Never miss a permit deadline again
May 2025
Hey all,
Most advanced lotteries have passed, but it’s not too late if you couldn’t secure a permit. Many parks release last-minute permits a few days before your desired start date.
If you can’t wait until the last minute, you can create Outdoor Status alerts to get notified when we find canceled permits.
New Zealand reservations are opening up for the 2025–2026 season

If you’re an outdoor lover, New Zealand has everything you need. The Great Walks are New Zealand’s premier trials, and ideal for a first trip to the islands. Just as in North America, reservations are required and go out quickly so it’s necessary to book early. The 2025–2026 season opens next month at 9:30am New Zealand Time on the following dates:
- 15 May: Heaphy Track, Kepler Track, Rakiura Track
- 22 May: Whanganui Journey, Routeburn Track, Tongariro Northern Circuit
- 27 May: Lake Waikaremoana Track, Abel Tasman Coast Track, Paparoa Track
- 28 May: Milford Track
Guide to the Grand Canyon’s Rim-to-Rim hike

The Grand Canyon Rim-to-Rim hike is one of my favorite backpacking trips in the US. But planning that trip is challenging because it’s a point-to-point hike, the hiking season is short, and permits are limited.
Now is the best time to plan that trip because September’s lottery is open and October’s one opens on May 16. Check out the interactive guide.
