Overview
Pillar Falls is a waterfall near Twin Falls, Idaho. Several basalt pillars divide the Snake River into multiple channels, through which the river drops about 20 feet (6 m).
Practical Info
Suggested Duration2-4 hours
Best TimeThe late summer months from July to September are the prime visiting window, when reduced river flows expose the bizarre, massive basalt rock pillars and slot canyons splitting the Snake River channel. Midday from 11:00 AM to 3:00 PM is ideal, allowing the overhead sun to illuminate the shallow green pools and rushing rapids woven between the rocks.
Getting ThereThis geological wonder is completely inaccessible by standard roads or cars. The premier method to reach it is via a water approach: park your vehicle at Centennial Waterfront Park's free riverfront lots, launch a rented kayak or paddleboard, and paddle upstream (eastward) under the Perrine Bridge for roughly 1.5 miles to make landfall on the rock islands.
Travel Tips
- Parking is structurally banned at the immediate Pillar Falls trailhead on private easement access; you must legally park at the designated Pole Line Road public lot and hike down to avoid trespass towing.
- Powerful underwater basalt undercurrents and hydraulic traps make swimming fatal at Pillar Falls; state water safety laws mandate that all kayakers approaching the rhyolite pillars must wear active Type III PFDs.
- The canyon descent trail to the falls scales an intense 25-percent grade over loose scree and slick mud; technical hiking boots with deep lugs are required, and late-afternoon descents into this radio blindspot are prohibited.
Reviews
Positive
- Masterful nature work! Massive basalt rock pillars erupt from the mid-river, slicing currents into winding, roaring micro-cascades.
- Pure, rugged backcountry adventure! Reached only by kayaking upstream from Centennial Park or hiking cliff paths, making it highly rewarding.
- During low-water autumns, you can step directly onto exposed volcanic flats to explore intricate tide-pools and slots with amazing fun.
- Zero fees, zero fences, zero commercial traps; preserves the purest, jaw-dropping river canyon wonders of thousands of years.
Heads up
- Abysmal accessibility; for non-boaters, the sole land trail is a terribly steep, gravelly 'goat path' descending the cliff, killing stamina.
- High safety risk; the basalt riverbed rocks are constantly washed by water and coated in slick algae, causing extreme slip or fall hazards.
- Total zero-amenity absolute wilderness; zero toilets, zero bins, zero signs, and 100% dead cellular signal coverage throughout the base.
- During spring high-water or sudden upstream dam releases, the rocks get completely drowned under violent rapids, making visits fatal.
