Emerging Dark Sky state park John Martin Reservoir State Park

Colorado Parks and Wildlife

Colorado Parks and Wildlife lists John Martin Reservoir State Park as open daily from 5am to 10pm.^[1]

CPW says its two campgrounds are open year-round. Lake Hasty Campground has 109 sites below the dam with electric hookups, while Point Campground has 104 basic sites on the north shore of the reservoir. Reservations are required.^[1]

What that means for stargazing

The direct CPW source does not market John Martin as a dedicated astronomy venue. For this guide, Point Campground remains the most useful field-verification target because it combines legal overnight access with the open reservoir setting. That is a guide inference from the campground layout, not a CPW stargazing recommendation.^[1]
