Aspenglen is full. Cancellations happen every day.
A smaller, quieter campground near the park's Fall River entrance on the north side of Estes Park. Fewer sites than Moraine Park or Glacier Basin makes summer weekends tight.
Full for your dates. Every night you asked for is taken at Aspenglen.
A free watch checks every 60 minutes, and a site can open and be taken between two checks. An email is how you hear.
Your dates are already filled in below — just add your email.

Over the last 30 days, our checks saw 10 cancellations open up at Aspenglen (about 2 a week), covering 10 nights. Of the 10 nights we saw open and then close again, 40% were gone within an hour of us spotting them, 70% within six hours and 80% within a day. 30% of the nights that opened were Friday or Saturday nights.
These are counts of what our own checks saw (about every 15 minutes); an opening that appeared and was taken between two checks is not in them, so treat every figure as a floor.

Watching since Sep 8, 2026. Our shared checker refreshes about every 15 minutes — that is the measurement; your watch is the alert. A free watch checks every hour; a Priority Pass watch checks every 5 minutes. We can only report what we saw between checks — a change that appeared and vanished inside one interval is invisible to us, so these are floors, not totals.

How it works
Questions
Is Aspenglen sold out this weekend?
As of Oct 22, 3:17 AM UTC, Fri, Oct 23 is full and Sat, Oct 24 is full at Aspenglen. A free watch emails you the moment a cancellation opens either night.
How often do sites open up at Aspenglen?
Over the last 30 days, our checks saw 10 cancellations open up at Aspenglen (about 2 a week), covering 10 nights. Of the 10 nights we saw open and then close again, 40% were gone within an hour of us spotting them, 70% within six hours and 80% within a day. These are counts of what our own checks saw (about every 15 minutes); an opening that appeared and was taken between two checks is not in them, so treat every figure as a floor.
When do cancellations show up at Aspenglen?
30% of the nights that opened were Friday or Saturday nights.
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.
