We had an afternoon for a quick hike, so I suggested South Pack Monadnock to see if the lady slippers were blooming.
A few years ago, we hiked South Pack and found gobs of lady slippers along the Marion Davis trail. This year, I had just planted some lady slippers in my yard that were starting to bloom, so I thought we might see if they were out on South Pack.
It turned out we were a little early. Some of the lady slippers were not in full bloom yet. In exchange, the trillium were still blooming.
The Miller State park site has a good map of the trails.
