Worth knowing

Trails rated limited: the page names only Mosca Pass Trail and Dunes Overlook Trail, but pets are permitted throughout the Preserve, so more trails than the two named may be open there.
Backcountry is mixed on this page: prohibited in the dunefield backcountry beyond the first high ridge and in park backpacking campsites, permitted in the Preserve; recorded as unknown.
The phrase 'Off of the Dunes Overlook Trail' appears in the list of places pets are not permitted; its exact meaning (probably staying on the trail there) is not explained.
Page warns fines up to $5000 and/or 6 months in jail for violating the pet regulations.
Page shows a 'BARK Ranger Rules' poster but does not say the park runs a B.A.R.K. Ranger program, so barkRanger is null.
Page does not mention kennels.

How we read the rules

Every statement on this page was taken from the park’s own pets page on nps.gov and the quoted sentences are re-checked against our saved copy of that page each time the site is built. Parks change pet rules for wildlife, heat and trail conditions, and superintendents can close areas at short notice, so treat the park’s pets page and the ranger at the entrance as the final word. Service animals are covered by different rules. Compare all 63 parks.
