Cycling around Lagoa is a great option when the weather or your head is cloudy.

Get breakfast at a juice bar: Açaí with a ham&cheese sandwich (misto).
Rent a bike for the whole day (R$35) at
BikeTech Av. Bartolomeu Mitre, 455 2239-3600 or 21583340Make sure you rent the lock too, as you will be leaving them locked here and there.
Head over to Lagoa and cycle around it anti-clockwise, stopping at any of the coconut stands for some coconut water.
Once three quarters of the way around it, you should look for signs of the Jardim Botânico. Get over there, lock the bikes and walk around for half an hour.
Then bike over to Parque Lage, right next door. Nice. Snoop’s “Beautiful” video was taped there.
Then get back out and go for lunch at the Gavea mall’s food court. After lunch, check out the rest of Gavea Mall.
