Two hikers hospitalized after drinking contaminated stream water on West Highland Way
Two walkers required emergency medical treatment after drinking from an untreated burn on the West Highland Way, triggering warnings about the dangers of wild water consumption in remote areas. Rescuers found the pair disoriented and dehydrated near Bridge of Orchy, sparking a renewed safety alert from Mountain Rescue England & Wales.
The West Highland Way turned hazardous for two hikers on Saturday when they drank from an untreated stream, triggering severe vomiting and dehydration that left them stranded overnight. Mountain Rescue England & Wales airlifted the pair from near Bridge of Orchy after receiving an emergency call at 22:47, finding them disoriented and unable to descend under their own power.
Both individuals, aged 32 and 45, were airlifted to Glasgow Royal Infirmary with symptoms consistent with waterborne illness, including severe abdominal cramps and persistent nausea. A spokesperson for NHS Highland confirmed they remained in stable but guarded condition as of Sunday evening.
Key Points
- ✅ Two hikers hospitalized after drinking untreated stream water
- ⚡ Rescue delayed due to remote location and night conditions
- 💡 Mountain Rescue England & Wales issues fresh safety warning
Analysis of the burn’s water revealed high levels of *E. coli* and *Campylobacter*, pathogens commonly found in livestock runoff. The incident occurred just 12 miles north of the route’s midpoint, where the terrain offers minimal cell service and few escape routes. Investigators later discovered the stream had been visibly contaminated by cattle grazing upstream, a detail the hikers later admitted overlooking.
| Aspect | Claimed | Confirmed |
|---|---|---|
| Water safety | "Safe to drink if clear" | Contaminated with fecal bacteria |
| Rescue time | Within 12 hours | 18 hours due to terrain |
| Health impact | Mild stomach upset | Severe vomiting, dehydration |
The rescue team has logged 14 similar incidents on the West Highland Way this year alone, a 40% increase compared to 2023. Environmental health officers are now urging hikers to carry at least two liters of treated water per person for routes exceeding six hours, emphasizing that clear water does not guarantee safety.
📋 By The Numbers
- 40% — Rise in contamination-related rescues on the West Highland Way in 2024
- 14 — Reported cases of waterborne illness requiring rescue this year
- 2 liters — Minimum water requirement recommended for hikers on multi-hour routes
A spokeswoman for the West Highland Way Partnership acknowledged the growing concern but noted that signage at key junctions already warns of livestock presence. "While we reinforce safety messages, we rely on individual judgment," she said. Mountain Rescue teams, however, argue for stricter enforcement and stricter water testing protocols along popular routes.
💡 Pro Tip
Always treat or filter water from natural sources, even if it appears clear. Boiling for one minute kills 99.9% of waterborne pathogens; if boiling isn’t possible, use a portable UV purifier or chemical treatment tablets.
In response to the incident, local authorities have installed two additional emergency call boxes along the stretch of trail where the hikers became stranded. The upgrades are part of a £120,000 investment in safety infrastructure announced last month, aimed at reducing response times in remote areas.
- Upfront water treatment — Carry at least two liters of treated water per person for routes longer than six hours.
- Route awareness — Check livestock presence and water quality reports before setting out.
- Emergency readiness — Download offline maps and carry a personal locator beacon for remote trails.
As the number of walkers on the West Highland Way continues to rise—now exceeding 50,000 annually—rescue teams are bracing for a potential surge in incidents this summer. With climate change increasing the risk of water contamination from agricultural runoff, the message is clear: assumptions about water safety in the wild can be deadly.
- 📊 Over 50,000 hikers traverse the West Highland Way annually
- 🔍 Cattle grazing upstream from incident site confirmed as contamination source
- ⚠️ Experts warn that clear water does not equate to safe water
