Redwood City's park system has nine parks with reservable picnic areas bookable online year-round — no seasonal blackout, no fixed rental windows. Stafford Park's shaded picnic area with a playground and tot lot is under a mile from downtown; Red Morton Park has a sheltered picnic area alongside Magical Bridge Playground, one of the Peninsula's most beloved inclusive playgrounds. The city's ActiveNet portal handles all bookings, and a permit is required for any gathering of 25 or more. We pulled together the five best parks for a birthday party within 4 miles of central Redwood City.

For Redwood City birthday parties where coverage and a great playground both matter, Red Morton Park delivers. Redwood City's sheltered picnic area sits next to Magical Bridge Playground, the fully accessible inclusive play structure that's become a Peninsula landmark.

Good to know: sheltered picnic area, playground, restrooms, BBQ grills, basketball courts, baseball diamond, bocce court, tennis courts, soccer field, Magical Bridge Playground adjacent, pool adjacent.

Parent tip: Magical Bridge Playground is a public facility open to all — you can't reserve it exclusively, but booking the sheltered picnic area right next to it gives your party the best seat in the house. The playground was designed for kids of all abilities, which makes it an especially strong choice for birthday parties with guests who have accessibility needs.

3. Marlin Park (Redwood City)

Location: 509 Cringle Dr, Redwood City, CA 94065

Redwood City👶 Best for all ages💲 Free🚗 3.2 mi

Pavilion: Picnic Area 1 + Bounce House Area  ·  Capacity: Holds up to 100 people  ·  Amenities: bounce house area designated, BBQ grill on site, playground adjacent, tot lot adjacent, restrooms on site

Confirm bounce house contractor rules when booking.

Good to know: picnic area, playground, restrooms, BBQ grills, baseball diamond, basketball courts, pickleball courts, soccer field, tennis court, tot lot, bounce house area.

Parent tip: Marlin Park is the Redwood Shores neighborhood park — if your birthday guests are coming from the Redwood Shores side of the city, this is closer and more convenient than Stafford or Red Morton. The designated bounce house zone is the park's biggest advantage; verify current bounce house contractor requirements when booking.

4. Stulsaft Park (Redwood City)

Stulsaft Park delivers a natural-woods birthday party feel that Redwood City's other parks can't replicate. The playground is nestled among trees in a 42-acre park with BBQ pits, hiking trails, dog-friendly areas, and natural canopy shade. If your kids are into nature or you want a wooded backdrop for party photos, Stulsaft is the only pick in the city that looks the part. 100+ capacity, restrooms, year-round ActiveNet booking.

Good to know: picnic area, playground, restrooms, BBQ grills, hiking trails, dog park, tot lot.

Parent tip: Stulsaft's natural setting is particularly appealing for woodland- or nature-themed birthday parties. The hiking trails adjacent to the picnic area give adventurous kids somewhere to explore between cake and presents, and the park's mature tree cover makes it cooler than open-field parks on hot summer days.

5. Dolphin Park (Redwood City)

Reserve Dolphin Park pavilion → Pricing on reservation page · year-round; groups 25+ need permit

Redwood Shores families' local birthday park — Dolphin Park, playground adjacent, BBQ grills, restrooms on site. Dolphin Park is the residential neighborhood option in Redwood Shores with a reservable picnic area, playground adjacent, BBQ grills, and restrooms. Low-traffic, neighborhood feel makes for easy supervision. Year-round ActiveNet booking, permit required for 25+ guests. For bounce house parties in the same area, Marlin Park is nearby.

Good to know: picnic area, playground, restrooms, BBQ grills.

Parent tip: Dolphin Park is the neighborhood option for Redwood Shores families who want to keep the party close to home. Marlin Park is a mile further north in the same area and offers a designated bounce house zone if you're planning inflatables — but for a simpler setup without bouncers, Dolphin works well.

Frequently asked questions

How do I reserve a picnic area in Redwood City?
All nine Redwood City picnic parks book through the city's ActiveNet portal — the link under each park above takes you there. Create an account with your email, select the park and picnic area, choose your date, and pay online. You'll receive a confirmation with your permit. A permit is required for groups of 25 or more.

Can I just use a picnic area without a permit for a small birthday party?
For groups under 25 people, no permit is required and picnic tables are first-come, first-served. For anything over 25 (typical for most kid birthday parties), a permit locks in the area and ensures no one else can claim the space.

Does the picnic area reservation include the playground?
No — playgrounds, including Magical Bridge at Red Morton, stay open to the public during your rental. Your permit covers the designated picnic tables only. Other kids will be on the equipment, which is fine for most birthday setups.

Are bounce houses or inflatables allowed at Redwood City parks?
Redwood City's general picnic rules do not permit inflatables. Contact Parks and Recreation at (650) 780-7311 to confirm the policy for your specific park and date before booking entertainment.

Heads-up: rental fees, capacity limits, and rules around bounce houses, alcohol, and amplified music vary city by city and shift every season. Always click through to the official Parks & Rec page linked under each park before you send invites — it's the only source guaranteed to be current.
