We hired bikes - not clearly signposted at the railway station, where to hire from. You need to buy your coupons first & then go to collect your bike from elsewhere. We caught a paddle boat which dropped us off the 2nd stop. We cycled 32k around the lane. By no means the entire lake. The views were spectacular. Wiggis is beautiful.
We stopped for lunch at hotel Park Weggis. Too expensive to stay, but recommend a visit for lunch.
