Both nature- and city-lovers agree that Crandon Park is a great place to paddle. Not only do you get the best views of the city but you can also lose yourself in Key Biscayne's ecosystems. Whether you choose to venture under the Rickenbacker Causeway or take a tour through the mangroves, you won't be disappointed. Experienced riders can brave the choppier seas of the south and catch a glimpse of the Cape Florida Lighthouse. Prices aren't bad: $20 for a one-hour rental and $45 for three hours. If you want to get your ashtanga on, find your inner Zen with stand-up paddle yoga. Private kite-boarding lessons are also available. This is truly an adventurer's playground.
