The hike up Cerro de la Gloria in General San Martin Park is a steep 45-minute trek but worth the panoramic city views. Make sure you bring lots of water and go early in the day before the weather is too hot and the views too hazy. At the top, you’ll also be rewarded with an impressive bronze monument honoring the Army of the Andes led by Argentina liberator General San Martin, a battalion he marched from Mendoza to Chile to free the country from Spanish rule. The memorial was built to commemorate the Argentina Centennial of 1910. If you’re too tired to climb back down, you can take the public bus, but will need exact change to ride (check current price at the tourist office).
