Kuikan Kierros Nature Trail (6,5 km) leads through varying landscape up and down ridges. It is so beautiful that the atmosphere is almost fairy tale-like. The trail should be travelled clockwise. It is marked with yellow circles. At first the trail goes around Kokkolahti Bay, after which visitors may walk 2 km along a narrow ridge to Korkeasärkkä and back. Otherwise after Kokkolahti Bay the trail leads to the ridge between Lakes Savulampi and Syväjärvi and on towards the River Tuomipuro. The trail crosses paths with Taitajan taival Trail at Lake Ruunulampi. From there the nature trail continues towards Lake Pieni Joutenjärvi. Visitors walk through spruce mires along duckboards and emerge into Mustalampi mire. After crossing the road the trail leads downwards to the clear waters of Lake Kuikkalampi, where visitors can spot beavers' burrows. From there the trail rises up onto the ridge again. On the eastside of this ridge there is a fen meadow, where local people used to harvest hay for their livestock for winter. The rest of the trail leads across spruce heath, where visitors can see signs of forest fires past on the trees. Hikers should reserve two to three hours to see this trail.

Boating and Canoeing Routes
There are no marked routes in Petkeljärvi National Park, but a waterway which flows into the near-by River Koitajoki is good for boating and canoeing. In 2003 Petkeljärvi National Park hosted the Finnish National wilderness kayaking championship event.
The River Koitajoki, which is over 200 km long, is known as a good canoeing destination. The river flows partially east of the border in Russia and empties into Lake Nuorajärvi northwest of the National Park. It is also possible to canoe from Lake Petkeljärvi to Lake Koitere in Patvinsuo National Park. The distance between these two lakes is 80 km. Another possibility is to canoe from Lake Petkeljävi 20 km southward to Mutalahti Bay.
