Going to Warairarepano, formerly known as Teleferico, is an amazing experience even for those who have a fear of heights. The 20 min ride up is amazing, I recomend doing that with daylight and ride back down at night so you can appreciate the lights of the city. At the top you'll find various restaurants and kiosks with food and souvenirs, and a walkway leading to the grand hotel Humbolt which is closed for renovations, unfortunately . There is also an ice skating rink, but sometimes it is closed, a matter of luck I guess. It makes cold at night so bring a jacket if you plan on haging out there for a while. On the whole, it's a nice place to spend a little time with family.
