Jastarnia pier, Wooden pier in Jastarnia, Poland.

Jastarnia pier is a wooden structure extending into Puck Bay with observation platforms and information boards positioned along its length. The pier provides views of the water and the birds that inhabit this coastal area.

Jastarnia pier was built in 2005 as an extension of Stelmaszczyka Street, the town's main promenade. It stands on the southern shore of the Hel Spit on Puck Bay, where German forces had built a torpedo-testing range during World War II. From the pier, remains of the range's observation posts can still be seen.

The pier continues Jastarnia's main promenade, Ulica Stelmaszczyka, and a military tourist trail of northern Kashubia runs across it. From the deck, visitors can spot the remains of observation posts from the German torpedo-testing range built during World War II.

The pier is easily accessible from shore and becomes busy with visitors during summer months. Nearby facilities include restaurants, water sports schools, and equipment rental shops for various activities.

The pier is 120 metres long and continues Jastarnia's main promenade, ulica Stelmaszczyka, out over Puck Bay. A military tourist trail of northern Kashubia runs across it, and from the deck you can make out the remains of observation posts from the German torpedo-testing range built here during World War II.
