This is a popular walk, and for good reasons. It's free, has stunning views, great picnic spots, has historical significance, and takes less than two hours to do! Cook's Cove Walk is in Tolaga Bay, home of a famous wharf, and enormous ice creams from the dairy (seriously, their single scoop icecreams were double scoops!)
I first went to Morere Hot Springs when I was a kid. In the decades since I last visited, it has changed from childhood memories but it still has great hot pools, incredible bush, and is a wee slice of paradise in the middle of nowhere!
800 steps up. Sounds like a lot but it goes surprisingly quick and the view at the top is absolutely worth it. The East Cape Lighthouse walk also has quite possibly one of the most picturesque drives to get to it, following the road around the coast and I almost guarantee you'll start to imagine yourself owning a bach (holiday home) here as the beaches are glorious and it's so easy to find a wee spot away from the other 10 people that happen to be on the beach at the same time as you!
