Hallenbad Allmend

This is state-of-the-art facility has an incredible view of snow-covered Mt. Pilatus through a floor-to-ceiling glass wall on the deck.
Like many other European facilities, Hallenbad Allmend does not share "community" swim equipment as is done in most places in the US - you need to bring your own.
Be careful on exiting the locker room, the cleaning lady will chide you if you wear shoes in a section that is off limits to street shoes - but there is no sign :)

I just got back from Luzern and swam here. It is crowded, two to four people per wide lane, but you get to swim in a new, clean, indoor pool. The whole pool is dedicated to lap swimming - just pick a lane that looks like it's your speed and hop in. I made the mistake of swimming in the very slow lane (it was empty when I got in) and the other swimmers kicked me out and into another lane. LOL!
Great facility - lockers, showers, large lukewarm Jacuzzi®, and cafeteria.
My hotel gave me a discount booklet that included a small discount into the pool.
Bus 20 from the rail station drops you off next to the building.

When I went, it was too crowded; the entire pool was set up with circle swimming in the lanes. A real nightmare.
