Even though I am from Western PA, I am a horrible hill climber. The hills here are STEEP. But lots of climbs out west are long but you barely know they are there. The Selkirk Loop for example has pretty much only 2 or 3 hills that will get your attention. One just outside of Kelso, one just outside of New Denver and one in Nelson. Altitudes are still low enough that you won't be bothered much and there are a lot of great views.

There are probably prettier areas but not many where there is an easy ride, ample amenities and great views.
