@Margaret1185 Your place is all about nature, it is the reason why anyone would go there, it should attract those interested in nature. I would emphatically describe it so who comes does so with that understanding.
Anyone coming should already know all about the reality of snakes, racoons, tarantulas, Pterodactyls, etc. in the Great Outdoors, I doubt you will get too many oblivious to that reality.
Enjoy at your own risk' is the theme and if such a sign is required (aka for a liability disclaimer) on the property then add it in an obvious place. Even in the 'Nothing-is-My-Fault' U.S. this probably suffices.
Personally, I am not a fan of being 'The Bearer of Bad News' where is up to me to prepare guests about basic outdoor common sense or survival skills; if you are not already 'there', best not to come. 🙂
P.S. While here, the key to your type of place is to make sure to have plenty of benches (or pergolas and lean-tos), where the guests have a place to sit and watch nature in parallel from the most attractive places.
