From our own checks of every site here, lately about every 15 minutes for nights this month and next, less often further out. A site that opens and is rebooked between two checks isn't counted, so these are floors, and each time is a bound. Cancellations at every campground we log →
Twin Lakes Campground cancellation policy
Cancel by 11:59 p.m. two days before you arrive (Wednesday night for a Friday arrival) and you lose only the $10 fee; after that you also lose the first night. That's Recreation.gov's site-wide rule.

Set an alert for your dates and we check every site in Twin Lakes every 30 seconds. When one opens, you get an email with a direct link to the site and night — you book it yourself, in your own Recreation.gov account.
