Bláhnúkur is the one worth the legs
Bláhnúkur — Blue Peak — is the dark cone immediately behind the hut, and Ferðafélag Íslands puts the summit at 945 metres, with a marked route of four kilometres and 330 metres of ascent taking about three hours. The path starts east of the hut and crosses the Brennisteinsöldukvísl before climbing. From the top you look down on the whole colour field: rhyolite ridges in rust, rose and sulphur on every side, the black spill of Laugahraun below, and on a clear day glaciers on the horizon. The climb is short but persistently steep on loose scree, and the descent needs more care than the ascent.
Grænagil and the obsidian field
The gentlest walk from the hut is also the strangest. Laugahraun is an obsidian-rich lava flow from an eruption around 1477, and it has barely weathered — a jumble of glassy black blocks that catch the light, with marked paths threading between them. It takes well under an hour to walk out into it and back, and it is the right choice if you arrived by bus, want to bathe, and have a fixed departure time. Grænagil, the green gorge, runs along the edge of the flow and makes a natural descent route off Bláhnúkur, so many walkers climb the peak and come down through the gorge rather than retracing the ascent.
Brennisteinsalda and the first kilometre of the Laugavegur
Brennisteinsalda — Sulphur Wave — is the streaked, steaming rhyolite mountain south of the campsite, and the path to it is the opening section of the Laugavegur trail. Walking out to it and back is a good way to see what the long trek looks like without committing to it, and the ground underfoot changes constantly: obsidian, then pale sulphur crust, then ochre and green rhyolite, with vents releasing steam beside the path. Most walkers combine it with Bláhnúkur as a loop of roughly nine to ten kilometres and around six hundred metres of total ascent, taking four to six hours at a steady pace.
What three hours actually buys you
A super-jeep day tour typically gives you about three hours on the ground, and the scheduled buses give you a fixed window set by the timetable. That is enough for one substantial thing plus a soak, not two. Realistically: the Laugahraun loop and a long bathe; or Bláhnúkur at a brisk pace and a short bathe; or the walk out to Brennisteinsalda and back with time to spare. The Bláhnúkur–Brennisteinsalda loop does not fit a three-hour window and should not be attempted against a departure deadline. Decide before you set off, and tell your guide or note the bus time, because there is no later service.
Snow, cloud and the case for turning back
You are at around 550 metres at the hut and above 900 at the summit of Bláhnúkur, inside a reserve that lies largely above 500 metres, and the weather behaves accordingly. July daytime figures for Landmannalaugar typically sit near 10°C at the high point and around 5°C overnight, with rain on roughly a third of days. Snow patches survive on the high ground well into July, and cloud can close over the tops within minutes, erasing the marked route. Carry waterproofs and a warm layer regardless of the forecast in Reykjavík, wear boots with real grip, and treat an unexpected whiteout on scree as a reason to descend.
