Along the same lines I would recommend Aconcagua. It isn't really touristy, it is a trail hike for all intense and purposes as it is not at all technical.
It's about 3,500 feet higher though which is a fair bit when you get into that range. I'm not sure I would say "not at all technical." Depending on the current conditions there could be snow and ice (and may be easier if there is).
