Detailed Info

Háifoss is a moderate to high volume waterfall found along the Fossá as it plunges from a high plateau into a massive canyon to meet the valley of the Þjorsá further downstream. The river actually splits into two channels about 4/5th of a kilometer upstream from the falls, and when they reach the rim of the canyon, form two side-by-side waterfalls. The larger volume channel creates Háifoss, which takes the form of a nearly sheer plunge of 396-feet in height, and the smaller volume channel is individually known as Granni ("The Neighbor" in Icelandic). A smaller series of cascades occur about half of a kilometer upstream from the top of Háifoss, the majority of which cannot be seen in tandem with the falls. Because the Fossá is a river of signficant size, the segmenting of the stream does not impact the quality of either waterfall. During the spring and early summer months when the winter snow is melting at its fastest rate, both falls swell to impressive volumes and create a surround-sound roar which echoes throughout the canyon.

Until recently Háifoss was considered to be the second tallest waterfall in Iceland, but with the "discovery" of Morsárfoss near Skaftafell it was bumped to third by most conventions. However, upon our trip to Iceland in August 2014 we found this to be inaccurate, as there are actually a number of waterfalls which are taller in terms of overall height. With the data we currently have Háifoss places 9th on the list, with its sibling Granni coming in 7th (it could be argued that by counting the cascades upstream of Háifoss, it would actually be the taller of the two, but the distance between the falls and cascades was too great, we felt). This does not take into account the literally dozens and dozens (if not hundreds) of small volume waterfalls which can be seen stair-stepping down mountainsides throughout the more rugged parts of the country.

History and Naming

Háifoss is the Official name of this waterfall.

Háifoss translated to english literally means High Falls - an uncreative but certainly an apt name for the falls, however its pronunciation is closer to "HAU-i-foss". Apparently the falls were not named at all until some time in the late 20th century (we'd guess the early 1980s, but have not been able to find an exact date).

Our Thoughts

Though it may not quite place as high on the list of Iceland's tallest waterfalls, there is no doubt that Háifoss is one of Iceland's most impressive waterfalls. Unlike most of the other "tall" waterfalls found throughout the country, Háifoss has that unique combination of both height and volume that so few "tall" waterfalls have. Pair this fact with the huge, gaping canyon which the falls drop into and you have the formula for an absolute must-see attraction for any visitors to Iceland.

Photo Tips

Háifoss and its canyon are exceptionally photogenic, and with the exception of the unsightly power lines to the northeast, there is not a single bit of human intrusion visible when photographing the falls. There are multiple different angles available along the rim of the canyon, both looking upstream and down, so be sure to spend some time investigating the options - the view looking downstream is particularly spectacular at sunset. The more ambitious can seek several additional compositional options by hiking to the base of the falls from Stöng, though considering the heavy spray from the falls, it will likely be more difficult to achieve a clean shot at the base of the falls (the perspectives are no less impressive). Háifoss faces southwest and should see direct sunlight for the majority of the day, falling into total shade by the late afternoon hours.

Location & Directions

Coordinates:   64.208, -19.6877
Elevation:   0 feet

Despite being easy to access, finding Háifoss is actually a bit of a task due to poor signage (at least as of August 2014). Take Highway 1 east from the city of Selfoss and turn north on to Route 30 (just over 3km west of the bridge over the Þjorsá). Follow Route 30 north for 18.4km then turn right onto Route 32 and continue for another 43km then turn left onto an un-numbered gravel road where a sign points to a guesthouse (there had apparently been a sign marking Háifoss in the past, but it was not there when we visited). If you pass the power plant and cross the Þjorsá you've gone 5.5km too far. On the gravel road, drive 500m then bear right - here there is a sign marking the falls - and continue for another 6.6km, then turn left again where a sign points to the falls, to the parking area in another 500m. The road to the falls is rough and while it did not appear to be classified as an F road (restricted for non 4wd-vehicles) it should be driven very carefully. From the parking area, a short trail leads along the rim of the canyon for 500m to the best views of the falls. Additionally, it is possible to hike about 8km to the base of the falls from Stöng (see link to Gjáinfoss below).

