Rideau Woodland Ramble
I am no green thumb but one of the most attractive places we visited while at Merrickville was the Rideau Woodland Ramble. Visit their website if you want to know some more.
This is part 2 of some of the beautiful things I saw at the gardens. (They were closing for the season - but it still was a delightful visit).
If you have a garden and a library, you have everything you need.
