Kakumäe beach is not as well known as Pirita beach and is therefore less crowded, which is to say, you might have the beach to yourself, like I did when I went! The beach has relaxed atmosphere since most of the people there live in the local neighborhood, so it has quite a community feel to it. The beach has everything you would expect – hot sand, cool water. Due to its exposure the beach can be quite windy, however this is great for those wanting to practice their windsurfing and kite-surfing skills, who says Estonia doesn’t do extreme sports!? Board and kite hire is available from the little surf shack on the beach. 
You need to take bus 21A/21B/41B to Sooranna tee stop, and walk along Sooranna tee street until you get to the beach, its not far. You could also bike from Tallinn. Once you get out of the city center, there are quite good bike roads all the way to Kakumäe beach. The round trip is around around 24km. 
United’s Top Tip: Head to the top of the Kakumäe peninsula really great views of limestone cliffs.
