Lake El Estero is a citywide park in central Monterey. Originally a salt-water lagoon, its outlets to the bay were cut off because of over flooding. The 24.7-acre (100,000 m2) park has become an estuary to many migrating birds and ongoing improvements have been made into preserving the park. Lake El Estero offers several activities with its baseball diamond, skatepark, and the world famous Dennis the Menace Park. Many parks and attractions have been developed in Lake El Estero to attract both tourists and locals. The most popular of these is the Dennis the Menace Playground.
