Quito is definitely worth a visit if passing through on your way to some of the world class highlights of Ecuador, like Island hoping through the main Galapagos Islands, 3 days / 2 nights hiking the Quilatoa Loop or Climbing to the summit of Cotopaxi Volcano, and especially if you need a few days to aclimatise to the altitude.
But, if I’m being honest, I wasn’t blown away by it and I think part of it had to do with not feeling 100% safe when wandering around the city centre.
You’ll naturally wandering through the Old Town and check out some of the cool restaurants. Also make sure though that you take the cable car to Volcan Pichincha to see the city spread out amongst the mountains – the highlight for us.
