Last Saturday morning, the parking lot at 111 Wiggins Way had open spaces before 10 a.m. for the first time since Memorial Day. Anyone who has tried to get a spot there in July knows that's not nothing. The Wibit Water Park had just dropped from daily to weekends-only, and the crowd that shows up for inflatable towers and a $20 wristband simply wasn't there on a Tuesday anymore. But the disc golf course a few hundred yards away was as busy as ever, and two guys were loading mountain bikes off a rack like it was any other week in June.
That gap between what looked like a quiet lake and what was actually a full one is the whole story of Grindstone in late summer. Most people who live near it assume the place shuts down in one motion around Labor Day, the way a beach town rolls up its sidewalks. It doesn't. Grindstone Lake winds down in three separate steps, on three separate dates, and each one changes something different. If you're only tracking one calendar, you're going to miss two of them.
Three Closing Dates, Not One
The first step already happened. August 8 was the last day of daily public swimming at the Ruidoso Municipal Pool, and it's also when the Wibit Water Park stopped operating every day and switched to weekends only, a schedule it holds through Labor Day. That's the shift you felt in the parking lot last weekend.
The second step is coming up fast: the Ruidoso Grindstone Trail Runs land on August 22, the last big organized event tied to the lake's name before the calendar turns toward fall.
The third step is the one most residents actually think of as "the end of summer," and it's still three weeks out. Paid parking at Grindstone has been in effect since May 23, and it doesn't lift until September 7, the same day the Wibit closes for the season entirely and the recreation area drops into low-season hours of 5 a.m. to 11 p.m., no parking pass required.
Here's what that looks like laid out against each other:
| Date | What ends | What keeps going |
|---|---|---|
| Aug 8, 2026 | Daily public swim, daily Wibit hours | Weekend Wibit, all trails, disc golf, fishing |
| Aug 22, 2026 | Downtown race weekend traffic | Everything at the lake itself, unaffected |
| Sept 7, 2026 | Wibit season, paid parking, permit requirement | Hiking, biking, fishing, boating, disc golf |
Three different amenities go quiet on three different Tuesdays, weeks apart, and none of them touch the parts of Grindstone that people who live nearby actually use most.
The Race Named for the Lake Doesn't Start at the Lake
If you've seen the flyers for the Grindstone Trail Runs and assumed the start line is at Wiggins Way, it isn't. This year marks the 12th running, and it starts and finishes at Wingfield Park in Midtown, not at the lake itself, even though the course borrows the Grindstone name and, in the longer distances, some of the surrounding terrain. Runners choose from a 13.8-mile Half Marathon Heavy, an 8.5-mile, a 4-mile, or a Kids' Dash.
The event has been running since 2014, backed by the Village of Ruidoso, Lincoln County, and the U.S. Forest Service, and it exists to raise money for All-Season Adaptive Sports. Over the past eleven years it's generated more than $60,000 for that cause. If you live along the trail system and you're expecting extra cars at the Wiggins Way lot on the 22nd, don't. The traffic that morning is downtown, not at your trailhead.
What Never Had a Season to Begin With
Here's the part that changes how you should think about the lake once the Wibit crowd thins out. Grindstone's disc golf course is 27 holes, par 81, heavily wooded, and it's the host site for the annual New Mexico Disc Golf Championships. None of that runs on a summer schedule. It's free to play year-round, and it was one of the only amenities that stayed open even during the IRONMAN 70.3 closures in early July, when the lake itself, the Wibit, and the main parking area were shut down for a full week for the event. Hikers and disc golfers got in that week through the Grindstone Park Disc Golf Course lot at 509 Resort Drive and the Fisherman's Trail, while the main lake reopened the following Monday.
Fishing runs the same way. A New Mexico license is required for anglers 12 and older, shore hours are 5 a.m. to 11 p.m., and none of it depends on which month the calendar says. Boating is allowed year-round too, with electric trolling motors permitted at no-wake speed and a 19-foot length cap on vessels, a rule that's stricter on neighboring Alto Lake, where only non-motorized boats are allowed at all.
Put together, this means the version of Grindstone that has no off-season is exactly the version that gets better once the water park traffic disappears after Labor Day. Cooler mornings, empty trailheads, and a disc golf course you don't have to share with a line of Wibit ticket holders.
The Trail System Is Bigger Than the Old Signage Admits
There's a real discrepancy worth knowing about if you ride or hike here regularly. The U.S. Forest Service's own trailhead documentation for Grindstone still describes roughly 14 miles of custom-built trail. But the current tourism copy for 2026 puts the system at 18 miles, a jump that isn't a rounding error. It reflects new construction: connector trails built by EcoServants off Carrizo Canyon Road at Mud Canyon Road, added as free public access points into the existing Grindstone network.
If the mental map you're working from is a few years old, or if you learned the trails from a printed handout at the parking lot kiosk, you're missing roughly a fifth of what's actually rideable now. The Mud Canyon access point in particular opens a different entry into the system than the traditional Wiggins Way trailhead, which matters if you've been fighting for parking at the same lot every weekend without realizing there's another way in.
Fall Is When the Birds Show Up
One more thing that has nothing to do with water park hours: Grindstone has a dedicated Osprey viewing area, and fall is one of the two windows, alongside spring, when the birds are most active on the lake. The Village's own parks department notes that ospreys are the most common raptor sighting here, diving for fish during their migration in spring and fall, alongside regular appearances from black bears, mule deer, elk, blue heron, and the occasional bald or golden eagle. September, right as the parking fees lift and the crowds thin, is close to the best month of the year to actually see this.
What This Means If You Live Here
None of this is a reason to change how you use Grindstone Lake. It's a reason to stop treating it like a single seasonal switch. The water park closes in stages you can set a calendar to. The race on the 22nd is a downtown event borrowing a lake's name. The disc golf course, the fishing, and the trail system never stopped running, and the trail system itself has quietly gotten bigger than the old paperwork suggests. September, when everyone else assumes the lake goes quiet, is actually when the part of it with no season at all starts to shine, and the ospreys show up to prove it.
If you're weighing whether a home near Grindstone fits how you actually want to spend your weekends, that's a conversation worth having with someone who tracks these details as closely as the trail signage does.
