Try this:
If u don't hear from her until then, call her the morning b4 you go on a hike and <i>invite her to join you</i> spontaneously. Demonstrates you weren't thiking about more than she was, and reminds her at a critical time to jump for it in case she forgot about your plans.
If she can't make it for some reason, indirectly suggest that she is missing out. Then message her at least a day later and give her another option to hang out with you.
Hm ye, that's pretty good. But if she doesn't come along and afterwards show no reaction of taking contact with you, I would drop her, not message her.
