Voyagers is a coffeeshop located on the Geldersekade in the Red Light District, close to the Central Station of Amsterdam and is licensed to sell cannabis. Besides a coffeeshop where you can buy cannabis it's also a small hotel.
In both 2012 and 2013 they won an award for best coffeeshop. Besides their cannabis you can also enjoy space cake over here, and if you're staying in the hotel enjoy the smoker-friendly policy.
*Currently the coffeeshop-hotel is under construction, but they are still open every day!
