INTRO

Grosskirchheim is a 9.9-mile, 4,540-foot climb averaging 8.6% out of the village of Dollach, in Austria's Kärnten region, just down the valley from Heiligenblut and the base of the famous Grossglockner Hochalpenstrasse. Locally the road is known as the climb to the Grosssee, a small reservoir tucked into the Zirknitztal side valley at 2,378 meters.

What makes this climb distinctive is how quiet it is. A gate at roughly mile 5 blocks the upper road to all but service vehicles, hikers, and cyclists, so the back half of the climb is essentially car-free - a genuine alternative for anyone who wants Grossglockner-caliber scenery without the tour-bus and motorcycle traffic on the main Hochalpenstrasse a few miles away. Expect double-digit pitches for most of the climb above the gate, including a steep stretch around 16-18% just past a small bridge, with marmots, high pastureland, and views back down the valley the whole way up.

The road belongs to the hydroelectric company that built the small dam at the Grosssee, and it dead-ends at the reservoir's gates - there's no through route, so plan on descending the way you came. Pavement is generally good but has a rough patch or two partway up; nothing has been reported closed or under construction as of mid-2026.

This climb averages 8.6% over 9.9 miles, gaining 4,540 feet to a summit at 7,810 feet. The steepest sustained section is a roughly 100-meter stretch around 16-18%, encountered just past a small bridge shortly after the gate at mile 5. Expect low double-digit pitches routinely from the gate to the top, broken up by only a few flatter stretches to recover on.

Roadway: Paved the entire way. The first stretch out of Dollach is in good shape, there's a rougher patch of pavement roughly a third of the way up, and conditions improve again above that. The steepest section - about 100 meters around 16-18% - comes just past a small bridge shortly after the gate. Expect metal drainage grates and a few water-filled ruts on the upper switchbacks, which are more of a nuisance on the descent than the climb.

Traffic: Light from Dollach to the gate around mile 5, then effectively car-free above it - the upper road belongs to the hydroelectric company that built the small dam at the Grosssee and is closed to public vehicles, open only to service traffic, hikers, and cyclists.

Parking: Dollach is a small village bordering Heiligenblut with no dedicated climb parking lot - park along the road near the start, at the "T" intersection of Mitten Strabe and Dollach Strabe. For a nearby alternative with a similar quiet, gated upper section, the Hochwurtenspeicher climb starts across the valley in Flattach.

Bring your lowest available gearing - with pitches into the mid-to-high teens above the gate, a 34x34 or lighter is a reasonable minimum, and this is a genuinely hard enough climb that a slightly easier gear than you think you need is the right call. There are no shops, cafes, or water stops once you leave Dollach, so carry all the food and water you'll need for the full out-and-back. A light isn't required (there's no tunnel on this route, unlike some of its neighbors), but a rear blinker is worth having given the mix of shaded forest sections and the occasional service vehicle on the lower road.

Dollach sits just down the valley from Heiligenblut, so it's an easy add-on if you're already staying in the area to ride the Grossglockner Hochalpenstrasse. This climb makes a nice quieter counterpart to that one - same general area, none of the tour-bus traffic. If you want a second big effort nearby, Hochwurtenspeicher climbs a similarly punishing, mostly car-free road out of Flattach on the other side of the valley - riders who've done both describe this one's descent as noticeably smoother. Check our Routes in the Area tool from this climb's page to see what else is within reach before you commit to a base for your trip. Bring layers - even on a warm day in the valley, the top of this climb sits above 2,300 meters and can be considerably cooler and windier than the start.
