Two walkers were rescued after falling severely ill while hiking Scotland's West Highland Way long-distance trail, according to rescue authorities.

The hikers became sick after drinking water from a burn, a Scottish term for a small stream or creek. Despite using water filters, both walkers developed severe illness that required emergency rescue.

The West Highland Way is a popular 96-mile hiking route that runs from Milngavie near Glasgow to Fort William in the Scottish Highlands. The trail attracts thousands of hikers annually who typically complete the route over several days.

Rescue teams responded to assist the ill walkers, though specific details about their condition or the exact location of the incident were not immediately available. The incident highlights ongoing concerns about water safety for hikers on remote trails, even when using filtration equipment.
