Here are five American parks you’ll need to win a lottery to visit.

The odds of winning $1 on certain scratch tickets are just over 20 percent. The odds of winning a permit to certain national parks? Sometimes as low as four percent. You may want to break out your lucky charm if you want to visit any of these places:

Coyote Buttes North Lottery
The Wave is a surreal-looking natural sandstone rock formation that undulates across the desert landscape of Coyote Buttes. In order to protect this fragile formation, only 64 people are allowed to visit it each day, with 48 individual permits (and/or 12 group permits) being given away in advance in an online lottery and the remaining 16 individual permits (and/or 4 group permits) drawn during a daily lottery.
Applicants must pay a nonrefundable $9 fee each time they apply (and can only enter the lottery once each month) and can choose up to three potential visitation dates per month. The lottery is run four months ahead, so if you want to visit the Wave in May, apply in January. If you win, the permit cost is $7 per person, and you’ll receive a route map with photos of landmarks and GPS coordinates to help you find your way

Private Grand Canyon Rafting Trip Lottery
Want to raft down the Grand Canyon, but don’t want your experience ruined by a terrible guide or annoying tour groups? A lot of people apparently feel the same way, as permits for 12- to 25-day self-guided raft trips from Lees Ferry to Diamond Creek formerly had a 27-year waitlist. In 2006, the NPS decided that the insanely long waiting list would be replaced by a lottery.
This weighted lottery gives preference to those who were on the old waitlist, as well as The main lottery is held once a year during the first three weeks in February, and follow-up lotteries are held throughout the year to reassign spots from any canceled trips. There is a $25 fee to apply for the lottery and, for winners, a $200-$400 trip deposit, a $20 entrance fee, and a $90/person river permit.

Guided Bear Viewing at McNeil River State Game Sanctuary and Refuge
In the summer, up to 144 wild brown bears a day descend on McNeil River State Game Sanctuary and Refuge to fish for the thousands of salmon that swim past during their upstream migration. Can’t bear to miss that? Enter the lottery and you might be one of the lucky 10 people per day that are allowed to view the spectacle between June and August.
The program limits the number of people who may be present at McNeil River Falls (or the other viewing locations) to no more than 10 individuals, so as not to disturb the bears. If you win one of the 185 permits available, you’ll be allowed to camp at the campground, visit the sanctuary, and attend guided bear viewing sessions over a designated four-day period.

Half Dome Cables Lottery
A 14-mile hike seems tough enough to weed out most people, but not at Yosemite’s most famous attraction, Half Dome. Despite the fact this challenging hike involves scrambling up steep granite domes using steel cables and wooden planks as makeshift stairs to reach the summit, the hike attracts hundreds of visitors every year.
The steel cables are only up from late May to mid-October, and may be taken down early or put up late due to weather conditions. During this season, only 225 daily permits (225 for hikers and 75 for backpackers) are issued to summit Half Dome. The lottery runs March 1 through March 31, and you designate a specific date or range of dates you would like to climb. Feeling spontaneous? Around 50 permits are made through a daily lottery that you can enter two days before your chosen hiking date. You’ll pay $10 to enter the lottery and $10 for a permit if you’re successful.

Phantom Ranch Lottery
Located at the bottom of the Grand Canyon, Phantom Ranch is only accessible by hiking or riding a mule the approximately 7.5 miles down, or by rafting in via the Colorado River. The ranch recently changed its reservation system to a lottery system. (Note: Occasionally, a few beds will open up due to cancellation.) The lottery is held monthly between the 1st and 25th and runs 15 months ahead (so entries made in January 2024 would be for reservations in March 2025). Unlike the other lotteries, this one is free to enter.

Twist’s Take: You’ll be lucky to visit these five American parks; only lottery winners can enter!
