Denny Way meets I-5 forms the "peak" of the Denny Triangle neighborhood, while 5th Avenue extends along the southern end of the triangle. Just beyond the neighborhood sits Belltown and Pike Place Market. As Seattle's fastest-growing neighborhood, Denny Triangle features newer, modern apartment buildings, trendy shops and restaurants, theaters, bars, and more. It includes part of the outdoor shopping mall, Westlake Center, a walkable strip filled with high-end shops and boutiques. As a whole, Denny Triangle is extremely pedestrian-friendly and is considered a walker's paradise.
You won't find single-family homes in Denny Triangle -- this ultra-urban, hip neighborhood consists of apartment complexes and condos, many in high-rise buildings. This neighborhood provides several other neighborhoods within walking distance, including Downtown Seattle, Capitol Hill, Pike Place Market, Belltown, and South Lake Union.
Here's an interesting fact: Denny Triangle used to be one of Seattle's seven hills. In the late 1800s, city planners decided the hill had to go and began a major regrading project. The Denny Regrade took 22 months and covered nearly 40 blocks.
