Wet is as wet as you would like, from splashy to chin deep, such is the variety from Brownley :)
The High Level trip has a bit of waist deep, Haggs gets to chest deep near the entrance, getting to Guddamgill is waist deep; going to the Brownley flats and the blue lagoon is just splashy.
I personally wouldn't bother with a wetsuit for most of Brownley, you aren't in deep water for very long. My sanity may of course be questionable 🙂
Don't look so embarrassed, it's a family trait...
