Nearing the 100th Street mark on Collins Avenue, Mid-Beach gives way to North Beach. In particular, at 96th Street, the town of Bal Harbour takes over Collins Avenue from Miami Beach. The town runs a mere 10 blocks to the north before the bridge to Sunny Isles. Bal Harbour is famous for its outdoor high-end shops. If you take your shopping seriously, you'll probably want to stay in this area. At 106th Street, the town of Sunny Isles is an appealing, calm, predominantly upscale choice for families looking for a beautiful beach. There’s no nightlife to speak of in Sunny Isles, and yet the half-dozen megaluxurious skyscraper hotels that have sprung up here in the past decade have created a niche-resort town from the demolished ashes of much older, affordable hotels. Farther west are the high-rises of Aventura.
