The highlight of our trip to the Bruce Peninsula was descending into The Grotto. This beautiful partly under water cave is on the east edge of the Bruce Peninsula, between Marr lake and the boulder beach, near Cyprus Lake National Park. The trails to it wind along the edge of the Niagara Escarepement, through ancient cedar forests and by crystal clear lakes. It is stunning to look at, and exhilarating to explore. We visited the grotto last year as a family, but for all sorts of reasons didn't think it was the right time to climb inside. This year, the boys and I made the trek and it was well worth it. The look on the boys' faces when we made it to the bottom was priceless - such a great combination of awe, pride, and adrenalin rush. We stayed and played for a few hours, checking out the cave, swimming in the cool blue water, watching the 'older kids' jump off of the rocks, and trying to coach others down the rock face. I am sure that it was an afternoon none of us will forget.
