The ferries are ageing but pleasantly outfitted. Eurailpass holders travel for free, and it's easy to connect from the Rothorn (steam mountain) railway at Brienz. One can also visit Iseltwald (as we did) - apparently it's famous due to some South Korean series that meant nothing to me. Staff were unobtrusive with the ferry mostly on time throughout the journey. In late October, there was no crowding, although all the dining area was occupied with rich Europeans. The lake is attractive: not quite as stunning as say Sydney Harbour, but not pedestrian either.

Stunning day out. Beautiful lake - great for swimming and paddleboarding. From Interlaken you can take a lake cruise or a train to Lake Brienz. We took the cruise there and the train back. We found the cruise really packed and there is no queuing system so it's just a bundle to try to get a good seat when the boat arrives. It's a slow journey but there are some wonderful views on it. You can get off along the route to visit Geissbach Falls but then you would have an hour until the next boat so we didn't. We got the train back to Interlaken which was much quicker but you miss out on the scenery. We found a great place for swimming and paddleboarding called Strandbad. It was very basic and the English was limited but it was lovely and quiet. There were changing rooms, toilets, a cafe, an outdoor shower and sunbathing lawns. You could hire paddleboards by the hour too. It was about a 10 minute walk from the train station but absolutely worth it. 5 Franc entrance fee.

After we took the cruise trip to explore the Lake Thun, we came to Interlaken OST(see) to cruise over the Lake Brienz! We had Swiss Travel Passes so the fares were included within our Passes. Again, we had the privilege to sit upstairs which was a lot quiet and comfortable than sitting downstairs. It was quite empty so we managed to move around to the best seats to snap the best pictures alone the shores. The scenery was picturesque, although I have to say Lake Brienz is not as breathtaking as Lake Thun & the trip was relatively short (1 hr 13 mins), but it was still a 5 stars experience! The only downside was that I was punched by a German speaking guy on my chest unexpectedly, when I said yes to his friends to take a picture for the group of them on the ship. Don't really know why, (obviously he didn't like me) Fortunately it didn't ruin my day. Still, a 5-stars cruise which I will highly recommend it to everyone. p.s. Iseltwald is absolutely beautiful

Joined at Interlaken Ost in fine weather and had an enjoyable excursion. This is not cheap, even with half price ticket, so do choose a good day. Some vessels call at different locations so check timetables if not going to Brienz. We took the train back to town for views of the lake

We took a round trip boat ride from Interlaken to Brienz, and then back again to Interlaken. The lake is beautiful, and it’s a peaceful journey in both directions. The boat stopped at several places along the way, and there were hiking trails, train rides, restaurants and waterfalls to enjoy. But we just stayed on the boat, and had lunch in Brienz. The water is remarkably clean, and a stunning turquoise blue. It’s a great way to spend a relaxing day in Interlaken.

We took a one way cruise from Brienz to Interlaken and it was amazing experience because the lake is very beautiful - stunning turquoise water. There are some special places within this ride like seeing the Giessbach waterfalls fall into the lake or like looking at the Giessbach hotel and the rail track as the boat moves away from Giessbach. Such a calm and serene ride.

We visited the Interlaken. And of course we took the chance of spending time in Lake Breinz - the lake with the turquoise color. It is so clean. The view is breathtaking. The area is truly a treat for a "dolce far niente".

We did the Steamboat ferry from the train station to Giessbach Falls. The Lake had to be the most beautiful one I have ever seen. We had a perfect sunny day with a few clouds to make photos better.I wish we had time to get off in Iseltwald. Just didn't have time.
