Is there any cover in case if rain? Like a pavilion...thinking of a picnic but t-storms in the forecast.

There's a small outdoor pavilion near the entrance with a couple picnic tables. It's just a roof, though it should keep you out of the rain

like Xavier said there is a little pavilion, covered seating area right before you walk into chasm

There's a pavilion right before the chasm, but I don't know how much cover it'll give if there's also wind in the forecast.
