The Lake of Annecy, surrounded by mountains is amazing at all seasons, you can enjoy it by boat, bike or car. For a full Annecy Lake Tour with a car, I will recommend you to start from Sévrier (as the traffic Sévrier/Annecy can be quite bad sometimes) there you could visit the bell museum https://musee-paccard.com/, go through St. Jorioz, a quick stop in the center of Duingt (a little walk to the castle, privately owned) then maybe a swim or lunch in Doussard. You can also walk to the Réserve Naturelle du Bout du lac, lovely hike by the lake.
Then if you are lucky and there are no clouds, drive up to Col de la Forclaz (Montmin) which is 1157 meters high, it is about 20 minutes drive from Talloires but the view is fantastic! It is famous for paragliding lovers! You can walk up hill for 15 minutes to reach the paragliders departure place which is a lovely spot to take photos or have a picnic.
Finally, you can make your way back to Annecy going through Menthon St Bernard and Veyrier du Lac (maybe stop to see the Castle of Menthon, the best spot to take a photo is to take the road going to Alex on the right when arriving in Veyrier).
Please book in advance if you need a taxi/driver from Annecy to do the Annecy Lake Tour https://www.taxi-massingy.com/
