These days almost all available methods for buying bitcoins also offer the sale option.
The exception is bitcoin ATMs: some allow you to exchange bitcoins for cash, but not all. Coinatmradar will guide you to the bitcoin ATMs in your area.
All exchanges allow you to sell and buy. Which type of swap you choose to sell your bitcoin will depend on the type of its owner: small investor, institution owner or dealer?
Some platforms, such as GDAX and Gemini, are more focused on large orders from institutional investors and traders.
Retail customers can sell bitcoins in exchanges such as Coinbase, Kraken, Bitstamp, Poloniex, etc. Each exchange has a different interface and some offer related services such as secure storage. Some require verified recognition for all functions, while others are more relaxed in the case of small quantities.
(Of course, do not forget to declare any benefit you will get from selling to the respective tax authority!)
You can, if you like, change your bitcoin for other cryptoassets instead of cash. Some exchanges, like ShapeShift, focus on this service, allowing you to exchange between bitcoin and ether, litecoin, XRP, dash and much more.
Another alternative is direct sales. You can register as a salesperson on platforms such as LocalBitcoins, BitQuick, Bittylicious and BitBargain and interested parties will contact you if they like their price. Transactions typically take place via deposits or transfers to your bank account after which you are expected to transfer the agreed bitcoin quantity to that address.
Or, you can sell directly to your friends and family once you have created a bitcoin wallet. Just send the bitcoin, you collect the payment in cash or mobile, and you have a drink for celebration together. (Note: It's usually not a good idea to meet strangers to exchange Bitcoin with cash.)
