Go on a kayak or 4WD tour for fascinating natural history on and around the ecologically and historically significant Wairau Lagoon, 10 minutes' drive from Blenheim. Rare birds and the muppetty royal spoonbill may well be spotted. The semi self-contained 'Retreat' provides accommodation for up to four (double/quad $250/450), while the 'treehouse' offers accommodation for up to three (double/triple $200/250).

Breakfast is an extra $20 per person, and both accommodation options are next to the Opawa River.
