How to say "boardwalk" in Japanese

• 木道もくどう
  nounCovers a boardwalk in the literal sense of a wooden path laid over marshy or wet ground, like a wooden causeway in a nature reserve. This is the natural choice for such walkways, though the word itself is less common.
• ボードウォーク
  nounA loanword matching 'boardwalk' directly, typically the seaside promenade sense of the English word. It is a less common way to say this in Japanese, so it may not always be the word you want.

Use 木道 for a wooden walkway built over marshy or soft ground, and 「ボードウォーク」 for a boardwalk in the seaside-promenade sense; the latter is itself not especially common in Japanese.
