Formed by the Kapruner Ache river over thousands of years, the Sigmund Thun Gorge is a narrow, deep chasm in the Kaprun valley. A maintained wooden walkway (Stege) follows the rock walls, allowing visitors to walk directly above the glacial water. The gorge is 320m long and up to 30m deep. The route continues past the gorge to the clear Klammsee lake, which offers a circular walking path and views of the surrounding Hohe Tauern peaks.
St Nectan's Glen is an enchanting, atmospheric woodland valley deeply cut into the Cornish slate near Tintagel. This short, easy 1.9-mile (3km) circular walk follows the tumbling River Trevillet through ancient, moss-draped oak trees and ferns. The destination is a spectacular 60-foot waterfall that has punched a flawless circular hole directly through the rock basin, creating a deep pool below. The glen has been designated a Site of Special Scientific Interest (SSSI) due to its rare flora and is considered by many to be one of the most spiritual and magical places in the UK.
Head-to-Head Metric Analysis
HikeMetrics Hazard Scale — Explanation
The HikeMetrics Hazard Scale is a proprietary 5-point classification system that evaluates hiking routes across five dimensions: physical demand, technical complexity, altitude exposure, weather risk, and rescue accessibility.
Unlike generic star ratings, the Hazard Scale is calibrated against altitude profiles, elevation gain per day, and logistical isolation factors — making it the most precise route classification system available.
