Reykjadalur

STANDARD // RT
Full Route Report

Reykjadalur translates to 'Steam Valley,' an aptly named geothermal area where a moderate hike leads to a naturally heated river. Located near the town of Hveragerði (approx. 45 minutes from Reykjavík), this 7.4km round-trip route is a popular destination for those seeking an authentic outdoor soak. The trail ascends through rolling green hills, passing active geothermal features including mud pots and steaming vents. At the end of the well-marked path, cold mountain water merges with geothermal streams to create a swimmable river with various temperature zones. Visitors typically spend time soaking in the warm currents before returning via the same route.

The HikeMetrics Hazard Scale is a proprietary 5-point classification system that evaluates hiking routes across five dimensions: physical demand, technical complexity, altitude exposure, weather risk, and rescue accessibility.

Unlike generic star ratings, the Hazard Scale is calibrated against altitude profiles, elevation gain per day, and logistical isolation factors — making it the most precise route classification system available.

Route A // Hazard Verdict
Highway Lakes — Blindsee & Weißensee
LOW // ACCESS
slippery roots near water: The path around the Blindsee is narrow and features many wet tree roots.
Route B // Hazard Verdict
Reykjadalur
STANDARD // RT
geothermal features: The valley is geothermally active, with boiling mud pits and steam vents located near the trail. Some pools exceed 80–100°C and present a severe burn risk.
hypothermia after swimming: While the water is warm (~38°C), high wind chill and low air temperatures can lead to rapid cooling upon exiting the river.
