On the edge of the Lagoa Rodrigo de Freitas, across a busy road, this park and sculptural garden has a short but steep trail to the Mirante do Sacopã lookout, which offers memorable views from a height of 130m above Lagoa. It's a 15-minute walk along a 600m forest-lined path. For a bit more excitement, you can scale a rock-climbing wall, go rappelling (abseiling) or take a treetop walk offered by Lagoa Aventuras.
