Oahu has more than 60 beach parks, including the large Ala Moana, just west of Waikiki. Beach parks are popular with Oahu families. During weekends at Ala Moana, many people arrive at the break of dawn to reserve some of the more popular spots. Large extended families spend the entire day at the park, cooking, and playing games. Kapiolani Park, home to the city's zoo, also is a popular park. A large section is dedicated to sports fields, including soccer, rugby and softball. There is plenty of hiking in the nearby mountains, with trails that lead to waterfalls and gorgeous views of Honolulu. Diamond Head, an extinct volcano, offers one of the most popular walks in the city.
