra car park fills early because of snorkelling groups. Entry to the park itself is free; parking is charged per vehicle by card. Combine it with the Geysir loop in one day rather than treating it as a separate trip, since the three stops sit within an hour of each other.

Two options I would skip from Selfoss: the Blue Lagoon, which is a 90-minute drive west and awkward to combine with anything else, and the Landmannalaugar interior route, which needs a 4x4 and is only reliably open from late June to early September. For a slower afternoon, the old dairy district in Selfoss and the riverbank walk along the Ölfusá take an hour and cost nothing. Book accommodation in Selfoss early for July and August, when south-coast rooms are the tightest of the year.
