ReserveAmerica availability rules

ReserveAmerica is the booking platform behind many state park reservation sites. Each state agency writes its own rulebook. The sites run on one platform and follow different policies. This page documents three states whose agencies publish their rules in detail. For any other state, find the same items on that agency's site.

The same platform, three rulebooks

"Not stated" means the agency page checked for this reference does not give the rule. It does not mean the rule is absent.

Indiana

Indiana's Department of Natural Resources publishes the most complete rule set of the three.

Window

• Campsites open a maximum of six months before the arrival date. On March 1, September 1 arrivals become available.
• Online inventory opens at noon Eastern, the hour the reservation phone line opens, so that web and phone customers start together.
• In months without 31 days the window rolls forward. August 29, 30 and 31 arrivals cannot be booked until March 1. In a leap year, August 29 opens on February 29.
• A reservation can run up to 13 nights past the window edge, within the 14-night maximum.

The 18-day freeze

A reservation whose departure date is beyond the maximum booking window cannot be changed or cancelled for 18 days from the date it was made. Transfers and cancellations are allowed from day 19.

Minimum stays

Three published exceptions open single weekend nights:

• One-night relaxed rule. A campsite not rented within three days of arrival becomes available for a one-night stay. Holiday minimums are excluded.
• Gap rule. If two reservations leave a lone Friday or Saturday between them, that night can be booked by itself. Not on holiday weekends.
• Seven nights or more. A stay of seven or more nights has no weekend restriction.

Same-day reservations

Since April 30, 2025, Indiana campsites can be reserved until 11 p.m. Eastern on the arrival date, online or by phone. The rules state that properties do not hold back campsites for walk-ins. Rally camps and youth tent areas are outside the 11 p.m. rule.

Cancellation and change

The $6 transaction fee charged on each new reservation is not refunded. Web cancellations close at 11:59 p.m. Eastern the night before arrival. Partial cancellations are not allowed: the whole reservation is cancelled or none of it. A reservation can be transferred to another site or date up to the day before arrival. A date change on or after the arrival day requires cancelling and rebooking.

Pennsylvania

Pennsylvania's Department of Conservation and Natural Resources states that most state park campsites can be reserved from 11 months in advance up to noon on the day of arrival.

Under an 11-month window, a July weekend can be reserved the previous August.

Oregon

Oregon State Parks changed its same-day rule on January 1, 2024. Before that date online booking needed 24 hours' notice.

Oregon gives the staffing needed to hand out keys and codes as the reason for the earlier cabin and yurt cutoff. Some Oregon campgrounds also keep first-come, first-served sites, seasonally or year-round.

Finding the rules for another state

Each state's ReserveAmerica site links to that agency's reservation policy. The items worth locating are the ones in the comparison table: window length, release time, month-end handling, weekend and holiday minimums, the same-day cutoff, and any freeze on new reservations. The Indiana document shows how much these can affect what a calendar displays, and none of it can be assumed to carry over to a neighbouring state.
