The town has a train station and a bus stop.
The drive from Stockholm is straightforward and takes around three hours.
The town itself is walkable. It is also a hub of canoe routes.
The historical town centre. The slate quarry. Måltidens hus, a gastronomic academy housed in what was Sweden's pavilion at the '94 World's Fair.
And the forests and lakes of course.
Take a walk around the lake, head to the swimming area marked on the tourist information office's map and then pick a path through pine and birch forest along side the lake. Swimming in the lake is also on the cards, but far too cold on the damp early autumn morning I was there. Water is crystal and bottom sandy however, so on a sunnier day it might be just the ticket.
Måltidens hus and the nearby Grythytte Qwarn (a watermill museum) offer high-end Swedish food products and crafts. Nearby villages host low-cost auctions and flea markets during the summer.
Grythyttans gästgivaregård,  is a nationally famous inn with great food and furnishing. Lunches are reasonable in price, dinners are more costly, but the height of Swedish cuisine.
The inn noted above can put you up very comfotably, at a price.
There was what seems to be a rather informal campsite by the one of the lakes if that's more your thing.
Loka Brunn is a spa with a swimming park. Public opening times are limited, though.
