From the top of the funicular you can walk around the lake/reservoir, climb up the a mountain hut at 2412m, or walk back down to Handeck.
The funicular operates from early June to mid October. It costs 15 Swiss francs [CHF] for a single ticket and 25 CHF for a return.
On the other side of the valley road from the funicular base station there is a large hotel and car parking. You can cross the road from the car park by the new Handeck Bridge. This is only 70m long compared to the 167m of the Trift Bridge.
