Understanding Reserve California

It provides a convenient platform for visitors to plan their outdoor adventures and make reservations well in advance, ensuring a seamless experience for all.

Modifying Reservations on Reserve California

Reserve California understands that plans can change, and sometimes modifications to existing reservations are necessary. The process of modifying reservations can vary based on the type of reservation you’ve made.

Types of Reservations

Reserve California offers two primary types of reservations: campground reservations and tour/activity reservations. Each type follows a distinct process for modification.

Modifying Process for Campground Reservations

For campground reservations, Reserve California allows users to modify their bookings before the scheduled arrival date. You can adjust the dates of your stay, change the campground within the same park (if available), or even extend your reservation, subject to availability.

To make modifications, log in to your Reserve California account and navigate to the “My Reservations” section. Select the reservation you wish to modify and click on the “Modify” option. Follow the prompts to adjust your booking as needed.

Modifying Process for Tour and Activity Reservations

Tour and activity reservations on Reserve California can also be modified, but the process may vary depending on the specific tour or activity provider. Some activities might allow direct modifications through your account, while others may require you to get in touch with the provider directly.
