Athmar Park is bordered by Alameda Avenue on the north, Mississippi Avenue on the south, Federal Boulevard on the west and the South Platte River on the east. Four Denver parks, Aspgren, Huston Lake, Vanderbilt Park, and Habitat Park exist within the boundaries of Athmar Park. The eastern half of the neighborhood is lower in elevation than the west, with a sharp rise above the river beginning near Pecos Street and continuing the gradual climb in elevation toward the southwest. In contrast to the older grid-type streets found in many neighborhoods, Athmar Park has some streets that have long, flowing curves.
One of Colorado's busiest driver's license offices is located in the neighborhood at 1865-C West Mississippi Avenue.
In the year 2000, the racial breakdown of Athmar Park was 29.52% White, 0.84% African American, 0.43% Native American, 3.15% Asian, and 65.21% Hispanic or Latino. More recently, with the publication of the 2010 United States Census, out of a total population of 8,898, small changes in race and ethnicity put the population at 63% white or Hispanic/Latino, with 73% of that number claiming Hispanic ethnicity and 27% listing non-Hispanic ethnicity. Residents with Asian (3.5%), American Native (2.1%), and African American (1.4%) fill out the remainder of the non-Hispanic population with 30% of that breakdown considering themselves "other" or "mixed".
Huston Lake Park is located in the center of the Athmar Park neighborhood between the streets of South Clay and South Vallejo, and the avenues of West Ohio and West Kentucky. With a variety of amenities including a bike and walking path, soccer and softball fields, tennis and basketball courts, and a children's play area, Huston Lake park provides many recreational resources for the local community. Named after one of the original land owners in the area, N.K. Huston, the park was originally the site of a patch of swampland called "Frenchie's Lake" which was used by early residents as a location to ice-skate in the winter and swim in the summer.
Located at the eastern edge of the residential areas of Athmar Park, Clifford Aspgren park was named after a resident who served in the Colorado House of Representatives.
Vanderbilt lake park contains both Habitat Park and Boy Scout Park and is part of the larger South Platte River Greenway. It contains a sports fields complex and is part of a series of parks connected by the South Platte River biking and walking trail system. Until 2011 Habitat Park was the home of the Denver Municipal Animal shelter, which moved to a site in the Valverde neighborhood to the north of Athmar Park.
Historically, Athmar Park was annexed incrementally by the City of Denver. In 1902, the eastern edge of Athmar Park was annexed, along with the town of Valverde, from Zuni to the South Platte River border. In 1932 the area west of Zuni was annexed by the City of Denver. The area west of the town of Valverde that had originally been in the hands of three different owners was auctioned and purchased by Thomas and John R. McCusker in 1946 and developed into the subdivision of Denver named "Athmar Park." According to urban legend, the name "Athmar" originated from the combination of the names of the developers' two wives—Athea and Mary.
In 1900, the northeast area of the neighborhood was "rural" and hosted celery farms and wheat fields. Several of the original brick country homes still exist on W. Nevada Place—dating from the late 1880s to the early 1900s. 1395 W. Nevada Place dates to the late 1880s, and 1597 W. Nevada Place dates to 1912.
The northwest portion of the neighborhood was originally called Mountainview. Many of the charming brick bungalows in this area of the neighborhood, each with a unique design, date from the 1920s and 1930s.
After World War II, there was a major housing boom during which a large number of the neighborhood "tract" homes were built.
Denver's first McDonald's restaurant was located in the neighborhood, at 2120 W. Alameda Avenue. The building is still there but hosts a different restaurant.
The neighborhood was affected by a destructive flood in June 1965 when the S. Platte River flooded outside its banks. Flood waters reached up to the basketball hoops at St. Rose of Lima Catholic Church school (1345 W. Dakota Ave.). Flood waters engulfed homes and businesses from the river all the way west into the 1400 blocks of the neighborhood. "The flooding along the South Platte River from Plum Creek to North Platte, Nebraska was the most destructive. The flood reached the South Platte River and the metropolitan areas of Denver by about 8 p.m. on June 16. The floodwaters spread to a half-mile or more in width. The peak discharge of the South Platte at Denver was 183 percent of the previous maximum during 67 years of record and historical information indicates that the 1965 discharge was the greatest since at least 1844. Many business, homes, industries, roads and highways were inundated. About 8,000 telephones were put out of service by the flood in the Denver area. More than half of these lines were not restored for several days.
The Denver metropolitan area suffered extensive damage. The flood zone represented 67 percent of the industrial area in the city. While the flood passed rather quickly on the night of June 16, the floodwaters were piled high with debris such as house trailers, lumber and large butane storage tanks. Many of the bridges in the downtown area became plugged with debris and were washed out when they could no longer withstand the pressure. Other bridges held, but sustained excessive erosion damage. The floodwaters left behind several feet of mud and debris all along the South Platte flood plain. In Denver, the cleanup job took several months and cost the city over $1 million."

Athmar Park is home to a branch library. Until 1999 the library was housed in a small storefront in the Athmar Shopping Center (1865 W. Mississippi Avenue). In 1999, the current library was relocated into a beautifully remodeled stone building, formerly a church, located at the corner of West Mississippi Avenue and South Tejon Street at 1055 South Tejon Street. The Athmar branch library hosts a Robert Mangold wind sculpture. That sculpture was formerly located at the Denver Art Museum.
The neighborhood has six mosaic games tables created as a public art project by area residents and school children. The game tables are intended to provide gathering places and encourage interaction between area residents. Three mosaic game tables are located at Huston Lake Park and three are located in Aspgren Park; the game boards include chess, checkers, and backgammon boards. The game boards are surrounded by themed mosaics. At Huston Lake: 1) a mosaic quilt patch table commemorates the ladies of the Valverde Presbyterian Church who gathered every Tuesday for over 40 years to create quilts for the less fortunate, 2) a mosaic flower table created by Valverde Elementary school children, and 3) a mosaic view of the mountains from Huston Lake created by neighborhood residents; well-known Colorado oil painter and neighborhood resident, Brenda Hendrix, created the overall design of the mountain view table. At Aspgren Park: 1) a mosaic commemorating the 1965 flood, 2) a mosaic all about "love," and 3) a modern design mosaic.
Alameda Square Shopping Center, 2200 W. Alameda Avenue, was developed in 1959 as Denver's first outdoor mall. When first constructed, the mall included a Ben Franklin dime store, a bowling alley, a furniture store, doctor offices, and more. The very popular Organ Grinder pizza parlor, with its famous two story organ, was located at the center. By 1990, the center was past its prime and declared a blighted site. The center was redeveloped by Brighton Corporation in 2009-11. A public art installation, "Geese," was created by Colorado sculptor Fred Lunger as part of the project.
