Open directions in Google Maps or Apple Maps, or view the map on the Hidden Falls listing. Navigation apps sometimes route onto seasonal forest roads, so check road status if you are heading into the mountains.

Most of Alaska's named falls lie on public land managed by the Tongass and Chugach national forests, the National Park Service, state parks such as Chugach State Park, or the Bureau of Land Management, with some on Native corporation land where permission may be needed. Only a minority are on the road system; elsewhere, access depends on ferries, floatplanes or boats, and weather delays are routine. Bears are present across the state, so carrying bear spray and making noise on brushy trails is standard practice. Glacial meltwater is dangerously cold and silty, which hides depth and footing, and rivers rise quickly on warm afternoons. Near glaciers, ice calving and rockfall make approaching the base of a fall unwise. Rain gear and layers are essential even in July.

What to bring

This checklist is tailored to Hidden Falls based on what visitors report and the conditions typical of Alaska. For the complete list, see our waterfall hike packing guide.

• Offline map and coordinates. Save 57.21639, -134.87417 and download offline maps; cell service is often weak near waterfalls.
• Shoes with real grip. Rock near falling water stays wet and slick even in dry weather.
• Water and a snack. More than you think you need, even for a short walk.
• A light rain layer. Spray from the falls and quick-moving showers can soak you.
• Warm layers. Northern and mountain weather changes quickly; spring and fall mornings can be near freezing.
• Headlamp. In case your visit runs later than planned; check sunset time in the conditions panel above.

How to prepare

Timing

Alaska's waterfall season is short and runs roughly from late May into September. Snowmelt drives the strongest flows from late May through June in Southcentral and the Interior, while glacier-fed streams keep running hard through July and August as summer heat melts ice. In Southeast Alaska, rain matters as much as melt: the wettest stretch typically arrives in autumn, so September and October can produce surging falls along with low cloud and short days. Brooks Falls draws visitors in July, when sockeye runs peak, and again in September. Winter brings deep snow, avalanche danger on steep approaches and many frozen falls, though some roadside cascades become ice climbing objectives. Cruise-ship days concentrate crowds at Juneau and Skagway trailheads in midsummer. With 1 reviews, it sees fewer visitors than the region's headline falls, so you may have it to yourself on a weekday.

Safety

Stay behind railings and off wet rock, never climb on the falls, and keep children within arm's reach near the water. Check the weather panel above for flood or storm alerts before you set out; water levels can rise fast after upstream rain. Our waterfall safety guide covers the most common hazards.

Respect the place

Pack out everything you bring, stay on established paths to limit erosion, and leave rocks and plants where they are. See Leave No Trace at waterfalls.

History of the area

According to the U.S. Geological Survey's naming record: "Descriptive name given in 1923 byU.S. Forest Service (USFS)""so called because they are not seen until the upper end of the small lagoon at the head of Kasnyku Bay is reached."""

The federal gazetteer describes it this way: between Hidden Falls Lake and Kasnyku Bay, on NE coast of Baranof I.,

Hidden Falls was entered in the Geographic Names Information System on January 1, 2000, and it appears on the USGS Sitka A-3 NW 7.5-minute topographic map.

The U.S. Board on Geographic Names made a formal decision on its name on January 1, 1923.

Its neighbors on the map tell the story of the surrounding land: Hidden Falls Lake (lake, 0.7 mi) and Graystone Cliff (cliff, 1.7 mi).

Southeast Alaska and the Inside Passage. The Panhandle holds the largest share of Alaska's named falls. Temperate rainforest of spruce and hemlock covers steep slopes that drop directly to saltwater channels, and creeks fed by rain, snowfields and glaciers pour off them in long white ribbons. Juneau is the hub: Nugget Falls tumbles beside the Mendenhall Glacier at the end of a popular walk, while Ebner Falls sits above the Last Chance Basin just outside town, close to the city's old mining country. Skagway's Reid Falls is reached on a forest trail at the edge of town, and the Pitchfork Falls area above Goat Lake shows how far some of these streams drop. Many other falls here are seen only from boats and ferries.
