Skyline to the Sea, Berry Creek Falls, Hammond Road Loop is a 11.1 mile moderately trafficked loop trail located near Riverside Grove, California that features a waterfall and is rated as moderate. The trail is primarily used for hiking, walking, nature trips, and birding and is accessible year-round.
Quite a nice trail with good variety in environment. There was a bridge out on the Timm Creek Trail which resulted in a slightly different route from what is shown here - make sure to stop by the office to check on the conditions of the trails. I don't think our modification (stayed on the Sunset trail to the falls) added any significant mileage. I do think that the distance listed here is a bit of an underestimate, I measured closer to 14 miles on the entire loop.
Great hike with several waterfalls through the stunning Great Basin redwoods. Going counterclockwise leads to a massive elevation increase near the end. Starts out low elevation near creeks in the redwood forest before going up on a ridge to descend down to the various waterfalls. After the waterfalls, a huge climb to the Mt. McAbee overlook with gorgeous views out to the Pacific. Redwoods, waterfalls, and banana slugs make for plenty of photo ops.
Going at a brisk pace with relatively frequent photo stops and a lunch break at Berry Creek Falls took us ~5 hours.
