St. Mary Falls is the east side's essential short hike — a walk of a mile or so down through the 2015 burn to a bridge where the St. Mary River detonates through a rock chute in stacked turquoise tiers. The color is the shock: glacial sediment turns the water an unreal blue-green that photographs like a rendering error. The falls sit about 35 feet tall across multiple drops, the wooden footbridge crosses directly below them, and the spray is the east side's best air conditioning on a hot afternoon. Most hikers continue the extra stretch to Virginia Falls — taller, broader, and the perfect second act.

Getting there & parking

How To Get There
On the St. Mary Falls trail network off Going-to-the-Sun Road near mile 39 - start from the St. Mary Falls trailhead/shuttle stop, Sunrift Gorge, or Sun Point; roughly one to two miles each way depending on the start. The footbridge crosses directly below the falls.
Road Type
Paved road access to dirt trail - the walk descends through the 2015 Reynolds Creek burn.
Parking Availability
Trailhead lots fill by mid-morning in summer - the shuttle stop makes this the east side's most shuttle-friendly hike.

When to go

Best Time To Visit
Morning for light in the chute and cooler burn-zone walking — the 2015 fire left the descent shadeless. Early summer for maximum thunder; the color holds all season.
Best Visit Times
Mornings - cooler burn-zone walking, softer light on the water, thinner crowds.
Seasonal Access
Reachable whenever the east-side road is open; flow peaks early summer, the turquoise holds all season.

What you will experience

Attraction Type
Turquoise multi-tier falls
Main Features
About 35 feet of stacked turquoise tiers, footbridge directly below the drops, glacial-sediment blue-green water, Virginia Falls continuation, 2015 burn-zone descent
What Youll See
The St. Mary River compressing into a rock chute and dropping in stacked tiers of impossible blue-green - glacial rock flour scattering the light. Silver fire-killed snags frame the descent; the bridge puts you close enough for spray.
Unique Characteristics
The most vivid water color reachable on a short east-side walk - and half of the park's best two-for-one, with Virginia Falls under a mile beyond.
Photo Opportunities
Low from the footbridge with the tiers stacked above; soft morning light keeps the turquoise saturated; long exposures silk the chute.
Geological Formation Type
Chute falls over resistant Belt-rock ledges in the glacially carved St. Mary valley

Family Friendly Notes
One of the best kid hikes in the park — short, downhill in, a bridge over blue water at the payoff. Keep kids off the wet rocks; the current is violent, and the return climb earns the snacks.

Safety

Safety Considerations
Stay off the wet rock beside the chute - the current is violent and the polish is slick. The burn zone is shadeless; carry water. Grizzlies use the berry regrowth in late summer - carry spray, make noise.

Nearby

Nearby Attractions
Virginia Falls under a mile upstream - taller, broader, many hikers' favorite. Sunrift Gorge and Baring Falls on the connecting trail. Sun Point at the network's east end.
Trailheads Here
The falls sit mid-network: trails connect the St. Mary Falls trailhead, Sunrift Gorge, Sun Point, Baring Falls, and Virginia Falls into flexible out-and-backs.

Planning advice

Insider Tips
  • Shoot from the bridge, low, with the tiers stacked above — the turquoise reads best in soft light.
  • The shuttle solves the parking problem: ride to the St. Mary Falls stop and walk down one-way options.
  • The dead snags from the Reynolds Creek Fire have become part of the look — silver trunks against blue water; the regrowth understory is head-high and full of berries by late summer (hence the bears).
Tips Advice
  • Multiple starting points reach the falls: the St. Mary Falls trailhead and shuttle stop, Sunrift Gorge, or Sun Point — roughly one to two miles each way depending on where you start.
  • Continue to Virginia Falls: under a mile further, and most people's favorite of the two.
  • The burn zone is exposed — hats and water on hot days.
  • Grizzlies frequent the drainage; carry bear spray and make noise at the brushy creek crossings.

Location

Frequently asked questions

How long is the hike to St. Mary Falls?

Roughly one to two miles each way depending on the trailhead — the dedicated St. Mary Falls trailhead is shortest; Sunrift Gorge and Sun Point add distance. It's an easy-to-moderate descent going in, with the climb saved for the return.

Why is the water that color?

Fine glacial sediment suspended in the meltwater scatters light toward blue-green — the turquoise is real, unfiltered, and strongest in bright light.

Should I continue to Virginia Falls?

Yes — it's under a mile further, and its broad 50-foot veil is many hikers' favorite of the pair. The two falls make one natural out-and-back.

How tall is St. Mary Falls?

About 35 feet across stacked tiers — the power and the color, not the height, are the show. The footbridge crosses directly below the drops.

Is the trail through a burn area?

Yes — the 2015 Reynolds Creek Fire burned the descent. Expect open, shadeless walking among silver snags, with vigorous berry-brush regrowth that bears use in late summer: carry spray.
