National Parks in Indiana

What This State Directory Includes

This page uses complete NPS state membership. A trail, parkway, river, historic route, or other distributed unit may appear in more than one state. Not every listing is formally designated a National Park, so the designation is shown separately for each site instead of treating every NPS unit as the same park type.

Core park identity and state membership come from locally stored NPS-derived records. Individual park pages provide current bundled NPS visitor information and explain reference-coordinate limitations.

Sites with a National Park Designation

These NPD listings carry a National Park, National Park & Preserve, or National and State Parks designation in the current source record. Some NPS records group related named parks, so this is a directory-record view rather than a claim about the official count of separately designated parks.

Map of NPS Sites in Indiana

The markers use NPS reference coordinates. A reference point may be an administrative or geographic point rather than an entrance, trailhead, visitor center, or nearest access point—especially for trails, rivers, parkways, and other distributed units.

Multi-State and Distributed NPS Sites

1 listings associated with Indiana also belong to at least one other state or territory. Their state membership is shown below so a single-state label does not imply the whole unit is located only here.

City Guides in Indiana

These are NPD city-based park discovery pages. They compare NPS sites by straight-line distance from each city; they do not claim that a park is located inside the city or that the distance is road mileage.

Source and Freshness

Park identity, designation, complete state membership, images, and reference coordinates are derived from NPD's locally stored National Park Service data. NPD city relationships come from the dedicated city directory and are kept separate from NPS park addresses.
