Recommend hitting the most challenging part of this trail upfront by heading uphill and counterclockwise. This provides your kids an offramp when you come to the intersection with Twin Creeks Trail, QT Marker 6, .9 miles into the trail. If you take on the entire trail, you will encounter a few hills as you make your way around the rest of the 1.1-mile loop.
If you plan on checking out the beach after, try and time it during a period where the tide is below 5 feet. During a super-low tide, parking will be difficult. Arrive early or be prepared to walk it in.
