The Towns In California's Sierra Nevada Where Retirees Are Actually Moving To
California added more than 800,000 seniors to its Medicare rolls in just five years, and plenty of them are heading for the hills, just not very high into them. In the Sierra Nevada, the real growth is happening in the western foothills, in the counties of Placer and El Dorado, where the older population is rising faster than in California as a whole. Farther up the range, in quieter counties such as Tuolumne and Mono, the change is much slower. The towns drawing retirees share a simple formula. They pair mountain views with a short drive to a hospital and a highway back down to Sacramento. That pull is strong enough to stand out even as California loses more senior households to other states than it gains.
El Dorado Hills
No town in the Sierra foothills added more older residents. El Dorado Hills gained roughly 2,000 people aged 65 and older between the two most recent Census surveys, and its share of seniors arriving from another county or state each year runs about twice the California average. Most of them come from elsewhere in the state, and Sacramento County is El Dorado County's largest source of newcomers by a wide margin, followed by Placer County and the Bay Area's Santa Clara and Contra Costa counties.
The town was built for this. El Dorado Hills is a collection of planned neighborhoods on rolling oak hills above Folsom Lake, and it includes Heritage El Dorado Hills, an age-restricted community for residents 55 and older. Its Town Center holds shops, restaurants, and a cinema around a man-made pond, and hospitals in neighboring Folsom are a short drive west.
Placerville
Placerville is the El Dorado County seat, and it draws older newcomers at about four times the statewide rate, the highest of any town on this list. Its senior population grew by more than 350 between surveys, and about two-thirds of the recent arrivals came from elsewhere in California.
The appeal is practical. Marshall Medical Center, the county's main hospital, is in town, and Highway 50 runs straight down to Sacramento. Placerville's Gold Rush-era Main Street centers on a Bell Tower dating to the 1860s, and the orchards and wineries of Apple Hill are a few minutes east. At Gold Bug Park, the city runs a former gold mine that visitors can walk into.
Auburn
Auburn sits where Interstate 80 starts its climb into the mountains, and it pulls in older residents at about four times the state average. Its senior population grew by more than 200 between surveys, mostly with movers from elsewhere in California. Placer County, which includes Auburn, had the fastest senior growth of any Sierra county, and Sacramento County sends it more newcomers than anywhere else.
Sutter Auburn Faith Hospital serves the town, and the domed Placer County Courthouse, completed in 1898, stands over a historic Old Town of brick shops and cafes. Below town, the North and Middle Forks of the American River meet inside the Auburn State Recreation Area, where trails follow the canyons.
Grass Valley
Grass Valley is running ahead of its own county. Nevada County's senior Medicare enrollment grew only about 7% over five years, among the slowest in the range, yet Grass Valley added nearly 600 residents aged 65 and older between surveys, and seniors now make up about a third of the town. Newcomers to Nevada County come mostly from Placer and Sacramento counties, with the Bay Area's Contra Costa and Alameda counties next.
Much of that growth gathers around services. Sierra Nevada Memorial Hospital is in town, and Eskaton Village Grass Valley offers independent living, assisted living, and memory care on one campus. Empire Mine State Historic Park, one of California's richest former gold mines, sits on the edge of town, and a walkable downtown of brick storefronts and theaters keeps daily errands close.
Mariposa
Mariposa is small, so its numbers move quickly. The unincorporated town's senior population grew by about half between the two surveys, and residents 65 and older now make up roughly two in five people in town. Its senior newcomers all came from elsewhere in California, and Mariposa County draws most of its movers from the San Joaquin Valley counties of Merced and Stanislaus.
Mariposa County's overall senior growth was modest, so the town is concentrating the change. John C. Fremont Healthcare District operates a small hospital in Mariposa, and the Mariposa County Courthouse, built in 1854, is the oldest courthouse still in use in California. Yosemite National Park's Arch Rock entrance is about an hour's drive up the Merced River canyon.
Three Rivers
Three Rivers breaks the pattern. Unlike the other towns on this list, most of its recent senior arrivals came from outside California rather than from elsewhere in the state. The small community at the forks of the Kaweah River added about 100 residents aged 65 and older between surveys, and seniors now make up about a third of its population.
The town is the gateway to Sequoia National Park, whose Ash Mountain entrance is just up the road. Daily life is quiet and spread out along the river, with galleries, a historical museum, and Lake Kaweah nearby. For hospital care, residents drive about 35 miles to Kaweah Health Medical Center in Visalia.
Foothills Over Mountains
In the Sierra Nevada, retirees are mostly choosing the lower slopes. The fastest growth is in Placer and El Dorado counties, especially in towns along Interstate 80 and Highway 50 with a hospital in town or close by, while the higher, more remote counties are adding older residents more slowly than California as a whole. For foothill towns like Placerville, Auburn, and Grass Valley, that means steadily rising demand for medical care, senior housing, and transportation, while smaller places like Mariposa and Three Rivers will feel even modest growth in their limited local services.
