This spectacular day hike in the idyllic Lechquellen Mountains is one of our newest additions to Best Day Hikes in Austria. 

We loved this trail because of the pristine scenery (no ugly ski infrastructure), the awe-inducing alpine views of the Lechquellen and Verwall groups, and the terrain variation. It’s never boring – not for a single moment!

This point-to-point hike in Lech am Arlberg, Vorarlberg, requires the use of bus transit. Starting in Lech am Arlberg, take Bus 7 to Lake Formarinsee (30 minutes).

From Formarinsee, hike 11.3 km across the Steinernes Meer (“Stone Sea”) and over the Gehrengrat ridge, before descending to Lake Spullersee. From Spullersee, hop on Bus 6 back to Lech am Arlberg.

Formarinsee – Spullersee Hiking Map

How Difficult is the Hike from Formarinsee to Spullersee?

In dry conditions, this hike is moderate to difficult, depending on your alpine hiking experience. In wet conditions, this hike is very slippery and a bit treacherous due to the loamy terrain.

Specifically, there are two parts of this trail that we’d deem “moderately difficult:” crossing the karst Steinernes Meer and the initial descent from Gehrengrat.

Steinernes Meer. To hike across the Steinernes Meer, you need to have very good balance and surefootedness, because the terrain is very uneven. You must skillfully navigate slabs of karst pavement.

Gehrengrat. As you descend from Gehrengrat ridge in the direction of Lake Spullersee, the trail is washed out and unstable in some places. Hiking poles are extremely helpful in stabilizing your descent. We saw a lot of people struggling.

How to Get to Formarinsee Lake

Purchase a Lech Card

If you’re spending more than one day in Lech am Arlberg, it makes sense to invest in a Lech Card.

It’ll save you a lot of money in transit costs (bus, gondola, chairlift, cable car, etc…) and make your overall transit experience a whole lot smoother. Pricing Lech Card.

You can purchase Lech Cards at the tourist office in Lech am Arlberg, or in your hotel. 

If you don’t have a Lechcard, it costs 20 EUR (total) to travel from Lech to Formarinsee and back to Lech from Spullersee.

Take Bus 7 from Lech am Arlberg to Formarinsee

Bus Stop | Lech Rüfiplatz, next to the fountain and the wooden-covered “Tannbergbrücke” bridge | Google Maps

Transit Times | You’ll find the current timetable (local bus) at the bus stop. Usually, there are 8 departures during the day.

Duration | 30 Minutes

From Lech, the bus heads to Zugertal Valley, passing Zug, Spullerswald Forest, Gasthaus Älpele, and Tannlageralpe.

The road runs parallel to Lech River, so you’ll see the Lechweg (Lech River Trail, 1st stage) during the ride.

Drive to Formarinsee

We do not recommend driving to Lake Formarinsee during the official summer season.

However, if you’re arriving in Lech before/after the summer buses are operating, you can drive to Formarinsee. There is a 20 EUR toll fee.

When buses are operating, it’s also possible to drive to the lake before 8:00 am or after 4:30 pm.

Lake Formarinsee to Lake Spullersee Trail Description

Formarinsee to Freiburger Hütte (35 – 45 minutes)

From the bus drop-off point, head down the gravel track towards Formarinsee and follow the road to Freiburger Hütte (1918 m).

You can also hike the narrow trail on the east side of the lake, which is more scenic.

As you near Freiburger Hütte, you’ll start to see Rote Wand (“Red Wall”, 2704 m), one of the most beloved mountains in the Lechquellen Gebirge. 

Freiburger Hütte to Steinernes Meer (1 hour)

Wrap around Freiburger Hütte and follow signs to Steinernes Meer (signed 1:15 hours) and Spullersee (signed 4:15 hours). 

You’ll gradually ascend on an earthy track up a verdant slope.

In July, the trail is awash with splashes of pale-pink Maiden’s Tears, purple Alpine calamint and Wood Cranesbill, yellow kidney vetch, and Mountain Arnica. 

After hiking uphill for about 1.3 km, you’ll cross a pasture fence, and the rounded Formaletsch mountain comes into focus.

The trail levels out and continues horizontally along the south slope of Formaletsch. 

Here, you’ll see the crystalline Verwall mountain range straight ahead. 

Your hike will likely be enlivened by the sound of bells, as you’ll be traversing alpine pastures dotted with grazing cows and frolicking calves. 

To learn more about alpine pasture safety, read our guide to Visiting the Alps in Summer.

The easy path around Formaletsch delivers you to the Steinernes Meer, a karst landscape that is aptly called “Stone Sea.”

Steinernes Meer to Gehrengrat (1:30 hours)

Following the red-painted waymarks, slowly cross the heather-grey Steinernes Meer (about 30 – 35  minutes).

Given the unevenness of the terrain, this part can get a bit exhausting, because each step requires concentration. Visually and geologically, however, this is a very exciting part of the trail.

When you reach the Steinernes Meer trail intersection, the hard part is over. Continue straight in the direction of Gehrengrat and Spullersee (signed 3 hours).

The path is level and you’ll cross a meadow, before beginning the 280 meter ascent to Gehrengrat ridge.

The ascent has some steep sections, but it’s mostly quite gentle because of the loamy terrain.

As mentioned earlier, if the conditions are “wet,” then this will be slippery and more difficult. The ascent concludes with a series of switchbacks.

As you glance back, the views of Rote Wand and the Lechquellen Mountains make you wish you were hiking in the opposite direction.

Don’t worry, your descent will be accompanied by equally marvelous vistas on the other side. 

When you reach the top of Gehrengrat, you’ll see the limestone Rätikon and the crystalline Silvretta ranges, bordering Switzerland.

In the opposite direction, you’ll see Spullersee flanked by the dramatic Rohnspitze, Goppelsptize, and Wasenspitze.

Gehrengrat to Dalaaser Schütz (1 hour)

Following the ridge, descend in the direction of Spullersee. I was saying “wow” with every step. In some places, the trail is washed out and crumbling, which can be extremely problematic if you don’t have hiking poles or adequate footwear.

We recommend grade B/C high-cut hiking books like the women’s Hanwag Tatra II GTX / Meindl Schuhe Island Lady or the men’s Hanwag Tatra II GTX.

After navigating this steep descent, the trail levels out and you’ll cross the Glongbach stream, before gently descending across grassy meadows to the high valley of Dalaaser Schütz.

Dalaaser Schütz to Spullersee (40 minutes)

At the Dalaaser Schütz trail intersection, continue heading down along the wide track. Shortly thereafter, you’ll turn right, leaving the wide track, and follow the trail (there’s a waymark). 

The trail continues to descend gently and you’ll glide right to Spullersee.

Shortly before reaching the lake, you’ll cross a meadow blooming with purple Gentian (Gentiana purpurea).

At the lake, head left and walk 10 minutes to the bus stop.

You’ll find books in your room, by the pool, in the lobby, and in the hotel library. The hotel also holds literature events throughout the year as well as rotating exhibitions.

During our visit, there was an inclusive “Alles Familie” (All Families) children’s book exhibit, showcasing all types of families. 

Childcare is provided on most days for at least several hours. And, there are also playrooms for kids. 

Our favorite thing about Hotel Sonnenburg was our room. We just melted into the bed. The comforters are deluxe and the rooms are designed intentionally, exhibiting functional sophistication.

There’s space for everything and you really feel like you’re on vacation.

One last thing – breakfast is lavish. It’s like an ancient Roman banquet. It does not end. If we had to rank Austrian hotels based on breakfast, Hotel Sonnenburg would place number one.