By The Numbers

The information presented in this table is meant to help identify and clarify the physical aspects of the waterfall for comparative purposes. While we try to ensure this information is as accurate as possible, sometimes it will prove necessary to either estimate or flat out guess at certain characteristics where either enough information isn't readily available, is not known, or we were not able to confirm a given trait upon surveying. This information may be changed at any given time to ensure accuracy.

Total Height

The Total Height listed for the waterfall represents the difference in elevation from the top of the uppermost drop, to the bottom of the lowermost drop of the waterfall, including all stretches of interstitial stream in between. Stream between two tiers of a waterfall is counted in its overall height regardless of whether or not that section of the stream would be legitimately considered a waterfall on its own right, were it to be isolated. Waterfalls with only one drop will of have the height of only the single drop listed here.

Tallest Drop

The Tallest Drop figure represents the height of the largest single drop within a multi-stepped waterfall. Waterfalls with only one drop will have the total height of the waterfall repeated here.

Num of Drops

The Number of Drops in a waterfall is a tally of the total number of distinct drops which make up the waterfall. Stretches of interstitial stream in between two or more distinct drops of a single waterfall are NOT considered to be distinct drops of the waterfall unless the section of stream in question would otherwise qualify as a waterfall were it to be isolated.

Avg Width

The Average Width of the waterfall represents the breadth of the waterfall from bank to bank under typical flow conditions, or if the waterfall has been Cataloged, under the conditions which it was most thoroughly surveyed. Often this number will be approximated because of a lack of approachability to many waterfalls. We often utilize Google Earth to measure the width (where imagery is of sufficient quality and resolution to allow it.

Maximum Width

Maximum Width represents a hypothetical measurement of roughly how wide a waterfall could get during peak streamflow or flood conditions. For smaller waterfalls, this figure will generally not differ much from the Average Width measurement, but for broader waterfalls - especially those that feature a crest that isn't constricted - this figure can at times be consideraby larger. Like the Average Width measurement, this measurement will take into account the difference in width at the top and bottom of the waterfall as much as possible, but will often be made based on the width of the crest of th falls alone.


The Pitch of a waterfall is an estimated - often very roughly - measure of the average slope or steepness of a waterfall. The Pitch figure only takes into account sections of stream which are actively falling. Pools or stretches of level stream in between two or more successive drops of the falls will not factor in this figure. As an example, a waterfall which features two truly free-falling leaps separated by several dozen yards of flat stream will have a Pitch of 90 degrees. Similarly, a waterfall with two drops separated by a pool, one with a true free-falling drop, and one with a Horsetail type fall will average the two, so while the Plunging drop has a Pitch of 90 degrees, if the Horsetail drop has a Pitch of 45 degrees, the total Pitch will be roughly 67 degrees.


The Run of a waterfall is a measurement representing the total linear distance on the ground between the top and bottom of a waterfall. This figure is not often easy to establish with a high degree of precision and as such will often be estimated. Waterfalls with a longer Run will usually either be less steep, often cascading type waterfalls, or will feature multiple steps separated by shorter stretches of a more gradual gradient streambed.


The system of classification of waterfall forms we use is a heavily modified derivative of the classifications outlined by Greg Plumb in his "Waterfall Lover's Guide to the Pacific Northwest" books. While plumb uses eight distnct forms, we wanted further granularity and opted to break down the hierarchy twofold: first based on the overall pitch of the waterfall, and then based on what shape the fall takes as it makes its descent. There are five primary Categories of falls in this system: Plunge, Horsetail, Steep Cascades, Shallow Cascades, and Rapids. Additional deliniation is then applied depending on characteristics such as the breadth of the falls, whether it splits into two or more channels, whether it falls in multiple successive drops, etc. For more information on our waterfall form classifications, see the Help page.


