Much of its mountainous area is reserved as [[White Mountain National Forest|national forest]], wilderness, state parks and other public areas; these encompass most of the northern portion of the [[White Mountains (New Hampshire)|White Mountains]], including all the named [[Summit (topography)|summits]] of the [[Presidential Range]] (though one, [[Mount Webster|Mt. Webster]], lies about {{convert|200|ft|m}} from the [[Border|county line]]). [[Mount Washington (New Hampshire)|Mt. Washington]]'s peak is the highest in the Northeast. The {{convert|162|mi|adj=on}} [[Cohos Trail]] runs the length of the county.<ref>[https://www.bostonglobe.com/metro/2011/10/15/hiker-completes-creation-mile-trail/ "Hiker completes creation of 162-mile trail"]{{Dead link|date=July 2019 |bot=InternetArchiveBot |fix-attempted=yes }}, Billy Baker, ''Boston Globe'', October 16, 2011</ref>

The principal [[New Hampshire Highway System|state highways]] in Coös County are [[New Hampshire Route 16]], which runs mostly parallel to the Maine state line and through the city of [[Berlin, New Hampshire|Berlin]], and [[New Hampshire Route 26]], which traverses the [[Great North Woods Region (New Hampshire)|Great North Woods]] from [[Vermont Route 102]] southeast to [[Maine Route 26]] towards [[Portland, Maine|Portland]]. The two major [[United States Numbered Highways|U.S. Highways]] are [[U.S. Route 2]], which roughly bisects the county from [[Lancaster, New Hampshire|Lancaster]] to the [[Oxford County, Maine|Oxford County]] line, and [[U.S. Route 3]], which runs from [[Carroll, New Hampshire|Carroll]] in the south to the [[Pittsburg–Chartierville Border Crossing]], where it continues as [[Quebec Route 257]].

Coös County is the least populated of all New Hampshire counties, and the only one with significant amounts of [[unincorporated land]]; over half of the municipal-like entities are unincorporated townships, gores, or grants, a rarity in New Hampshire, where nearly all of the land is incorporated as [[New England town|towns]] or [[city|cities]]. The population of these unincorporated territories is minuscule; collectively they account for less than 1% of the population of the county, with only three ([[Wentworth Location, New Hampshire|Wentworth Location]], [[Millsfield, New Hampshire|Millsfield]], and [[Cambridge, New Hampshire|Cambridge]]) reporting populations in the double digits for recent censuses. Approximately 1/3 of the population lives in [[Berlin, New Hampshire|Berlin]], the only city, most populous municipality, and economic hub. [[Lancaster, New Hampshire|Lancaster]] serves as the [[county seat]].
