Get the Most Out of Your Visit

Frequently asked questions about the Inflatable Playground:

  1. Do I need to know how to swim to use the inflatable playground?

    Yes, you should have basic swimming skills. The majority of play equipment is in water more than 4 feet deep. All users are required to wear a life vest included with admission.

  2. Are lifeguards on duty?

    Yes, multiple lifeguards watch visitors from shore, and lifeguards on paddle boards are stationed inside the play area.

  3. Can older children visit the playground unsupervised?

    Children 14 and younger require at least one parent or chaperone to be at the swimming lagoon at all times, and parents need to sign a waiver for all children in their care. Teens 15 and older can sign their own waivers. Read the safety rules and required waiver (PDF: 2.42 MB).

  4. If a parent does not want to play on the inflatables, does the parent need to pay admission?

    The adult will not need to pay, but will need to stay outside of the inflatable playground.

  5. How many people can be on the inflatable playground?

    We can accommodate up to 80 visitors at a time. Once we reach capacity, we rotate visitors through the play area in 45-minute sessions. Weekends and holidays can be busy. To get the most time on the equipment, plan on arriving when the play area opens at 11 a.m. or visit on weekdays when attendance is lighter.

  6. Why is a wristband required?

    Color-coded, disposable wristbands help us quickly see who has paid admission.

  7. How clean is the water?

    Water in the spring-fed swimming lagoon is chlorinated and circulated throughout the swim season. The Sonoma County Department of Health Services regularly monitors water quality, and samples consistently exceed health and safety standards.

  8. Can people with physical limitations access the inflatable playground?

    We make every effort to assist visitors with physical limitations. Accommodations can be made on a case-by-case basis and may include the use of a beach wheelchair to reach the water. For more information, please speak with parks staff or call Regional Parks' aquatics manager at (707) 565-2824 Monday through Friday.

  9. Can I reserve the inflatable playground for parties or special events?

    Yes, you can rent the playground from 10 to 11 a.m. for $350 for up to 50 people, with guests then enjoying all-day access during regular public hours. Rental includes the use of a group picnic area. (Additional private party guests are $10 per person.)

  10. Are floats permitted?

    For safety reasons, personal swim gear is not allowed in the inflatable playground.

  11. Can I bring my dog?

    Dogs are welcome at Spring Lake Park but are not allowed on the beach or in the lagoon. If you bring your dog, it will need to stay on the grassy areas.
