Before you go

A little preparation goes a long way.

  • Choose a route or play area before arriving; large parks can have several parking areas and entrances.
  • Check trail, restroom, playground, boat-rental, or splash-pad conditions only if those amenities are part of the plan.
  • Pack water, layers, and shoes that match the terrain rather than planning around tickets or timed entry.
