I'm not even going to save the best for last. Secret Cove is hands down one of the most, if not the most photogenic spot in all of Tahoe. When the sun hits the cove just right it creates a brilliant turquoise color that you have to see to believe.
Located off Highway 28 on Tahoe’s East Shore, it's easily accessible via a short hike from the main road or from the Secret Harbor Parking Lot. Secret Cove is a clothing optional beach, and you will more than likely see a few of the local naturalists sunbathing on the granite rocks along the beach. Side note: Some of the locals are pretty protective of the beach as they've made it their personal mission to keep it looking pristine. As long as you are respectful of the beach rules as well as their privacy while taking photos you shouldn't have an issue.
Tip: Secret Cove is beautiful year round but it can get crowded during the summer months, especially on weekends. I find the best time to go is off season, during the week, and in the late morning when the sun hits the cove just right to get that turquoise color. The water is also calmer durning this time from lack of activity giving it a glass-like effect.
