Bend is more Central Oregon, but still an awesome place to go fishing. The Fall River is a lot of fun to fish, but can be very technical due to the clarity and smart fish. The Deschutes is always fun to fish.
If i were you, i would check the fishing reports from the local fly shops.

Good luck. The Metolius can be a difficult place to fish. It always seems one have to put some time before the river gives up any of its residents. Gorgeous river though.
There are a ton of place to fish the Deschutes. There is some decent access near La Pine state park and even in Bend as well.
If you head out of Sunriver on Century blvd, you can hit the Fall river at the park and the hatchery. You can also continue on to the D.
