Region · 31 park units · 5 states
Alaska's largest wilderness parks, Hawaii's active volcanoes, and the Pacific island monuments. The most logistically demanding parks in the system — and the most rewarding.
This region contains 31 distinct National Park Service units spread across 5 states and territories. The list below covers the full spectrum of designations — from flagship national parks down to the smallest national historic sites — because for travelers planning real trips, all of them count. A National Historic Site may not have the visitor numbers of Yosemite, but for a weekend route it can be the more interesting stop.
If you're new to the region, the most efficient way to plan is to pick two or three parks within driving distance of one another and build the trip around their seasonal sweet spots. A spring trip through the Southeast looks completely different from a fall trip through the same parks; a summer week in the Pacific Northwest is a different experience from a shoulder-season trip in October. Each park guide on this site flags the specific months when conditions are ideal.
Across the parks listed below, the practical realities you'll encounter are remarkably consistent. Entrance fees range from free (most historic sites and battlefields) to $35 per vehicle for the marquee parks, with the $80 annual America the Beautiful pass paying for itself by the third paid park. Reservations for in-park campgrounds open on a rolling schedule on Recreation.gov — generally six months in advance for peak-season slots, which sell out within minutes of the release window for the most popular parks. Backcountry permits are separate, often free or $10–$20, and have their own lotteries.
Visitor centers across the region open by 8 or 9am and close between 4:30 and 6pm depending on season — useful to know if you're planning a long driving day. Cell coverage inside park boundaries is unreliable in the rural parks and reasonable in most front-country areas; download offline maps before you leave the gateway towns. Water at trailheads is available at the developed parks but assume backcountry water needs to be filtered.

If you'd rather narrow by state, every state with parks in this region has its own dedicated index — typically grouping all designations (national park, monument, seashore, historic site, etc.) onto one page.
The single most useful piece of advice for travelers planning a trip in this region: build in slack. Park visits almost always run longer than expected — an hour at a visitor center turns into three; a "quick scenic drive" eats half a day. The travelers who leave a park system genuinely satisfied are the ones who let themselves be surprised by it. If you've planned three parks in five days, plan two parks in five days instead. The region rewards depth over breadth.
