\u00c0 984 m\u00e8tres, le lac de Blanchemer occupe un cirque glaciaire creus\u00e9 dans la vall\u00e9e de la Vologne. Il doit son nom \u00e0 l’hiver : quand la neige se refl\u00e8te dans l’eau, le lac prend l’apparence d’une mer blanche \u2014 \u00ab Biantchemer \u00bb en lorrain. Aujourd’hui encore, une centrale hydro\u00e9lectrique install\u00e9e en 1958 utilise ses eaux.<\/p>\n
Le tour du lac est une boucle de 1,66 km, d\u00e9nivel\u00e9 quasi nul, que l’on parcourt en une vingtaine de minutes. Elle est praticable avec une poussette \u00e0 grandes roues, m\u00eame si l’acc\u00e8s direct \u00e0 la rive reste difficile. Des tables de pique-nique sont install\u00e9es sur place, et le parking se trouve au bord m\u00eame du lac.<\/p>\n
Ce qui distingue Blanchemer des autres lacs vosgiens, c’est sa tourbi\u00e8re flottante \u2014 un radeau de sphaignes class\u00e9 ZNIEFF. Elle se voit bien depuis le sentier, mais elle est dangereuse d’acc\u00e8s : la surface para\u00eet solide et ne l’est pas. \u00c0 observer de loin, sans s’y aventurer.<\/p>\n
La baignade est interdite et l’eau est froide. En revanche, la p\u00eache est autoris\u00e9e : truite fario, perche, tanche, gardon, carpe. Le quota est de 6 truites par jour (taille minimale 23 cm), la p\u00eache en barque et de nuit est interdite, et la saison se ferme le 3e dimanche de septembre \u2014 \u00e0 v\u00e9rifier chaque ann\u00e9e aupr\u00e8s de l’AAPPMA La Bresse.<\/p>\n
En juillet-ao\u00fbt, le site est tr\u00e8s fr\u00e9quent\u00e9. Pour profiter du calme, mieux vaut venir t\u00f4t le matin en semaine, ou choisir le printemps et l’automne. La route d’acc\u00e8s est ferm\u00e9e en hiver : le lac reste atteignable \u00e0 pied ou en raquettes depuis la vall\u00e9e, mais l’approche est alors bien plus longue que le simple tour du lac. Les toilettes situ\u00e9es pr\u00e8s de la Cabane de Blanchemer \u00e9taient ferm\u00e9es en septembre 2025 \u2014 ne pas compter dessus sans v\u00e9rifier sur place.<\/p>","protected":false},"featured_media":5514,"template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"class_list":["post-5280","decouverte-vosges","type-decouverte-vosges","status-publish","has-post-thumbnail","hentry"],"_links":{"self":[{"href":"https:\/\/vosges-grandeur-nature.fr\/de\/wp-json\/wp\/v2\/decouverte-vosges\/5280","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vosges-grandeur-nature.fr\/de\/wp-json\/wp\/v2\/decouverte-vosges"}],"about":[{"href":"https:\/\/vosges-grandeur-nature.fr\/de\/wp-json\/wp\/v2\/types\/decouverte-vosges"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vosges-grandeur-nature.fr\/de\/wp-json\/wp\/v2\/media\/5514"}],"wp:attachment":[{"href":"https:\/\/vosges-grandeur-nature.fr\/de\/wp-json\/wp\/v2\/media?parent=5280"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
