On your snack break, you may be accompanied by a friendly Siberian jay that has come to look for breadcrumbs. Listen to the knocking of a great spotted woodpecker, the slurping sound of a brambling and the melancholic "kwee-kow" call of a black-throated diver.

Some snowmobile tracks run in the northern and northwestern part of the national park. On the eastern side of the national park, a snowmobile track runs by the park and from there, there is a connection to the visitor centre's parking area.

Use of the snowmobile tracks requires a track permit. Information on the required permits is available on www.eräluvat.fi. Snowmobiling outside the track is forbidden. In some cases, Metsähallitus may grant a separate permit for snowmobiling outside the tracks.

The clear waters of Hossa are ideal for diving. The almost 40-m-deep kettle-hole pond of Öllöri is particularly popular with divers. There is a diving centre at the Karhunkainalo Camping Ground on the shore of Öllöri Pond. The diving centre provides a great setting for sports divers. Elsewhere, a permit is required for scuba diving.

• There are changing facilities, a space for servicing and drying scuba diving equipment, a place for filling diving cylinders (the customer's compressor), a jetty and a toilet.
• The closest places for filling diving cylinders are at the Kuusamo, Taivalkoski and Hyrynsalmi fire brigades.

You can have a spa holiday on the shallow beaches of the crystal-clear lakes of Hossa. Many ponds and lakes have sandy areas that are suitable for swimming. You will find good beaches at Lake Hypäsjärvi, Iikoski, as well as at Öllöri Pond, Karhunkainalo Camping Ground. Both of them have changing rooms. There are also sandy beaches at Kokalmus and Seipiniemi. There are no restrictions on swimming. You'll swim in the lakes and ponds of the national park at your own risk.

You can pick healthy delicacies on the heaths and mires of the national park, as you may freely pick berries and edible mushrooms. The amount of berries varies, but every year, pickers get at least some berries. The amount of mushrooms is more difficult to forecast.
