A mud bath in Costa Rica
A nice article about travel in Costa Rica mentions this stop for a mud bath:
First we were instructed to enter a small sauna and bake our bodies - this was apparently the proper preparation for the messy business to follow. Next, we gathered around large vats of warm, oozing brownish mud, which we were then instructed to scoop up in our hands and apply to ourselves. It felt a little naughty, this blatant violation of all those childhood instructions to "Stay away from that mud!"
