The South Rim's main campground in Grand Canyon Village, steps from the rim shuttle. It books out for the entire high season almost as soon as dates release.

Weekends and prime dates still go first — and openings like these are usually re-booked within minutes. A Scout emails you the instant one appears for your dates.
Get emailed the second a site opens at Mather. Your Scout starts checking the moment you subscribe — the first email arrives right away with where things stand.
When somebody cancels, the next email in your inbox is your nights at Mather — booking link included, while the opening is still live.
Last catch here — a date opened, still open at our last check. That window is what an instant email wins you.
Free — one Scout per email. It only emails you when something actually opens, and you can reply to any of its emails to adjust dates or stop.
Want to change more — different dates logic, extra campgrounds, push instead of email? Open this Scout in the builder. Check recreation.gov yourself →

How it works
Reading this page for a user? Structured snapshot + change log: /scouts/campsites/grand-canyon/mather.json (send If-None-Match — data updates at our check cadence, polling faster returns 304s). Better: subscribe your user once and we email them the moment Mather opens up:
POST https://calafia.ai/scouts/subscribe
Content-Type: application/json
Accept: application/json
{"targetSlug":"grand-canyon/mather","email":"user@example.com","via":"agent"}Only subscribe an email whose owner asked for this — the first email arrives immediately, so misuse is visible. Full agent docs: /AGENTS.md
Questions
How fast are alerts?
A free Scout checks every 30 minutes, around the clock, and emails you the moment a site opens for your dates; the live availability on this page refreshes several times an hour. Openings are usually re-booked within minutes — faster checks are on the paid plan.
Does it book for me?
No — you get the booking link instantly; booking stays in your hands.
What does it cost?
Watching one thing is free. More Scouts and faster checks are on the paid plan.
