and environmental-education activities. Youth programs include public school field trips to the park's urban farm and saltmarsh, environmental and garden tours and workshops, and various outdoor arts and crafts programs. In addition, RIPA hosts Randalls Island Kids camp, a free six-week-long summer camp for children from community organizations in East Harlem and the South Bronx. Programming for the general public includes movies nights in the park, historical and environmental tours, outdoor yoga, and large festivals, including the Cherry Blossom and music festivals. Randalls Island Park contains over 8 miles of pedestrian and bike pathways, the majority of which run along the scenic waterfront perimeter of the island. With connections to all three boroughs, the island acts as a non-vehicular route for traveling between Manhattan, the Bronx, and Queens. Connection to the South Bronx Greenway is planned, with additional waterfront pathway sections, a naturalized "living shoreline," and further environmental restoration. Greenway segments are part of the East Coast Greenway, a 3,000 mile long trail system connecting Maine to Florida. A renovated golf center opened in 2008. The new $500,000 renovation has a two-tier indoor/outdoor, 82-stall driving range, of landing area, a 36-hole mini-golf course, grass tees, a short game area with sand bunker, PGA instructors, and 9 batting cages. Then, a tennis center opened in Randalls Island Park in July 2009. It features 20 courts, 10 har-tru and 10 rubberized hard (5 indoor), along with a cafe, pro shop, fitness facilities and locker rooms. From May–October, 10 courts are reserved for NYC Parks Tennis Permit holders during the daylight hours. In the winter, all 15 outdoor courts are bubbled for use by club members. The center is also the home to the John McEnroe Tennis Academy and was home to the New York Sportimes of World TeamTennis until the team relocated to San Diego in 2014. Finally, in May 2010, RIPA and the New York City Department of Parks and Recreation completed the construction of over 60 athletic fields to support a greater variety of sports, including football, lacrosse, field hockey, and rugby among the sports already played at the Park, soccer, baseball and softball. Randalls Island Park has the most athletic fields of any single New York City park. Three natural environments, two saltmarsh and a freshwater wetland, have been established on the island. Through the process of excavating over of debris, installing clean sand, and planting native marsh grasses,
