Atherton Creek is full. Cancellations happen every day.
A Forest Service campground on Lower Slide Lake, just up the Gros Ventre Road from Grand Teton's east boundary — quieter and less contested than the park's own campgrounds, but close enough to draw the same summer crowd.
Full for your dates. Every night you asked for is taken at Atherton Creek.
A free watch checks every 60 minutes, and a site can open and be taken between two checks. An email is how you hear.

How it works
Questions
Is Atherton Creek sold out this weekend?
As of Oct 24, 3:25 AM UTC, Fri, Oct 30 is full and Sat, Oct 31 is full at Atherton Creek. A free watch emails you the moment a cancellation opens either night.
How fast are alerts?
Free: we check every hour, day and night. When a site opens for your nights you get an email with the booking link in it. Priority Pass is $10 once, not a subscription. For one watch, for as long as its dates are open, it checks every 5 minutes instead of every hour, so you hear sooner. A free watch checks every 60 minutes, and a site can open and be taken between two checks.
How many campgrounds can I watch?
As many as you like, on one email address — every campground page has the same form. Each watch is separate, with its own dates and its own one-click stop.
What does it cost?
Watching is free — no card, no account. Priority Pass is $10 once, not a subscription. For one watch, for as long as its dates are open, it checks every 5 minutes instead of every hour, so you hear sooner.
Does it book for me?
No — you get the booking link the moment a site opens; booking stays in your hands, on the reservation system's own site.
How do I stop, or change my dates?
Every email has a one-click stop link. A watch ends by itself the day after your last night, with a note on what it saw. For new dates, subscribe again on the campground page — it takes ten seconds.
