Hello k4karen, welcome to MySwissAlps!
I think you've come up with a good itinerary. It covers some of the prettiest regions in Switzerland and is very varied in terms of hiking, city visits and scenic trips. Here are some thoughs:
- Montreux is generally considered prettier for tourists than Lausanne, so you may want to change your base for the first few days;
- on day 3, the Golden Pass would be a beautiful route towards Interlaken, rather than the regular train connection. It does take a bit longer though, so you should limit your stay in Geneva somewhat if you're interested in this ride;
- on day 5, it may be too early to for the Eiger Trail. The recommended period for this hike is July-October and by June, the trail may still be covered by snow. You'd best check with a local tourist office once you're there. Finding a hike at lower altitude as a back-up plan would be wise. Options are here;
- the same goes for the hike on day 6. You can contact Zermatt tourism to ask for current circumstances once you're there. Further hiking tips can be found here. Do leave early, as day trip to Zermatt from Interlaken will take quite some time, especially if you want to include the scenic local train via Kandersteg and Goppenstein instead of the quicker tunnel route. Details are in the timetable;
- as for day 7: I'm not sure about your hiking experience and condition, but do note that Lauterbrunnen-Wengen is quite steep. If you feel up to that, it's fine. If not, you may first enjoy the pleasant hike in the Lauterbrunnen valley and then get to Wengen by train.
Once your plans are set, you should look into rail passes. A 15 day Swiss Travel Pass would be the easiest option for your plans. You may compare this to the Swiss Half Fare Card, but bear in mind that this requires you to buy discounted tickets for each trip.
It's very hard to predict anything about the weather. June may be rainier than July and August, but there have been years with the exact opposite pattern, with beautiful spring/summer weather in June. Just make sure you have enough back-up plans in case weather doesn't allow for hiking.
