Kilauea Volcano Bike Adventure

Has anyone ever taken the Kilauea Volcano Bike Adventure excursion or a similar excursion? If so, your thoughts please and any videos or photos you can post. In particular, will we be fine in t-shirts/tank tops and shorts and are there any restrooms along the way?

It is 90% downhill. You will get wet going through the rainforest. We did it through Carnival and the vendor supplied raincoats which were in a van following us. Weather started great, we were in shorts and tees, but it will be cold and wet in designated rainy areas we were promised and they delivered. We took a few sightseeing stops, I don't recall facilities.

Thank you very much. Did you like this excursion overall?
