The location is indeed incorrect: after the dam, quickly turn left and follow the Muddus sign for 10 km, there is a parking lot at the end of the paved road. Nice place to stay if you want to go hiking in the Muddes nature reserve. The place itself is not that special, so it is a parking lot with a number of facilities (two waste bins and a dry toilet). Walking in the area with dogs not allowed (1/5-31/12).

The parking lot and starting point for hiking trails is beautifully landscaped. Dry toilet looks neat. The place indicated in the app definitely does not correspond to the correct place. From the dam, follow the sign for 10 km to Muddus nature reserve. Drive all the way to the end of the paved road, then you end up at the parking lot. Peace and nature are your part.
