Yosemite is posting live entrance waits and parking alerts, with Fresno’s Highway 41 South Entrance included. Here’s how Central Valley visitors can use it before they leave home.
Yosemite adds AI wait-time tracker for Hwy 41, 120 and 140 entrances
Key Takeaways
- Yosemite now posts live entrance wait times for South, Arch Rock and Big Oak Flat.
- The Fresno Bee reports the park is using AI to power parking and road updates.
- Visitors can text "ynptraffic" to 333111 for real-time traffic and parking alerts.
- Highway 41’s South Entrance, the Fresno route, is included in the wait-time tool.
- YARTS’ seasonal Highway 41 bus links Fresno to Yosemite as an alternative.
A bug-splattered windshield, inching toward the South Entrance. That’s a July scene many Central Valley drivers know too well. Yosemite National Park now shows real-time wait times for three entrances, a small change with big planning value for Fresno and Madera families who go up Highway 41.
Park officials rolled out the live waits in June for the South Entrance on Highway 41, Arch Rock on Highway 140, and Big Oak Flat on Highway 120. The feature lives on the park’s Current Conditions page, alongside roadwork and closure notes. The text-alert system remains in place too, with "ynptraffic" to 333111 sending updates when lots are full or roads are restricted.
The Fresno Bee reported Thursday that Yosemite is using AI to generate parking, road status and entrance-wait updates. The park’s post promotes the new waits and alert tools, and it points people to the Current Conditions page. The Bee’s framing explains the back end, while the park keeps the message focused on tips.
What changed
In one place, visitors can now see if the South, Arch Rock, or Big Oak Flat entrances are backed up, then decide whether to adjust timing or route. The same page notes scheduled delays, including hazard tree work on Glacier Point Road that started July 21 and is expected to continue through August, which can add 15 minutes on weekdays.
The addition follows months of heavy interest in how the park would manage summer crowds after dropping reservations for 2026. Live waits are a clearer signal than the usual social chatter people rely on before they roll. Worth saving to your phone.
How to use the new tools
Check the park’s Current Conditions page before you leave, then again near Oakhurst or Mariposa where you still have service. If a lot closes or a road slows to one lane, the text system will push an alert when you subscribe by texting "ynptraffic" to 333111. The traffic page also carries photos and guidance about when parking typically fills.
Why this matters in the Valley
Most Fresno-area day trips run through Highway 41 and the South Entrance. Live waits for that gate help decide whether to leave earlier, turn for Highway 140, or park once and ride shuttles instead of circling for a spot. For those who don’t want to drive at all, YARTS’ seasonal Highway 41 line connects Fresno and Madera County stops to Yosemite Valley through late September.
The park’s own example photo shows the line at Arch Rock right after sunrise. You can almost hear idling engines in the trees.
