Mountain Lake Park has four tennis courts located at the 11th Avenue entrance. The courts are generally busy from early in the morning to late in the afternoon, with beginning, intermediate and advanced players. (They do not have lights.) Some players have regular weekly games, and intermediate players especially should have no problem showing up on the courts and picking up a game. The courts are surrounded by several different types of mature trees, which both make it a beautiful setting for the sport and also protect the courts from the wind.
Like all tennis courts in the City (other than in Golden Gate Park), play is on a first-come, first-served basis. According to City rules, which are posted on the fence, players must relinquish a court when someone is waiting if they have played a full set or have rallied for 30 minutes for singles or 45 minutes for doubles. It is not uncommon for players to invite people waiting to join their match. Also, players must choose a court to wait on.
Tennis players are encouraged to remember to throw away their trash, especially dangerous lids from tennis ball cans.
