1. Oslofjord is a scenic inlet in southeastern Norway, stretching from the city of Oslo to the open sea. It is known for its stunning natural beauty, with calm waters, rugged cliffs, and small islands scattered throughout. The fjord offers many recreational activities such as swimming, boating, and fishing. The surrounding area is also rich in flora and fauna, making it a popular destination for nature enthusiasts.

One interesting fact about Oslofjord is that it was formed during the last Ice Age, as large glaciers carved out the landscape and created the deep, narrow inlet. The fjord is approximately 100 kilometers long, with its widest point being around 10 kilometers. It is also home to several historic sites, including fortresses and lighthouses that have played important roles in Norway’s maritime history.

2. Oslofjord does not have specific working hours as it is a natural landscape that can be visited at any time. However, certain attractions and activities within the area may have their own operating hours. It is advisable to check the individual websites or contact the specific attractions or tour operators for their opening times.

3. There is no specific ticket required to visit Oslofjord itself, as it is a natural landscape freely accessible to the public. However, if you wish to take a ferry or boat tour to explore the fjord or visit nearby islands, there may be ticket fees. Prices and ticket information can be obtained from the respective ferry or boat companies operating in the area. Public transportation options such as buses and trains also connect Oslo to the surrounding areas of Oslofjord. Information on these transportation options can be obtained from the official websites or by calling the transportation authorities in Oslo.
