Sandvika is situated approximately 15 kilometers (9.3 mi) west of Oslo. It is the main transportation hub for Western Bærum, and has a combined bus and railway station. Sandvika is also one of the stops along the route of the Airport Express Train. Sandvika also has Scandinavia's largest super mall, Sandvika Storsenter, with 190 stores and a total area of 60,000 square meters or 650,000 square feet. On 13 March 2013, the previously pedestrianized main street was opened for car traffic and on-street parking. Sandvika used to be home to the BI Norwegian Business School business school, which moved to new surroundings in Nydalen in August 2005. The building was, after some refurbishing, converted into the home of Sandvika High School.
The nearby island of Kalvøya is a place for recreation. The Boat Sport House is located on Kalvøya, and is used by Bærum KK and Bærum RK.
A small islet in Sandviksbukta, outside Sandvika, is called Danmark. Danes who live in the area join together every year on 5 June Denmark's national day to celebrate.
Claude Monet visited in early 1895. During his stay he painted several views of the town and the surrounding landscape, with the mountain ridge Kolsås featuring in many of the paintings either in the background or as the primary subject. Perhaps the most well known of the paintings from this visit is 'Sandviken Village in Snow' which features the Løkke bridge in the foreground with Kolsås in the background. The bridge still stands in Sandvika.
