Drive down Cook Flat Rd for 10 km west of the township past the Lake Matheson turnoff until it becomes an unsealed road for the best view of the peaks of Aoraki/Mt Cook and Mt Tasman. There's a picnic area and a plane table which can be used to identify the different peaks of the Southern Alps.

Take the 4.4-km walk around the lake to see the beautiful reflection of Aoraki/Mt Cook and Mt Tasman on its dark waters. The lake was formed during the last Ice Age retreat by Fox Glacier 14,000 years ago. The track is well maintained, and there are boardwalks and specially-made platforms for getting the right angle for your pictures. The best light is at dawn, and it's about 20 minutes to the first lookout (and 20 minutes back if you don't want to walk the whole way) and 40 minutes to a floating pontoon.
8-hr round trip on a steep marked route through to alpine grasslands that afford views of the mountains, glacier, and the coastline.
The most experienced New Zealand glacier guiding company, offering guided trips onto the glacier. There's the Fox Trot: half-day walk, Flying Fox: heli-hike, Nimble Fox: all-day walk, Fox Trail: Terminal Face walk, Fox It Up: ice-climbing adventure, Chancellor Dome day and overnight heli-treks. The heli-hikes have limited spaces, so booking beforehand could guarantee a spot.
Flights last for 20-40 minutes, from a simple fly-around and glacier landings, to an extended flight for a closer look at Aoraki/Mt Cook, Mt Tasman and a loop towards Franz Josef Glacier.
