As of October 1, Calaveras Big Trees State Park is closed south of the Stanislaus River for prescribed burning. That shuts the South Grove Trail, the Beaver Creek area, the Bradley Grove Trail, the fire road around the South Grove, and the Walter W. Smith Memorial Parkway south of the river. State Parks has not posted a reopening date. Its earlier announcement says closures stay in place "until conditions favor reopening."
The Big Trees Village Rec Center season runs Memorial Day through Labor Day, so for anyone in the village the pools have been closed for a month. For the rest of October, the open part of the park is the North Grove side. If you walk with a dog, it gets smaller still. The open area that fits the dog rules is the network of fire roads near the North Grove, not the famous loop itself.
The Closure Map, Line by Line
State Parks and CAL FIRE planned four treatment areas totaling about 780 acres, in the South Grove area, North Grove Meadow, and West Moran. The announcement lists these closures during and after burning:
- South Grove Trail
- Beaver Creek area
- Bradley Grove Trail
- Fire road around the South Grove
- Walter W. Smith Memorial Parkway south of the Stanislaus River
- West Moran road at the park boundary with Upper Moran Road
That list covers more than one trail. The South Grove loop runs 5.5 miles, and the Bradley Grove adds a 2.5-mile loop that starts from the same trailhead. The Beaver Creek area also has one of the park's designated picnic areas, and Beaver Creek is one of the park's two named trout waters. For now, the longer walks, the creekside picnic spot, and the Parkway drive out to them are all closed. State Parks also says other burn units may bring additional closures, so this list could get longer.
Why the South Grove Is Burning Again
The South Grove was burned two years ago. In October 2024, crews treated 1,145 acres of a planned 1,317 in the South Grove. This year's burn goes back over acres that "did not burn well enough to reduce fuel and promote giant sequoia regeneration," and also treats additional acres nearby.
Crews have already done prep work at the trees themselves, clearing heavy fuel and organic matter away from the bases of large giant sequoias. State Parks describes prescribed fire as part of a long-running stewardship program that dates to the park's opening in 1931. Its stated goals are new sequoia growth, healthier soil, better wildlife habitat, and protection for park infrastructure.
So the closure is a second pass on work started in 2024. Every burn depends on weather and air quality, and the department reschedules if conditions aren't right for burning and smoke dispersal. That's why no one has posted an end date.
The announcement names Big Trees Village, along with Arnold, Dorrington, White Pines, Blue Lake Springs, and Love Creek, as communities that may see smoke. State Parks says burns are coordinated with the Tuolumne County Air District, that smoke near the burn area on ignition days "should not be a cause for alarm," and asks people not to call 911 about it. Smoke can also linger for a while after active firing stops.
What the Park Lists as Open
The park's trails page currently lists these as open:
- North Grove Trail
- Grove Overlook Trail
- Three Senses Trail
- River Canyon Trail via the North Grove Trail
- Fire roads near the North Grove
- Lava Bluffs Trail
These trails cover a lot of range. The North Grove Trail is a level 1.7-mile loop, wheelchair accessible when weather allows, and takes at least an hour. It passes the stump of the Discovery Tree, the Empire State Tree, and the Father of the Forest log. The Grove Overlook Trail branches off near marker #2, climbs and parallels the main trail for about half a mile, and rejoins near marker #13. The Three Senses Trail is a few hundred yards long, sits beside the Big Stump, and has printed and Braille markers.
The big outings are the other two. River Canyon is an 8-mile round trip with more than 1,000 feet of elevation change. For now, use the approach from the North Grove, since that's the route the open list names. Lava Bluffs is a 2.5-mile lollipop with steep sections and rough footing in places.
The North Grove Meadow is one of the four burn units, and the meadow boardwalk is not on the open list. Treat its status as unknown until the park says otherwise.
The Walk That Works With a Dog
This is where the open map gets smaller. The park's pet rules say dogs are not allowed "on any trails or in giant sequoia groves," near the river or creeks, in the open forest and meadows, or in environmental campsites. The rule includes dogs in strollers and backpacks. Every trail on the open list above is off-limits with a dog.
Leashed dogs are allowed on fire roads, paved roads, in the regular campgrounds, and in day-use picnic areas, and the leash can be no longer than six feet. The park describes fire roads as gated, dirt-surfaced, about as wide as a regular road, and open to bikes. It says the park has dozens of miles of them along the Parkway, by the South Grove, and around the North Grove. Two of those three areas are now inside or next to the closure. The fire roads near the North Grove are still open.
So the realistic October walk with a dog is a gated dirt road on the north side of the park. The groves themselves are a separate trip without the dog. With questions, the park number is (209) 795-7980.
Dates to Check Before You Go
Construction and scheduling make a few days this month different from a normal visit:
- Now through at least mid-October. Construction near the Visitor Center is limiting parking and making noise during the day.
- October 10. The park lists a North Grove Guided Hike.
- October 14. The Visitor Center is closed for a planned local power outage.
- October 17 and October 24. More North Grove Guided Hikes are listed.
- First significant snowfall or December 1, whichever comes first. This is the park's standing rule for closing the Walter W. Smith Parkway for winter. It usually reopens May 1 or later if snow remains.
The park's event listing doesn't show start times or meeting points for the guided hikes, so check parks.ca.gov the week of. Visitor Center hours also differ by source. State Parks lists 10 a.m. to 4 p.m. for October through March. The Calaveras Big Trees Association, which runs the bookstore and gift shop, lists 10 a.m. to 5 p.m. Plan around the earlier time. Day use is $10 per vehicle, or $12 on holidays, and runs sunrise to sunset. Event calendars outside the park may still show South Grove outings this month. The October 1 closure notice is the one that governs.
Food Is a Drive This Year
The Sequoia Snack Shack is closed for the 2026 season, according to the Calaveras Big Trees Association. For a sandwich after a North Grove morning, the nearest options are along Highway 4 in both directions.
Toward Arnold, Big Trees Market & Deli is at 2182 CA-4 and posted a weekly ad this week with specials running through October 6. Giant Burger, at 846 California Highway 4 in Arnold, lists daily hours of 11 a.m. to 7 p.m. Heading uphill, Camp Connell General Store is at 4036 Old Highway 4. It carries groceries, café food, and beer and wine and says it's open seven days a week. Its own hours page is the one to check.
If you own a cabin in Big Trees Village and rent it out through the fall, your guests will be asking these same questions about what's open, where the dog can go, and where to eat. Kip Machado and the Cedar Creek team keep track of park notices like these for the owners and guests we work with, and we're glad to help you set up a guest guide that matches this season.
