The popularity of hang gliding in Rio [1]—second only to surfing [2]—is unsurprising viewing the spectacular surroundings involved. The classic (and most breathtaking) trip is to jump off Pedra Bonita (in the Parque Nacional da Tijuca [3]) and glide down to the Praia do Pepino in São Conrado [4].
Both Just Fly (tel. 21/2268-0565, www.justfly.com.br [5]) and HiltonFlyRio (tel. 21/2278-3779, www.hiltonflyrio.com [6]) charge between R$240 and R$280 for the thrill, including transportation to and from your hotel.
