Gravel Travel · Reykjavík
Gravel Travel collects you in Reykjavík at 9:00, drives the south coast with a coffee stop in Hvolsvöllur, then takes a lifted 4x4 into Þórsmörk and back. It is the one shared Þórsmörk day on Viator with city pickup, which saves you the 1.5-hour drive to a base camp, but it is new and has only two reviews.

Most good Þórsmörk days start in the south and leave you to get there. Gravel Travel does it the other way round: pickup from 32 points in Reykjavík at 9:00, drop-off at bus stop 12 (Höfðatorg) in the evening. You can also join on the way, in Hveragerði, Selfoss, Hella or Hvolsvöllur. The route crosses the Hellisheiði plateau, stops for coffee in Hvolsvöllur, then leaves the Ring Road at Seljalandsfoss for F249 and the river crossings into the reserve.
The listing keeps the inside-the-valley program loose. The two reviews so far name Nauthúsagil ravine and the cliffs of Stakkholtsgjá, and a family wrote about an "extended F350/Excursion", a big lifted Ford rather than a classic jeep. The vehicle has Wi-Fi and air conditioning. Expect short walks, not a hiking day.
Be clear about the trade-offs. Lunch is not included, so pack one. A group of up to 19 is large for Þórsmörk; Midgard caps its super jeep day at 14. And two reviews is a thin record next to the hundreds behind the south-coast operators. If you have a car, the Hvolsvöllur start is cheaper per hour in the valley. If you don't, this is the simplest shared option there is.
Choose one of 32 pickup points when you book. South-coast guests can join along the route.
East on Route 1 across the plateau, with a coffee break in Hvolsvöllur.
Off the tarmac at Seljalandsfoss and through the glacial rivers into Þórsmörk.
Stops and short walks in the reserve; guests name Nauthúsagil and Stakkholtsgjá. Bring your own lunch.
Drop-off at bus stop 12, Höfðatorg, Þórunnartún 6.
★★★★★As a photographer, this day was a dream. The light inside Nauthúsagil ravine was otherworldly, and the dramatic cliffs of Stakkholtsgjá were perfect. [...]
★★★★★From the minute our extended F350/Excursion pulled up, I knew this was going to be the perfect trip for my family with two boys! Our guide was amazing and she knew exactly what would keep two young boys entertained all day. [...]

Yes. This Gravel Travel day picks up from 32 points in Reykjavík at 9:00 and returns about 10 hours later. The private trips with Glaciers and Waterfalls and Arctic Trucks also collect you in the city, at a per-group price.
No. Lunch is listed as not included. There is a coffee stop in Hvolsvöllur on the way out where you can buy food, but bring a packed lunch.
Up to 19 travellers. That is more than the south-coast operators: Midgard takes 14 and Southcoast Adventure 15.
It is a newer listing with two reviews, both 5 stars. The operators with long records start in the south; read our day trip from Reykjavík guide for how they compare.
