Mt Rainier's main eastern entrance is the gateway to Sunrise, which at 6400ft marks the park's highest road. Thanks to the superior elevation here, the summer season is particularly short and snow can linger well into July. The area is also noticeably drier than Paradise, resulting in an interesting variety of subalpine vegetation, including masses of wildflowers.
The views from Sunrise are famously spectacular and – aside from stunning close-ups of Mt Rainier itself – you can also, quite literally, watch the weather roll in over the distant peaks of Mts Baker and Adams. Similarly impressive is the glistening Emmons Glacier, which, at 4 sq miles in size, is the largest glacier in the contiguous USA.
