Walk the Granite Trail behind Springfield at Whitney Oaks on a cool September morning and you'll probably see three things: exposed granite boulders that formed somewhere between 130 and 150 million years ago, a few grazing sheep if you catch the spring rotation, and at least one neighbor who tells you this whole hillside used to be a golf course. That neighbor is right, but probably not about the golf course they're picturing.
Here's the mix-up. There are two old golf courses within a few minutes of each other in this part of Rocklin, and they had completely opposite fates. One is still very much a golf course. The other stopped being one nearly two decades ago, sat vacant long enough to become a fire hazard, and is now the reason you can walk a paved path instead of a fairway. If you live in Springfield or elsewhere in Whitney Oaks, knowing which is which matters, because only one of them just went through a public planning process that's about to add a Veteran's Memorial, an amphitheater, and a mountain bike park a short drive from your front door.
The Course You Actually Look At
Whitney Oaks Golf Club, the 18-hole course that edges the Whitney Oaks subdivision and gives Springfield its golf-adjacent lots, opened in 1997 and was designed by Johnny Miller and Fred Bliss. It's owned today by the United Auburn Indian Community, the tribe behind Thunder Valley Casino Resort, which bought the course back in 2012 for $3.95 million as part of rounding out Thunder Valley's resort offerings for out-of-town guests. That's the course with the 15,000 square foot clubhouse, the Pyramid Bar & Grill, and the Thursday prime rib special. It is not going anywhere. It is not the subject of this post.
The Course That Disappeared
The other Whitney course has a different name if you look closely: Sunset Whitney Golf Club, not Whitney Oaks. It opened back when Rocklin's population sat around 1,600 people. By the time the city stepped in, the course had failed as a business and sat abandoned long enough to become an overgrown fire risk that neighbors had been complaining about for years. In 2017, the City of Rocklin bought the property for $5.8 million, using state Proposition 68 recreation bond funds to help pay for the conversion, and set out to turn 184 acres of former fairways into what officials have described as their version of a Central Park for the city.
That property is the Sunset Whitney Recreation Area, and its main entrance sits at 4201 Midas Avenue, a few minutes from Whitney Oaks by car. The old cart paths and bridges became the West Trails, which now cover roughly two and a half miles and are the most walked stretch, according to trail data trackers that track foot traffic through the park. In August 2022, the city opened Phase I of the East Trails, adding about a mile of ADA-accessible pathway and opening up roughly 30 more acres that had been fenced off since the golf course closed. The city's own project timeline confirms the East Trails are now fully open, effectively doubling the paved mileage available compared to what existed when the park first opened.
Then And Now, In One Table
| Sunset Whitney Golf Club (pre-2017) | Sunset Whitney Recreation Area (today) | |
|---|---|---|
| Owner | Private golf operator | City of Rocklin |
| Access | Members and paying golfers | Free and open to the public |
| Condition | Vacant, overgrown, cited as a fire risk | Maintained trails, informational kiosks at the Argonaut entrances |
| Primary surface | Fairways and cart paths | Paved and decomposed granite walking paths |
| Signature feature | 18-hole course | West and East Trail loops totaling roughly 3.5 miles |
A Third Trail System With Its Own Name
There's a third piece to this that's easy to miss if you've only ever heard the word "Whitney" used loosely. The trails that wind directly through the Whitney Oaks and Springfield developments themselves, the ones that pass the golf course you can see from your yard, are a separate 215-acre common area maintained by the Whitney Oaks Community Association, not the city. Those are the Foothills Trail and Granite Trail, the ones with the steep climb up to Black Oak Drive and the 45-step staircase near Abby Road. Two longtime residents, Ken and Bea Morrow, along with a neighbor named Earl Brabb, put together the community's own trail guide because they wanted better documentation of these paths for their neighbors. That guide lives on the Whitney Oaks HOA site, separate from anything the city manages.
So to be precise: one golf course still operates and belongs to a casino resort. One golf course died and belongs to the city now, as a park. And the walking paths inside your own subdivision belong to your HOA. Three different owners, three different rulebooks, one overlapping name.
What's Actually Changing, And Why It's Not Your HOA's Trails
The part worth paying attention to right now involves the city-owned park, not the private community trails. In January 2026, Rocklin released a full Master Plan for the Sunset Whitney Recreation Area for public environmental review, filed as a Mitigated Negative Declaration with the state's CEQA clearinghouse. The comment period ran from January 23 through February 23, 2026, so as of this writing the review window has closed and the project is moving into its next planning stage.
The plan centers on what the city calls the Hub Area, the footprint where the old golf course's parking lot, clubhouse, tennis courts, and driving range used to sit off Midas Avenue. Proposed additions include a Veteran's Memorial with honor walls and a rose garden, an outdoor amphitheater with natural terrace seating, an adventure park and mountain biking area, an art walk, a recessed plaza built around a dry creek bed, and a roughly 18,000 square foot multi-use recreation center. There's also a natural preserve area planned for wildlife viewing, with interpretive panels along the path.
None of this touches the golf course you actually see from Springfield. None of it changes your HOA's Foothills and Granite Trail network either. It's an expansion of the free public park a short drive away, on land that spent years as a hazard before it became a place people go to relax.
As deputy Parks and Recreation director Kevin Huntzinger put it when an earlier phase of trail funding came through:
"This grant funding provides a great opportunity to open additional portions of SWRA for everyone to enjoy."
That sentiment has held up. Every funding round since 2017 has gone toward opening more of a property that used to be closed off to everyone.
Timing Your Walk
If you're planning to check out the West or East Trails before the Hub Area construction ramps up, a few practical notes from people who walk it regularly. The trails sit mostly exposed with little shade, so cooler hours at dawn or dusk are the more comfortable window, especially once the afternoon heat sets in later this month. Following winter rains, seasonal ponds and creek flow through parts of the park that stay dry the rest of the year, so late winter and early spring tend to be the most scenic stretch if you're bringing a camera. Parking is available at the main Midas Avenue entrance, with additional access points feeding in from the Argonaut side of the park.
If you're sticking closer to home on the Foothills and Granite Trail loop inside Whitney Oaks itself, park at the public lot for Pleasant Valley Creek Park along Whitney Oaks Drive. The granite outcropping near that trailhead is one of the more striking formations in the immediate area, and the goats and sheep that show up during the managed grazing season tend to cluster along the flatter stretch past the steepest climb.
Two trail systems, two very different owners, and only one of them just went through a public planning process that will reshape it for the next several years. Worth knowing before someone tells you the golf course is turning into a park. It already did, just not the one you were picturing.
