The access to Urnes Stave Church is a bit more difficult than any of the others. You can take the very narrow road on the south side of Lustrafjorden, or maybe better, take the ferry across the fjord and walk the few hundred meters up to the church. Urnes Stave Church, built about 1140, is the only Stave Church on the UNESCO World Heritage Site list.
This is the second post about Norwegian Stave Churches.
