The Campsite Tonight app helps campers secure last-minute campsites at popular national and state parks that are often booked months in advance. The app scans availability and sends alerts when spots open up, allowing users to quickly reserve the sites through the Recreation.gov platform.

Why it matters

Many national and state park campsites are booked solid months in advance, leaving little opportunity for spontaneous or last-minute trips. The Campsite Tonight app aims to solve this problem by tracking cancellations and notifying users when openings become available, making it easier for people to enjoy the outdoors on short notice.

The details

The Campsite Tonight app, created by programmer Mike Lee, scans availability at over 50 campgrounds across 11 states, including popular destinations like California, Arizona, and Florida. When the app detects a canceled reservation, it can automatically reserve the spot and hold it for the user for up to 15 minutes, making it easy to finalize the booking. The app is particularly useful for securing campsites during peak seasons or events when demand is high.

  • The Campsite Tonight app was launched in 2026.
