The city is bounded by the Atlantic Ocean on the east and the Intercostals Waterway on the west. Almost one million vacationers visit Sunny Isles Beach annually to enjoy the 2 ½ mile-long fine sand beach and outdoor amenities such as water sports, boating, fishing, and tennis as well as the abundant shopping, dining and lodging. The weather is tempered somewhat by its proximity to water; the extreme tip of Florida and the Florida Keys border on a true tropical climate. The city is experiencing a major redevelopment renaissance on the east side of Collins Avenue, the main thoroughfare. The city is building parks, improving the infrastructure and laying the groundwork for future redevelopment. Sunny Isles Beach is a major center of South Florida's Russian community, with a plethora of Russian stores lining Collins Avenue. The city is sometimes referred to as Little Moscow because of its many Russian and Russian-descended residents.
