How to Get to Tröllafoss#

Tröllafoss lies within reasonable driving distance of Reykjavík and regional roads leading north. Most visitors reach it by car on well-maintained rural routes; always check road conditions and weather forecasts before driving in Icelandic highland regions.

Tips for Visiting Tröllafoss#

  • Walk upstream a short distance from the main falls viewpoint to find less visited cascades and better framing for long-lens photography.
  • Visit in late spring for higher flows from meltwater; summer can be lower but warmer for walking.
  • Bring waterproof layers: spray from the falls can soak clothing even on calm days.

Best Time to Visit Tröllafoss#

Best seen in late spring and early summer when meltwater swells the falls; avoid winter when access is icy.
