12 Things I Learned on My First Visit to Yellowstone National Park

Yellowstone National Park is one of the most remarkable destinations in the world. With over 2.2 million acres of untouched wilderness, geothermal wonders, and diverse wildlife, it’s no surprise that nearly 4.5 million people visited the park in 2023 alone. For a first-timer like me, it was both breathtaking and overwhelming. 

I dove in headfirst, eager to explore its wonders, but along the way, I also stumbled on lessons that will prove invaluable for anyone planning their first trip. Here’s what I learned and what you should know before heading to Yellowstone. 

Plan and Book Early 

Yellowstone’s popularity means accommodations fill up fast—sometimes months in advance, so reserve early. For campgrounds inside the park, bookings through Recreation.gov open six months in advance, while lodges can be booked as far out as 13 months. If you’re late to the game, some first-come-first-serve campsites release spots just two weeks before the trip, but your chances are slim. 

Insider tip: Indian Creek Campground, near Mammoth, is often the last to fill. However, the National Park Service has announced that it will be closed for the 2025 season due to overnight closures required for ongoing infrastructure upgrades.

The Park is Massive

To grasp Yellowstone’s scale, consider this: at 3,472 square miles, the park is larger than the entire state of Rhode Island and Delaware combined. 

Plan your itinerary strategically. Divide your trip into regions—e.g., focus on the geothermal features near Old Faithful one day and wildlife-rich Lamar Valley the next. This will prevent you from spending too much time driving between areas. 

Wildlife Viewing is Best at Dawn and Dusk

Yellowstone is home to incredible wildlife—grizzly bears, wolves, bison, elk, and much more. But if you want to catch them in action, timing is everything. The best times for wildlife spotting are early morning (just after sunrise) or evening before dusk. Lamar Valley and Hayden Valley are particularly famous for their sightings. 

On my trip, I saw a herd of elk grazing in Lamar Valley at sunrise—a serene and unforgettable moment. 

Pro tip: Carry binoculars for distant sightings and check with visitor centers for recent updates on wildlife activity. 

Respect Wildlife Safety Guidelines

Yellowstone’s wildlife may be captivating but also wild and unpredictable. The National Park Service says maintaining a safe distance is essential—at least 25 yards from most wildlife and 100 yards from bears and wolves. Too many accidents occur because visitors try to get too close for the perfect photo. 

When hiking in the backcountry, bear spray is a must. It’s available for purchase or rental at key locations, and rangers can teach you how to use it. Safety doesn’t just protect you—it protects the animals, too. 

Stay on Designated Paths and Boardwalks

Yellowstone’s geothermal areas, like Grand Prismatic Spring and Norris Geyser Basin, are jaw-dropping and dangerous. The thin crust over boiling pools can collapse underfoot, tragically claiming lives in the past. 

The National Park Service (NPS) warns that hot spring water can cause severe or fatal burns, as scalding water often lies beneath the fragile, breakable crust surrounding these springs. To make matters more dangerous, the terrain around these thermal areas shifts constantly, making it nearly impossible to identify a safe off-trail path. Stick to marked trails and boardwalks for your safety and the health of the fragile ecosystem. 

Be Prepared for All Weather

Yellowstone’s weather is famously unpredictable, from snow flurries in July to sweltering heat in August. During my trip in early June, I encountered sun, rain, and hail—all on the same day! 

Pack layers, a waterproof jacket, and comfortable hiking boots, regardless of the season. It’s better to over-prepare than to be caught shivering at an overlook. 

Cell Service and WiFi are Limited

Yellowstone is a digital detox paradise—you won’t find reliable cell service in most areas. Connectivity is sparse and limited to major hubs like Mammoth, Old Faithful, and Canyon Village. 

Download offline maps and any important trip details beforehand. And don’t forget a paper map—it’ll come in handy. 

Visit Popular Sites Early or Late

Crowds are one of Yellowstone’s few downsides. Iconic sites like Old Faithful, Grand Prismatic Spring, and the Grand Canyon of Yellowstone can feel packed during peak hours. 

To beat the crowds, visit early in the morning or later in the evening when tour groups and families have thinned out. I arrived at Old Faithful at 7 AM and had an excellent view of the eruption without the bustling crowd. 

Take Advantage of Park Resources

Yellowstone’s visitor centers are treasure troves of helpful information. For example, the Old Faithful visitor center posts predicted geyser eruption times, while Mammoth’s Albright Visitor Center shares the latest wildlife sighting reports. The free National Park Service app is also a fantastic tool. 

Drive Responsibly

Yellowstone’s roads are narrow and winding, so driving responsibly is imperative. Use designated pullouts for wildlife viewing or photos, and never stop in the middle of the road—especially during a “bison jam.” Ranger-led traffic control exists for a reason: stay patient and enjoy the moment. 

Bring Plenty of Water

Hydration is key, especially if you’re hiking at higher elevations. Bring reusable water bottles (at least two liters per person for day hikes). Many visitor centers have refill stations, so take advantage of them to stay refreshed. 

Allow Enough Time

Attempting to see all of Yellowstone in one or two days is a recipe for exhaustion. With its vast terrain, geothermal marvels, and wildlife-rich valleys, Yellowstone deserves at least four to five days to appreciate its offerings truly. If you’re short on time, focus on one or two regions rather than cramming in everything. 

Yellowstone National Park is a bucket-list destination for a reason. It offers moments that will stay with you long after your trip. Following these tips and planning, your first visit to Yellowstone can be remembered for all the right reasons.
