You will learn about the nature and history of the inner and outer archipelago on the three nature trails of the national park. Sturdy, comfortable footwear is recommended for hiking on the nature trail. During rain the trails can be very slippery.

• Älgö Nature Trail (2 km) focuses on the islands closer to the mainland and leads you through hilly terrain to the fishermans home of Rödjan and an observation tower with glorious views over the sea.
• Modermagan Nature Trail (1.8 km) introduces you to the flora and fauna of the outlying islands and takes you past an old splinter-proof shelter and dugout.
• Jussarö Nature Trail (4.0 km) or the shorter nature trail (2,8 km) takes you past old mine shafts and into ancient woodland, a rare sight along the coast. There is also an observation tower en route. Summertime you can climb the controll tower of the coast guard to admire the open and beautiful seaview.
