Why go to Edinburgh?
The sea that skirts the north of Edinburgh, the Firth of Forth, is a pleasant place to try sea kayaking for the first time. Travel into the city centre from the airport by bus of taxi. You can then easily get down to the coast in Leith by the number 22 bus from Prince's Street. Guided trips and kayak rental are available (www.duneideannseakayaking.com) for your kayak outing. The nature of the equipment (and safety considerations) means that this isn't really a plan you can just turn up and do yourself.
