Volcan Villarrica, which is about 15 km from the village. Where Puc n meets the lake, there is a long, wide black sand beach. Puc n has a permanent population of about 2000, but don't let that fool you. The best time to go is probably January, because most Chilean tourists come in February. But there are probably many more months of good weather.
Wooden flowers are a local specialty.
Rollerblading OK, rollerblading isn't on the top of your list of reasons for going to Chile. And for good reason, I found. The only good pavement I found around Puc n was on the highway going east to Parque Nacional Huerqueque. For a few miles there is actually a bikepath on the side of the road, which is great for skating. When that ends you can go about another mile before hitting bad pavement, for a total of maybe four miles each way.
