Lac Cornu and the Lacs Noirs, classified as \u2018\u2019intermediate\u2018\u2019, remain one of the wonders on offer to the bewildered observer. The route, which requires little effort, includes some steep sections and n\u00e9v\u00e9s without risk. However, there are no aerial or vertiginous passages on these well-marked paths.<\/p>\n<p>The route starts at the top of the Planpraz cable car, which eliminates much of the climb. However, the latter can be climbed by a path that brings no pleasure whatsoever.<\/p>\n<p>I promise you unforgettable memories in these sublime landscapes, where your eyes are constantly drawn to the most prestigious peaks within easy reach, and to the glaciers where, alas, we can only observe the effects of accelerating global warming.<\/p>\n<p><span class=\"cap\" ><script async=\"\" src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js\"><\/script><\/span><\/p>\n<p><ins class=\"adsbygoogle\" style=\"display: block;\" data-ad-client=\"ca-pub-3567350517589380\" data-ad-slot=\"5784331615\" data-ad-format=\"auto\"><\/ins><br \/>\n<script><br \/>\n(adsbygoogle = window.adsbygoogle || []).push({});<br \/>\n<\/script><\/p>\n<blockquote>\n<ul>\n<li><strong>Difficulty<\/strong>: Intermediate <img decoding=\"async\" class=\"alignnone size-full wp-image-710\" src=\"http:\/\/www.randos-montblanc.com\/images\/bouton\/hiking-icon-moyen.png\" alt=\"hiking-icon-moyen\"\/><\/li>\n<li><b>Altitude<\/b>: 2,276 m at the Lac Cornu, 2,540 m at the Lacs Noirs<\/li>\n<li><b>Ascent<\/b>: 1 hour 45 min to get to the Lac Cornu, 2 hours 30 min to get to the Lacs Noirs<\/li>\n<li><b>Descent<\/b>: 1 hour 30 min from the Lacs Noirs<\/li>\n<li><strong>Elevation Gain<\/strong>: 790 meters<\/li>\n<li><strong>Round-trip<\/strong>: 11.0 km<\/li>\n<li><strong>Map<\/strong>: <a href=\"http:\/\/www.randos-montblanc.com\/images\/ign\/ign-cornu.jpg\" onclick=\"return popitup(this.href, 500, 500);\" class=\"simple_popup_link \">&lt;b&gt;IGN 3630 OT&lt;\/b&gt;<\/a><\/li>\n<li><strong>Restrictions<\/strong> : Dogs (even on a leash) and gathering prohibited.
