If you want to stay away from the pollution in the city, head over to Clearlake. It is known as the largest natural freshwater lake in California and one of the oldest lakes on the continent. The area rarely experiences coastal or valley fog, which is an indication of less pollution. In fact, you’ll get to experience a lot of sunshine, roughly about 265 days! Because of the relaxing weather, there are different activities that you can do such as hiking, biking, and off-road adventures. There are also some lakes perfect for fishing and kayaking.
