Kayaking or Paddleboarding

For couples who want something active, kayaking or paddleboarding on a calm lake or river is hard to beat. You're in nature, there's a mild physical challenge, and tandem kayaking is literally an exercise in cooperation. It works best for daytime dates and people who are at least somewhat comfortable around water. The shared adventure creates a story — and having a "remember when" from the first date is a powerful bonding mechanism.
