The National Park Foundation's Trail Talk Blog offers readers a peek into the breadth and wonders of America's National Park system, with everything from recommended hikes to popular activities to educational opportunities. On the site, various authors post entries at least four times per week. Recent items have included a meditation on the importance of Martin Luther King, Jr. Day, a discussion of some hidden park gems, like the Great Sand Dunes National Park in southern Colorado and the backcountry in Utah's Canyonlands National Park, and an argument for how the national parks connect us to each other. Blog posts date back to 2008 and, since the majesty of the parks has changed little, readers will find excellent tips and tidbits in many of the thousands of items stored in the Trail Talk Archive.
