This is a smaller temple, easily accessible from Lin An Road 临安路, which is one of the main streets that runs through the old part of town. Its easy enough to duck in here if you are walking between major scenic spots, such as the Confucius Temple, not far away.
Not sure I'd make a special point of visiting here unless you are in the area. I didn't find anything that made it unique, though it's attractive and well maintained. No admission was changed when I visited, during the week in mid May.
