When you walk around in Aschau, you'll see some nice painted and old houses. For example near the church you’ll find the former "Hotel Post" which is a noble hotel & restaurant now (I've looked at the prices – crazy!). Also at the main street there are several nice houses – just walk around and take a look!
There's a 120 km long hiking trail which connects Tyrol (Austria) and Bavaria (Germany) and passes Aschau and Sachrang. It's well signposted and we walked parts of it near the Schossrinn waterfall. It there goes along the river Priem and we had not problems with the prams.
You can purchase a hiking guide (German or English) or a hiking map for this hiking trail at the tourist information in Aschau. More information on the stages also can be found on the webpage.
The Schlossrinn waterfall is nice little waterfall which is about 20 m high and is found near Schossrinn (not really a village, there are only a few houses). It's not far from the main street Aschau – Sachang and the "Grenzenlos" hiking trail, but unfortunately the last part of the trail is not suitable for prams or wheel-chairs. It's a small path through the forest, and there's a little gate that you should close after you passed it.
There is another waterfall which is closer to Aschau, it's called Floderer Waterfall and is located at Einfang.
The Bärnsee is a litte lake in a swamp area. There's a nice hiking trail around the lake, but as the lake and its direct surroundings are a nature protection area, you cannot get really close to it. As there's swamp, there had been some wooden catwalks, but unfortunately they were not always long enough. As it had rained the days before, the trail sometimes was really sludgy! The trial went up and down, not so easy with prams, but still possible. We finally went up to Höhenberg, a little village from which you have a nice view on Aschau.
The Kampenwand is a 1670 m high mountain next to Aschau, with a small ski area and several hiking trails. There's a cable car from Aschau up to the top, each cabin offers seats for 4 persons. The cable car starts near the castle, it's signposted with "Kampenwandbahn".
More information like schedule and admission can be found on the webpage.
The castle is found on a 690m high hill and dates from the 12th century. It was reconstructed several times and today it's own by the state and used as recreational center.
Parts of the castle can be visited with a guided tour. Unfortunately it was not open when we had been in Aschau.
