Get the reminder by email
One email the week before the big Mountain West dates (each Angels Landing seasonal lottery, Havasupai's on-sale day, and Rocky Mountain's first timed entry release once it's announced). Nothing else.
Before any reminder, you'll get one email asking you to confirm. It comes from New England Reservations (hello@newenglandreservations.com), our sister site. Unsubscribe anytime. See the privacy policy.
