The printed Grand County plat book and the online parcel map answer the same question, who owns the land near Winter Park, in different ways. We'll cover what's in one, where Grand County copies turn up, and how the county's free map fills the gaps.
What a Grand County plat book is
Think of the Grand County plat book as a bound, printed version of ownership: township pages, owner names on each tract, and road maps for places like Winter Park. Don't confuse it with a subdivision plat on file for lots in Winter Park; that recorded plat is a legal document, while the atlas is a reference.
The county map you'll pair it with
For land around Granby, open the Grand County ArcGIS parcel map (an Esri ArcGIS web map); it is the map Grand County itself publishes. Use the search box for an address in Winter Park or a parcel number, or simply zoom in and click a tract around Granby. For a backup route to the map covering Granby, our Grand County directory entry keeps the link current.
Finding a printed Grand County plat book
Private publishers have printed plat books for many rural counties, but editions for Grand County come and go; check at the courthouse, the extension office or a farm supply store in Kremmling. An old atlas can help trace when a tract around Winter Park split off from a larger farm.
Reading a Grand County atlas page
Many atlases add rural residence listings and road maps, handy on back roads near Parshall. Acreage printed in a county atlas is approximate; the deed and a fresh survey decide the real figure for a tract around Winter Park. Genealogists in Colorado often pair an old Grand County atlas with deed records to follow a farm through the generations.
Old atlases and family history in Grand County

The Grand County economy in brief
Grand County's 2022 business count was 933 establishments, with construction, accommodation and food services, and real estate and rental and leasing the largest groups. Mining (except oil and gas) and beverage and tobacco manufacturing make up an above-average share of Grand County businesses, a clue to how land around Hot Sulphur Springs gets used.
Towns and land across Grand County
Town lots cluster around Hot Sulphur Springs, the county seat, and Fraser, Granby, Grand Lake, and Kremmling. Unincorporated communities in the county, including Parshall, Tabernash, and Radium, display up as small groups of parcels along the roads. Roughly 1,846 square miles of land and about 15,935 residents (2023 estimate) make up Grand County. Beyond the town lots in Grand Lake, expect big rural parcels across the county. Landforms such as the Rocky Mountain National Park shape where roads and homesites fall in Grand County. Grand County was organized in 1874, so deeds for older farms near Granby can run back a long way.
Tracts that cross the Grand County line
Grand County borders Boulder County, Clear Creek County, Eagle County, Gilpin County, and Jackson County, and each keeps its own parcel map and records. Our Colorado page links each map neighboring Grand County.
Current owners without a printed book
Between editions, use the Grand County ArcGIS parcel map; it lists owners, acreage and parcel IDs for land near Winter Park at no cost. Print a screenshot of the tracts around Kremmling if you want a paper copy in the truck.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
