Foster City is built around a lagoon — and that waterfront DNA runs through its park system, with parks along the Bay levee, a sailboat-tied boardwalk at Leo Ryan, and easy access to San Mateo County's Coyote Point just a few miles away. Within 20 miles, families also reach Palo Alto's exceptional inclusive playgrounds and wooded natural preserves. We mapped the best parks within 20 miles of Foster City.
1. Leo J. Ryan Memorial Park (Foster City)
Location: 650 Shell Blvd, Foster City, CA 94404
Foster City👶 Best for all ages💲 Free🚗 0.6 mi
Boardwalk, boats, and a summer concert lawn. Leo Ryan is Foster City's community anchor — 20 lagoon acres with a wooden boardwalk, kayak/paddleboard rentals, basketball and tennis, and an amphitheater where the summer concert series runs free. Kids who've outgrown playground equipment find the lagoon activities and bike paths genuinely engaging. The waterfront setting makes any visit feel more like an outing than a park stop.
Good to know: boardwalk, lagoon access, kayak rentals, basketball, tennis, bike paths, amphitheater, restrooms, picnic areas.
Parent tip: Paddle and pedal boat rentals (California Windsurfing) operate seasonally — check the Foster City Parks page for 2026 rental hours. Summer evening concerts are free and fill the park; arrive early for good lawn space. The boardwalk is stroller-friendly and a great evening walk.

2. Coyote Point Recreation Area (San Mateo)
Location: 1701 Coyote Point Dr, San Mateo, CA 94401
The full-day Bay park that Foster City families drive to most: Coyote Point's Magic Mountain Playground — 42-foot castle, eleven slides, separate 2–5 and 5–12 zones — is one of the best play structures in San Mateo County. Add a sand beach, no-license Bay fishing breakwater, CuriOdyssey wildlife museum, pump track, and weekend train rides in one $6–7 vehicle entry.

Driving from Foster City, about 17 min without traffic gets you there — easy to pair with a lunch stop in Palo Alto.

The Bay Area's best family nature walk — tidal marsh, Duck Pond, and 15 miles of trail: Baylands Nature Preserve is a 1,940-acre tidal marsh at the edge of San Francisco Bay, with 15 miles of trails, the Lucy Evans Nature Interpretive Center, a Duck Pond, and docent-led programs.

Parent tip: The Lucy Evans Nature Interpretive Center (free) has interactive exhibits and a viewing deck over the marsh — good stop before or after the trail walk.
