Lake Formarinsee to Lake Spullersee Day Hike, Vorarlberg, Austria

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).

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

Lech am Arlberg, Austria
Lech am Arlberg

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)

Formarinsee, Lechquellen Mountains, Vorarlberg

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, Formarinsee, Vorarlberg

Freiburger Hütte to Steinernes Meer (1 hour)

Formaletsch, Formarinsee to Spullersee Trail

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.

Steinernes Meer, Lechquellen Mountains Day Hike, Vorarlberg

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)

Rote Wand, Lechquellen Mountains, Day Hike Lech am Arlberg

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.

Gehrengrat views, Lechquellen Mountains

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)

Gehrengrat, Day Hike in the Lechquellen Mountains

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)

Hike to Spullersee, Lechquellen, Austria

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.

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.

When to Visit Austria 

Summer and early Fall are our favorite seasons in Austria. 

Getting around Austria

Austria has an excellent public transit system. We’ve used it extensively to travel throughout the country. We highly recommend using transit if you’re visiting cities (Vienna, Salzburg, Innsbruck, Graz, etc…), and/or doing hut-to-hut hikes. 

Some areas like Mayrhofen, Schladming and Lech am Arlberg have wonderful seasonal transit systems in place (e.g. summer hiking buses). However, if you’re not visiting during the high season, bus frequencies are significantly reduced and it’s far easier to get around with your own vehicle. 

If you’re planning on visiting multiple destinations across  Austria, we recommend renting a car. 

Use these road trip itineraries for trip planning inspiration:

Car Rental 

We recommend using the car rental reservation platform to search for and book car rentals. This easy-to-use booking platform compares car rental deals from 500+ trusted providers, so that you can choose the best option for your trip.

If you’re driving into Austria from a neighboring country, don’t forget to purchase a vignette at/near the border.

  1. Does this hike make sense in opposite direction? So as to stay at Freibergerhutte at the evening.

    I wonder if it would be less spectacular

    • Definitely! The views are great in both directions. If you hike from Spullersee to Formarinsee, you’ll have continuous views of the Rote Wand during the second half of the hike.

  2. I completed this hike in August 2021 and it was spectacular!! The view from Gehrengrat is unbelievable. I opted to hike from Spullersee to Formarinsee and for me that was perfect for a few reasons –
    1. The ascent up to Gehrengrat from Spullersee is quite steep. My knees and vertigo were both glad to be going up rather than down this part. I couldn’t have done it without poles.
    2. I wanted to end at the hut for lunch (it was great!).
    3. The Lech summer guidebook recommended going from Spullersee to Formarinsee and I figured there would be more people going in that direction, which I preferred as a solo hiker.

    There isn’t any shade along the trail so bring plenty of water and sun protection. My last piece of advice is to start as early as possible. The earliest #6 bus from town was 9:16. I wouldn’t want to be climbing up Gehrengrat with traffic coming from the opposite direction because the trail is very narrow, so an early start will help you avoid that. Can’t recommend this trail enough!

    • So happy to hear that you enjoyed this hike in Vorarlberg.
      Thank you for sharing your experience with us.

  3. I’m going to be in the region from June 14th till June 16th
    the buss only starts on June 18th – any other ways to get to the lake?

    • Hi Amir,
      If the bus isn’t operating, usually you can drive to the lake. The toll is 20 EUR. But, it’s possible that the summer buses will be operating early June this year.
      Have a great time in Lech,
