Nice walk. In and out about 5 miles. Not much shade, not too many benches, but also not crowded. Pleasant for dogs as well, especially if you walk up to the end: dog beach in Del Mar.

Nice little walk with the family. Ages 3, 7, and 9.
No need for a stroller.
Good picture opportunities.

Over all lovely time.

Mostly flat trail which goes from Dog Beach in Del Mar and ends up at the east end of the polo fields (near Morgan Run Country Club) in Rancho Santa Fe. I park at the east end of the polo fields, walk the trail east, head to the beach, hike up the cliff at Dog Beach, and back.

From Dog Beach heading east, you will go past the river along the race track, cross Jimmy Durante Blvd, walk the "Boardwalk", along a trail under I-5, along a trail behind the old Albertsons, along an up and down trail to El Camino Real, cross into the Polo Fields, then back the same way for a 8 mile out and back trek

This is a nice flat walk ideal for young and old alike. Most of it is on a wood planked boardwalk and navigates over a protected wildlife wetland. It winds up to the 5 fwy underpass and then becomes the Pacific Crest Trail. You can continue on for a couple more miles but then the trail stops as it is currently incomplete.

Real nice walk. Bring a smart phone with a QR reader and you can read/listen to the interactive points along the way describing history and environmental facts. No elevation changes to speak of. It is better to start at the west end near the south gate of the Del Mar fairgrounds. Park across the bridge to the south. Try coming at different tide times to see different things.
