It’s no surprise that at 470 feet, the GeO-Deck at Reunion Tower is Dallas’ highest public observation point (to get higher, make reservations at either of the restaurants above it). Still, if you’re looking for a lesser-known viewing location, give the Sky Lobby in Chase Tower a visit. Located on the 40th floor, the floor-to-ceiling glass walls on the east and west sides overlooking downtown make for a perfectly Ferris Bueller-esque moment. Bonus: this one’s free. 2200 Ross Ave. 214-777-5300.
