Locale: Vatnajokull National Park (formerly Jokulsargljufur National Park)
Hafragilsfoss at 27m tall 91m wide is the third of a series of waterfalls on the glacial river Jökulsá á Fjöllum (downstream of both Selfoss and Dettifoss).
Dettifoss is a 44m tall 100m wide waterfall on the Jökulsá á Fjöllum between Selfoss and Hafragilsfoss sourced by the vast Vatnajökull Glacier in North Iceland.
Selfoss is an 11m horseshoe-shaped waterfall on Jökulsá á Fjöllum River upstream from the mighty Dettifoss reached by a slight extension of the Dettifoss hike.
Urridafoss, Katlar, and Rettarfoss
Urridafoss (Urriðafoss), Katlar, and Rettarfoss (Réttarfoss) are all features of the canyon Jökulsárgljúfur further downstream of waterfalls like Dettifoss.
Holmafossar (Hólmafossar) is a fairly high-volume cascade tumbling on a tributary to the Jökulsá á Fjöllum River accessed by a lightly-used 2.6km return hike.
