The road to Heimischgarten isn’t an easy one

Heimischgarten is a high mountain pass at an elevation of 2.770m (9,087ft) above the sea level, located in the district of Visp in the canton of Valais in Switzerland. It's one of the highest roads of Europe.

The road to the summit is extreme. 4x4 with high clearance only. It’s very narrow, with deep washouts and loose gravel. It's one of the highest roads of the country. The maximum gradients reach up to 20%. The road is usually impassable from October to June (weather permitting). Great trail for experienced wheelers. Avoid driving in this area if unpaved mountain roads aren't your strong point. 4x4 vehicle required. Stay away if you're scared of heights. Expect a trail pretty steep. Thunderstorm activity can quickly change unpaved roads to four-wheel-drive condition or make them impassable. The track starts at the small town of Saas Balen at the bridge over the Vispa.
