Hallormsstaðaskógur

Typically September 15–October 5

A highland river valley walled in by three glaciers, Eyjafjallajökull, Tindfjallajökull and Mýrdalsjökull, warm enough in its own pocket microclimate to grow downy birch scrub that most of interior Iceland can't support. Reached by unbridged river crossings or the last F-road buses of the season, usually running through mid-September, right as the birch and dwarf willow turn gold and rust.

Iceland's tallest native birch grows in Bæjarstaðarskógur, a stand inside Vatnajökull National Park reached by a rough 16km round-trip trail across the Morsá river footbridge. Closer to the visitor center, the short climb to Svartifoss passes through more accessible birch woods that gold up through September against black basalt columns and the Skaftafellsjökull glacier tongue.

Iceland's straightest, tallest native birch grows here in Fnjóskadalur valley near Akureyri, some trunks over 12 meters where most Icelandic birch stays shrubby. A dozen kilometers of forest trails and campsites reward an easy walk, and North Iceland's colder interior climate turns the canopy gold earlier than the south, typically through the first half of September.
