The best view in town is free! Take the elevator up to the 72m-high (240-ft.) lookout, and Brasilia is laid out at your feet. You'll get the best perspective of the Eixo Monumental with the ministry buildings lining the boulevard like dominoes waiting to be knocked over. Time your visit toward day end to take in the city with a fiery red Brasilia sunset. You can skip the gem museum without qualms.
