1: Explore the Old Cement Works at Warkworth
We heard about a gem from a friend who likes to make women swoon, starting with a ride on the back of his motorcycle. However, you don't need the leathers to pull this one off - any mode of transport will do. Jump from the grassy banks into the swimming hole, explore the ruins and chill out with a packed lunch in the sun. Take signposted Wilson Rd off Pulham Rd and enter the Old Cement Works by an unsealed road leading to a carpark.
2: Go on a boat ride
There's something romantic about the gentle sway of the sea as you take in the scenes of the Hauraki Gulf. Get yourselves a seat either on a ferry to Devonport or Waiheke Island. Once there, hire bikes - tandem or solo - and spend the morning cycling around the town. Pick up a stash of salty fish and chips rolled up in paper and find a spot seaside to top off an outdoorsy date that shows you have put your thinking cap on.
