Fly fishing near King Salmon, AK in July

I'm heading to King Salmon, Alaska, in July and have a free morning before my afternoon flight. I want to fit in a half-day guided fly fishing trip on the Naknek River.

I’ve already booked bear viewing at Brooks Falls and the Valley of Ten Thousand Smokes tour, so this would be the perfect way to end my trip!

A few questions:

- Would you recommend any guide services for a half day on the Naknek in July?

- Is it realistic for a beginner to have a good experience with just half a day?

- Sockeye and rainbow trout seem to run in early July... is that correct?

This trip has been a bucket list experience, so I want to make the most of that last morning!