The watershed which a waterfall occurs within, if it is specified, will be based on the ultimate distributary watercourse to the ocean. For example, Washington's Palouse Falls occurs along the Palouse River - which is a tributary to the Snake River, which is itself a tributary to the Columbia River, which ultimately enters the Pacific Ocean, so Palouse Falls would then fall within the Columbia River watershed. Streams which empty directly into the ocean, or into a minor basin which then empties to the ocean will often have this field left blank.


The name of the watercourse which the waterfall occurs along. If the watercourse is not known to have an officially or colloquially recognized name, this field is left blank.

Avg Volume

The volume of water present in the stream at the location of the waterfall. This is often the most difficult figure to pin down because accurately measuring streamflow is not a simple process. We will rely on USGS data as much as possible, and attempt to take into account seasonal fluctuations in stream levels if possible. There is no guarantee that this figure will be accurate, and in cases where there is no USGS data to use, it may be a very, very rough estimate at best.


If known, the primary source of the watercourse which produces the waterfall will be listed here. This is helpful in determining whether a waterfall may flow more consistently during certain periods of the year - streams which originate in Springs, Lakes, or Glaciers will often flow more consistently throughout the year than those fueled by simply Runoff. The source of the stream may also be either unknown or undetermined.

Flow Consistency

A rough estimation of how many months out of the year the stream which produces the waterfall will actually hold water. The vast majority of waterfalls featured on this website will technically be truly perennial waterfalls (those that flow all year long), but some may see their flow dwindle greatly in the late summer months. This figure will not take into account the winter months when the waterfall may freeze, because in such cases the waterfall will very often be inaccessible. Entries which specify a Flow Consistncy of 12 Months should in general have an acceptable flow at any time of year (but may be better during certain periods - see below).

Best Flow

A general estimate of the best period of the year during which time the falls will be considered at optimal conditions, or flowing at their best. There may be variance within the range specified where the flow will be better or worse, but visiting at any time in the range specified (if available) will generally present the waterfall in its best light.



Cataloged Icon
Waterfalls which are Cataloged we have visited and surveyed in person. Statistical information should be quite accurate (for the most part), and exact measurements will often be available (information is not guaranteed to always be up to date). Detailed information, directions, and photographs will almost always be available.
Confirmed Icon
Confirmed Waterfalls are known to exist, should be relatively accurately mapped and geotagged, and the statistical information available will often be dependable. If height information is presented, it may be estimated but should be accurate. Directions will not likely be available.
Unconfirmed Icon
Unconfirmed Waterfalls are often marked on a published map, but we have yet to confirm the exact location and / or whether or not its stature is significant enough to qualify for listing in the database. Statistical information may be estimated and may be inaccurate. No directions.
Unknown Icon
Waterfalls marked as Unknown are either suspected to exist based on heresay or a hunch, or we have received unverified information suggesting a waterfall may exist near the location provided but cannot corroborate it in any way. Geodata may not be accurate, the location may not be known at all, and statistical information will be estimated and highly inaccurate.
Inundated Icon
Inundated Waterfalls have been submerged beneath lakes or reservoirs, usually a result of impoundment of a river behind a dam, and most often no longer functionally exist (there may be rare exceptions). We maintain records for these features out of historical importance.
Subterranean Icon
Though not common, some waterfalls can be found entirely underground within cave systems. Access to subterranean waterfalls can vary from easy via developed walkways to requiring a high level of extremely technical spelunking skill, including familiarity with ropework and a distinct lack of claustrophobia.
Disqualified Icon
Waterfalls which have been marked as Disqualified do not have the necessary stature or features to qualify as a legitimate waterfall according to our criteria. We will maintain records for entries with this status where the feature is well known and / or may have been historically referred to as a waterfall at some point in time.
Posted Icon
Posted Waterfalls are known to exist, and we may have a large amount of information associated with them, but are located on private property and are not legally accessible to the general public. Accessing waterfalls with this status should not be attempted without first being explicitly granted permission of the property owner.
