For inexperienced hikers, the smartphone is a multi-purpose device: a flashlight, emergency beacon and GPS, all in one device. Experts say he can advise hikers to have full reliance on their phones when going into the woods and is potentially life-threatening.

Apps and maps online maps have left hikers stranded on both sides of the Atlantic.

Mountaineers in Scotland are warning visitors that Google Maps could lead them to “potentially fatal” roads that will force them to trek on rocks and rocky, steep terrain.

A joint statement from the climbing organization, Mountaineering Scotland and the natural conservation charity John Muer Trust on Thursday said a number of visitors recently relied on Google Maps to reach the summit of Mount Ben Nevis, a 4,500-foot mountain. Areas in Britain.

About 70 miles northwest of Glasgow, Ben Nevis, a popular but dangerous climb in the Scottish Highlands, is the highest peak in Britain.

If hikers follow Google’s instructions in the parking lot near the summit, the map points them straight to the top of the mountain. Mountaineer Scotland’s mountain safety adviser, Heather Morning, said in a statement that even experienced climbers would struggle that way.

“In good visibility it would be challenging,” Ms. Said in the morning. “Add in less cloud and rain and the suggested Google line is potentially fatal.”

The trouble is, while smartphones have simplified many activities from car oiling to taking orders, devices have complicated things for some hikers who don’t realize they will need more than their phones.

Mountaineer Scotland reports that many people in the country have been injured following recent hiking routes found online. Ben Nevis has been the site of several deaths in recent years, including a 24-year-old woman last month and three men in 2019.

The mountaineers’ warning came as hikers flocked outside and on the roads during the coronavirus epidemic. While hiking is an attempt at a safe, social distance, injuries have become an issue as more people collide on the roads.

Ben Nevis is not the only mountain where hikers are in trouble. In New Hampshire, mountain rescuers said they rescued many people who were not equipped for their hike.

Hikers from the White Mountains hire the New Hampshire Fish and Game Department at least once a week in the summer, according to the S.G.T. Alex Lopashansky, Department of Defense Officer.

“They try to follow the trial on their phone, which takes them to the woods, and they get so lost in themselves.”

These hikers can’t tell where they are because their screens are much smaller than paper maps, Sergeant Lopashansky said. If officers can’t bring them back to a trial over the phone, it could take rescuers several hours to find them.

More complex factors include devices wandering into remote areas without cell service or power outages, rendering them useless for calling for help.

Rescue agencies join the operation if hikers are at risk. Rick Wilcox, a member of the Mountain Rescue Service in New Hampshire, said many of the people they rescued did not have maps or compasses.

“People believe that magical cellphones are what they need and they go,‘ Let me google check, ’” Mr. “And that’s what’s wrong there,” Wilcox said.

Wesley Trimble of the American Hiking Society said they were concerned about people using apps to follow routes that were not recognized by experts.

“A lot of information on the Internet is a crowded source, so no input from land administrators or parks or trail organizations is required.”

In Scotland, authorities recommend that visitors bring Ben Nevis a paper map and compass, even on novice roads.

For those willing to venture out into the icy terrain of the mountains, steep cliffs and poor visibility, there is an eight-hour round trip from the visitor center to the summit. But if the hikers follow Google Maps at its proposed initial stage, their journey will be even more treacherous.

The John Muer Trust posted signs in the area to direct inexperienced climbers to the visitor center, but people often ignore these postings, a charity spokesman said.

A Google spokesman said in a statement that the map’s dotted line from the parking lot to the summit, to indicate the distance from the top, was not a walkable trail.

“Our driving directions currently lead people in the direction of the Nevis Gorge Trailhead parking lot – near the summit – with prominent signs indicating that this trail is extremely dangerous,” the statement said.

Regardless, the company said users will now be directed to the mountain visitor center instead of the parking lot. A Google spokesman said the company was reviewing its other routes near Ben Nevis.

Organizations can update mapping information using Google’s Geo Data Upload tool, the company said. Users can report issues directly to Google.
