Redwood National Park

This massive natural reservation, located on the scenic coastline of Northern California, consists of nearly 140,000 acres of stunning redwood rainforest. It's a must-visit spot for nature lovers who enjoy camping, fishing, and hiking. There are multiple trails to explore the park's many wonders, from its majestic sequoias and towering Douglas firs to the stunning Lady Bird Johnson Grove. You might even spot wildlife like the majestic Roosevelt elk and the colorful banana slug. The best time to visit is in summer—make sure to pack layers as it can get chilly. Admission to the park is free, but the three state parks within the park charge a day-use fee. – Tripadvisor
