"California's colossal redwood trees are impressive enough, but add a carpet of colorful wildflowers beneath them and it's serious scenery overload. Redwood National Park's wildflower blooms emerge between January and September. That means, for the majority of the year, you can appreciate the eye-popping colors. Spring welcomes blooms like periwinkle forget-me-nots and golden mission bells, while California poppies and western dog violets last into late summer and fall. Some of the best wildflower hikes include the Trillium Falls, Lady Bird Johnson Grove, and Redwood Creek trails." - Travel + Leisure Editors
