Mount Cook and Tasman River Lookout is a place to stop and look at the landscape on the way into the Mount Cook area. It is a showcase of New Zealand's majestic landscapes, and the view is what draws people here. The address given is Glentanner, a settlement in the Mackenzie Basin on the road towards Aoraki Mount Cook.
The lookout's attraction is the view itself: the Tasman River, the high peaks of the Southern Alps and the broad valley below. For a visitor on the way to the mountains, it is a stop to take in the scale of the land before going on. The listing's Google rating is 4.7, and the page shows it.
