Helvetinjärvi is located in Ruovesi. -a 50 square kilometer area in the Pirkanmaa region, near the Seitseminen National Park. You can see both parks in the same day. Facts which makes this park an attraction: The park has deep crevices in its bedrock, narrow opening that resembles a gorge (EU, Canyon U.S.), plus, there are forest ponds and small and lakes with sudden drop-offs. The Helvetinkolu Gorge, which is located northeast of Lake Iso Helvetinjärvi, is what is most attractive, since it's opening is only a few meters wide. The gorge has a steep downward slope into the lakeside. Here is a 10 minute video in Finnish of a tour through the Helvetinkolu gorge.
North of the Helvetinkolu gorge, is another fault formation. Lakes Kovero, Luomajärvi, Iso Helvetinjärvi: large Hell's lake Pikku Helvetinjärvi: small hell's lake and Pitkä Helvetinjärvi: long hell's lake, form a narrow, with high cliffs in the deepest fault, with high points 190 - 200 meters above sea-level.
What is there to see: Helvetinkolu and Haukanhieta.

Trip Tip: In southern Finland there are deer fly or yellow fly hirvikärpänen, which can bite you. Plan a trip to the more southern national parks later in the season, like in September, when deer fly are less rampant.
In September, as nighttime comes earlier, fewer visitors frequent the parks. When you sit around an outdoor fire, it is easy to sense that "around the campfire" atmosphere. You find yourself surrounded by dark woods.
