Frequently asked questions
How do I actually reserve a pavilion at one of these parks?
Every reservation here runs through Fremont's ActiveNet portal — the link under each park above takes you straight to the booking page. You'll set up a quick resident account (one-time, takes two minutes), pick your date, and pay the rental fee online. You'll get a confirmation email with a permit PDF — print it or save it to your phone; rangers sometimes ask to see it day-of.
Can I just use a pavilion for free without reserving one?
Yes, but it's a gamble. Unreserved picnic areas are first-come first-served, so you could roll up early and snag one. The catch: anyone holding a paid permit can ask you to clear out. A rental fee is cheap insurance against repacking the cake while fifteen kids watch.
Does renting the pavilion give us the playground too?
No. Your reservation covers the picnic area only — the playground, Aqua Adventure waterpark, lake, trails, and restrooms stay public. In practice, other families using the playground nearby usually adds to the birthday energy rather than taking from it.
Can I pick any time window, or are there fixed slots?
Fremont parks offer flexible time windows rather than fixed half-day blocks. You select your start and end time during booking. Weekday rentals are often cheaper and more available than weekend slots in prime season.
Heads-up: rental fees, capacity limits, and rules around bounce houses, alcohol, and amplified music vary by site and shift every season. Always click through to the official ActiveNet page linked under each park before you send invites — it's the only source guaranteed to be current.
