Wimbachgries

Overview

This is the classic out-and-back up the Wimbach Valley to Wimbachgrieshütte—a long, steady walk through one of the Alps’ more unusual landscapes. Plan on roughly 10.5 miles total (about 16.9 km) with around 2,400 ft/730 m of gain and 6–6.5 hours moving time. Surfaces trend toward easy: a mix of asphalt, gravel, and forest paths with a consistent, never-terrifying incline.

Why it’s special

You’re hiking on the Wimbachgries, a massive debris plain built from brittle Ramsau dolomite that has weathered into gravel ("grus"). The actual bedrock valley floor lies far below—the gravel fill is described as reaching up to ~300 m deep in places. Above, bands and walls of Dachstein limestone frame the scene, with the Watzmann and Hochkalter groups providing the drama. The Wimbach stream often disappears beneath the gravel and reappears in shallow rivulets, adding to the valley’s stark, high-alpine feel below treeline.

Route, turn-by-turn

Start at the Wimbachbrücke car park and follow signs up the Wimbachweg. Shortly after the start, you can choose the boardwalk gorge of Wimbachklamm (seasonal, fee) or the parallel forest path; they rejoin soon after. Continue to Wimbachschloss—a natural rest spot—then keep following the obvious track into the wide gravel valley to reach Wimbachgrieshütte. Return the same way. Waymarks 411/421 lead up-valley past Wimbachschloss.

What to expect

The grade is steady and the footing mostly straightforward, but the distance adds up. The valley can feel austere and surprisingly open; look for Swiss mountain pine and low alpine shrubs dotting the rubble, and for the striking, layered rock architecture on the valley walls. Highlights include the optional Wimbachklamm near the start, Wimbachschloss mid-route, and the small beer-garden vibe at Wimbachgrieshütte when it’s operating.

Best time to hike

Late spring through early autumn is the sweet spot. The gorge is typically seasonal; if it’s closed, use the parallel path. The valley falls into shade earlier than surrounding peaks, so start early for the best light and a quieter ascent, and to avoid the common afternoon return rush. In any season, check local trail and hut status, weather, and daylight before committing.

Tips and logistics

• Water can be unreliable at the surface because the stream often runs underground—carry what you need and don’t count on refills unless you know the hut is open.
• It’s a protected area: stay on marked paths, leash dogs, pack out trash, and skip drones and fires.
• Don’t mix this valley hike up with the serious Watzmann ridge traverse that also ends at Wimbachgrieshütte; that alpine route involves exposed sections and, for many, a via ferrata set.

Is it for you?

If you like big scenery without technical moves, this one’s rewarding. The tradeoff: long stretches of gravel road feel and a fairly uniform grade. Short on time? Turn around at Wimbachschloss for a solid, shorter day and keep the full push to the hut for when you can savor it.
