I went with my dog on a Monday from Geneva for an afternoon. The weather was chilly but great for walking and exploring. I did not go inside the church but the area around it is amazing. Many different views of the old own, the lake below. Ramparts to look thru, narrow staircase to get up high to one part. Paths lead down to old town or to an open park area with an interesting foot bridge. We had the area to ourselves basically which made it more enjoyable. Plenty of benches to picnic at on a warmer day.
