I know next to nothing of hiking, so I’d be interested in hearing of your trips and tips and whatever else!
My limited knowledge roughly amounts to go with someone (genuinely) experienced, have more water (and probably food) than you’ll think you need, good footwear, be wary of the mystery berry, and don’t try to pet/touch all the wildlife (no matter how cute they may seem).
Buy walking sticks. I just got a cheap pair from Walmart for when I go mushroom hunting and my god they help out so much. I’m no longer sore and tired after a few hours out there.
