We had a pleasant morning hike, capped off with a light snack at the Lake Agnes tea house. This is a medium difficulty hike. We did see a few people with 'normal' shoes or even sandals but you'll enjoy it more if you have sturdy sneakers or light hiking boots. It can get a little crowded so you to well to get there early.
The tea-house had just opened for the season so the staff were still getting sorted out but they were friendly and doing their best to cope on a busy day.
