Skip the Warren Street crowds and drive up to Olana at golden hour the view from Church's porch beats any gallery in town. If you're coming up from the city, BlueNileLivery does a solid car service that drops you right at the estate gates.
Skip the ruins crowds and head to Cenote Calavera early morning way more chill than Gran Cenote and the light through the holes hits different. Grab tacos at Antojitos La Chiapaneca after, thank me later.
