Hello mitahalim, and welcome to our forum!
There are two options you can consider: the Swiss Half Fare Card, allowing you to buy 50% discount for all trips in Switzerland, and the 3 day Swiss Travel Pass. This one's more convenient, as all regular train trips are fully covered and you won't have to buy additional tickets. This goes for the boat trip over Lake Brienz as well. You'll only have to buy discounted ticket for mountain visits, like the Jungfraujoch. If you want to compare both passes price wise, please follow the instructions at our page on picking the right pass.
Both passes are valid up to the Swiss/Italian border (depending on your connection, the exact train station will most probably be Domdossola), so you'll need a ticket Domodossola-Milan too.
Please note that the Brienzer Rothorn Bahn usually opens in mid-May, so if you'll be visiting in the first week, you'd probably have to skip this. Mürren-Grütschalp may very well be open, but this can't be predicted yet. You'd best consult the local tourist office once you're there. If it's not accessible, the Lauterbrunnen-Stechelberg hike down at the valley floor is a great scenic alternative.
I hope this helps you out!
