If you want to give your credit card some exercise, head out to Larcomar Shopping Center in Miraflores. Hotels.com travelers also say the area is artsy and has lots of nice beaches. It's also full of great shops and restaurants, so you can spend the afternoon having a wander. Splash some more cash at Larco Avenue, Paso 28 de Julio, and Calle José Gálvez.
Whether you want to hunt for sand dollars or smell the fresh air, Waikiki Beach is a spot you might want to check out, located 4.6 mi (7.4 km) from central Lima. If you want to continue walking by the waves, head to Makaha Beach and La Pampilla Beach, both within a short walk.
