Wild On The Fly is bound for Alaska in this episode, where the crew are chasing big Rainbow Trout and Grayling on the Copper River in Bristol Bay. The Rainbow River Lodge is a hub for North American fly fisherman, where this time of year the Sockeye Salmon run in their millions. Living among these bright red travellers are the real prize, perfectly spotted rainbow trout growing to massive sizes. The crew then fly across Lake Clark to the Kijik River for a unique day of dry fly fishing for big Grayling, which make an appearance within millimetres of the world record. Sharing the banks with Grizzly bears upwards of 1500 pounds, barely a casting distance away… it doesn’t get wilder than this.
