Most of you are probably wondering, “What is a llao llao?” Good question. According to http://www.enjoy-patagonia.org/
This fungus is preferentially found on the coihue; its hifae (tubular filaments) undermine the bark of the host tree’s branches, forming the characteristic “knots” that can be up to 1 m in diameter. The fungus is edible, and is pear-shaped, white and tasteless when unripe, later becoming orange-yellow, juicy and sweet.
In a Spanish speaking country like Argentina you might expect it to be pronounced “yao yao”, but around here it sounds more like “jao jao” when the locals say it. It is also the name of area west of Bariloche. There is a spectacular hotel there, reminiscent of the Banff Springs Hotel, a municipal park and hill that all share the Llao Llao moniker.
This area is beautiful and it attracts a lot of visitors, but with the all the visitors come tourist prices. We checked on a few excursions, but they were nearly $100 each. We don’t have the budget for that on this trip, so we hopped on a #20 bus and rode it out to the hotel end of the line.
