@Becky those sound like good ideas might have to check some out.thx
My daughter loves the library, indoor playgrounds at the mall, she does ballet, we go on little trail walks and she loves to pick flowers and rocks. Some indoor activities we do are sensory bins, painting, turning off all the lights and having a glow stick dance party, turning on some Disney lofi while she independently plays, I also love to bake so she is always in the kitchen helping me.
My 2.5yo does Gymtots, ballet, swimming and rugbytots every week. Aside from that we do the park, play cafes, or soft play in winter.
