Craters Of the Moon/Lava Flow

Overview

Lava Flow Campground offers a truly otherworldly experience situated directly within the Craters of the Moon National Monument and Preserve. Unlike standard roadside stops, this campground provides a rare opportunity to sleep amidst a vast ocean of lava flows and cinder cones. The park is typically open from May through November, weather permitting, and operates on a first-come, first-served basis. Staying here allows travelers to witness the stark, beautiful contrast of Idaho’s volcanic history under a sprawling sky.

Location & Surroundings

Positioned just off Highway 20/26/93 near Arco, Idaho, the campground is set at an elevation of nearly 5,900 feet. The surroundings are defined by cracked basalt landscapes and resilient high-desert vegetation. Because the park is situated far from major urban centers, the air is incredibly clear, and the horizon is dominated by the Pioneer Mountains to the north. It is a remote setting that feels disconnected from the modern world, offering a quiet, reflective atmosphere for those traversing the Snake River Plain.

Amenities & Park Features

This is a dry camping facility, meaning there are no hookups available. The park provides several basic essentials for visitors:

• 42 paved sites with charcoal grills and picnic tables
• Centrally located flush toilets and seasonal potable water
• Access to designated International Dark Sky viewing areas

The campground does not have a dump station or showers. RVers should note that most pads are relatively short; the park is best suited for smaller rigs and camper vans, as sites rarely accommodate units over 35 feet.

Nearby Attractions & Things to Do

The primary draw is the seven-mile Loop Road, which provides easy access to the monument’s most iconic features. Visitors can hike to the summit of Inferno Cone for panoramic views or explore the various lava tubes and caves, provided they obtain a permit. The nearby town of Arco offers a touch of history as the first city in the world lit by atomic power. Additionally, the park is a designated International Dark Sky Park, making it a premier destination for stargazing and night photography.

Who This Park Is Best For

Lava Flow Campground is ideal for adventurous travelers who prioritize unique scenery over luxury amenities. It is a perfect fit for astrophotographers and hikers looking to explore geological wonders right from their doorstep. Because of the size limitations and lack of hookups, it is best for those in smaller motorhomes or travel trailers who are prepared for boondocking-style camping. If you value silence, dramatic sunsets, and a sense of isolation, this volcanic retreat is a must-visit destination.
