The Lady Bird Johnson Grove is a relatively flat 1.5 mile walk through the redwoods. It is often considered the most popular hike in Redwood National Park, especially during the spring when the pink rhodendrons are blooming. Subsequently, when we were there, this was the most packed trail so we didn’t like it as much. This is an easy walk for a stroll, there is a small hill that you have to take to get to the actual trail, but otherwise is a relatively flat trail.
