Lassen Park's Manzanita Lake is about as picturesque as they come, and its beauty is just the beginning. It's famous for its large rainbows and browns, and can be fished from the shore, float tube, or drift boat. Try to keep your eyes on your line, because the birds, deer, and mountain views will compete for your attention. Or hike the Manzanita Lake trail, and easy, mostly flat trail that wraps around the lake. Great for bidwatchers, wildflower enthusiasts, and families. You can pick up this loop trail from the boat launch area or behind the Loomis Museum. Check with park rangers for guidelines.
