This was the most fun I've had on a Rodelbahn ever. I've been to quite a lot of Rodelbahnen in Switzerland where I live. This one here was beyond anything I've experienced. You can go REALLY fast without any problems. I went with my 4 and 6 year old girls (one at a time) and they were loving it as well, kept wanting me to go faster till on the last run I wasn't allowed to use the breaks (only at the end and one really steep drop), which was hilarious.
The staff was also very friendly. All together a super pleasant experience, a lot of fun. It's quite pricey, but it's definitely the longest run I've ever done. Go in the morning, there's WAY less people then. We didn't have to wait at all. When we wanted to go down at 5pm (when everything closes) we waited till past 6pm to ride down. They wait for everyone to ride down before closing which is really nice.
This is a tourist trap, we were passing by in the afternoon in high season, I just saw the coaster and thought that would be a cool thing to do for a quick stop... Well, in this place it seems there are no such things as a >quick< stop! We bought the tickets which I already thought were a bit expensive for a coaster, but once we arrived at the top we saw that there were at least 100, maybe even a 150 people waiting in line! We queued up for just 5 minutes but the line didn't even move, so I was looking at the frequency that they were sending off the carts and estimated that we would have to wait at least an hour, maybe 2 for it to be our turn... So we took the lift back down again, what a waste of money! We were never informed about the crazy waiting times at the ticket office... At least the view was okay.
Bergwelt is a fun place to take the whole family. There's a huge playground for the little kids, and an alpine sled ride as well as zip lines for bigger kids (and parents). You can get food and drinks at a few different locations (one much higher up the mountain, requiring a hike), and the views are gorgeous all around. Truly gorgeous.
You can hike up from road level, if you like (and have the extra hour+), or you can take a scenic ski chair lift ride up, which is what we did.
After you are all done, you can walk down and get some really great ice cream at the bottom. The "honey melon" gelato was to die for, and totally changed my view on fruit flavored gelatos. The chocolate was great, too. Yum.
We spent an excellent day here, and I really hope to get back next time we visit the Allgäu.
