Jenny Lake is booked solid. Cancellations happen every day.
Tent-only sites at the base of the Tetons, steps from the lake — the single most contested campground in the park. When we measured in July 2026, September was 100% reserved: not one site-day left.
Right now: open sites on 4 dates in September 2026.

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 Jenny Lake. 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 Jenny Lake — booking link included, while the opening is still live.
Still measuring how fast cancellations here get rebooked.
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.

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.
