Seenalper Seeli is a hidden alpine lake located between kanton Schwy and kanton Uri.
You need to take the cable car from Brügg up to Biel Kinzig. From the cable car station you will be hiking 500 meters up towards the summit Chinzig Chulm. From here you continue your way down towards Seenalperseeli. Take a dip and have a picnic before you resume your hike towards Muotathal. It is a long and steep descent, all together 1580 meters.
The hike is 14,2 km long with 590 meters of elevation gain.
In case you left your car at the cable car station, don't hike towards Muotathal, but from the Seenalper Seeli lake hike back the same way you came down.
Super beautiful spot, and you won't find many people.
