We took cog wheel train from Montreux up to the summit of Rochers de Naye at 2054m, which is a small ski resort in winter and a tourist destination in summer, as well as a station for the usual hiking and mountain biking.
The top is a little spoilt by being a ski resort with the lifts sitting idle, and the yurts in which people can stay overnight in summer. Not to mention the marmot enclosures. Though they meant that I now have actually seen a real life marmot, rather than just pictures and toys. Unfortunately, the alpine garden wasn't open yet, so I can't say the same for edelweiss.
We were a little unfortunate about the weather, as it changed a lot during the day. At the summit, it was windy and cloudy, though it would clear up for the magnificent view towards the lake to be seen.
In the other direction, we were able to catch glimpses of snow covered peaks, but were never able to see them.
After lunch, we started our slow descent down. I say slow, not because we were slow, but because of the frequent photo stops. The trail was quite pretty, with glimpses of the lake, and the valley towards Valais here and there, as well as the view back up the mountain.
It took us most of the afternoon to come back to civilisation, where we decided that the further effort to get back to Montreux wasn't worth the pain, since the path had become fairly steep and we were surrounded by buildings, and took the cog wheel train the rest of the way down from Glion, which had a very nice view of Chillon, the castle which I visited last year on the edge of the lake.
