To get into the garden, you must make a reservation. The purpose of this becomes obvious when we saw that there were only two parking stalls. This, as you can imagine, translates to a wonderfully intimate experience where you can lose yourself in nature.
Once you arrive, you have 50 minutes to enjoy the waterfall, carp lake, a small pool, and an open air shack before the next set of visitors arrive. There was construction going on last week across the street which somewhat disturbed the peacefulness of this place, but otherwise it was a great place to meditate. Be sure to book your reservation at least a week in advance.
