Memorial County Park is a useful choice when your group wants forest scenery and a picnic or overnight stay. Start with the official visitor page, then choose the actual facilities and walking route you need. Treat swimming as a separate question, not an automatic part of a campground booking.
The county trail page warns that some older maps and descriptions may be incorrect while the trail system information is updated. Start with the current park and campsite maps and ask staff about the route you intend to walk. For an interpretive forest outing, the county directs visitors to Park Headquarters for a Tan Oak Nature Trail handbook. That walking option is not a verified creek entrance.
Check admission, posted closing time and current trail notices before traveling. A campsite reservation does not confirm a creek entrance. The map point should not be used as a precise water-access destination, and the old swimming-hole-sign directions have not been verified.
The county's dog-site reservation notice explains the designated Huckleberry Flat option. Ask staff which routes your dog can use. Do not extend that exception to other camping areas or the creek.
The selected photos show redwood scenery and park features. They can help you decide whether a forest visit suits your group, but they do not identify a sanctioned swimming spot or demonstrate today's creek conditions.
Choose an authorized walk or picnic as your main activity until staff confirm any proposed water recreation. Read the park regulations, pack out rubbish and leave plants and fallen wood undisturbed.
Use the official park address, 9500 Pescadero Creek Road, Loma Mar, California 94021. Confirm current road conditions and designated parking. The retained coordinate is not verified as a water entrance; the historical swimming-hole-sign approach is not an approved arrival route.
Day use begins at 8 a.m. and ends at the posted closing time before sunset. Check trail and park alerts before departure. Dog camping does not establish dog access to Pescadero Creek.
Confirm the entrance, parking arrangements, and legal access with the land manager. A map pin does not establish a public right of access. Follow posted routes and never block gates or driveways.
County visitor information does not establish a designated swimming area or approved creek entrance. Confirm water recreation with park staff. Do not infer swimming permission from camping access. Public park access does not necessarily include permission to swim. Respect private property and posted restrictions.
Water conditions can change quickly. This listing does not provide a current safety or water-quality assessment. Check official alerts and avoid entering water when conditions or permission are uncertain.
Nearby places from saved public map data, not necessarily facilities at the swimming spot. Confirm access, hours, fees, and amenities with the operator before you drive.
