This route was planned by komoot.
This specific komoot route, named the Hidden Forest and Arnold Ice Cave Trail, is considered easy. It is approximately 1.2 kilometers (0.75 miles) long and takes about 19 minutes to complete, with minimal elevation gain.
Yes, given its short distance, easy difficulty, and minimal elevation gain, this route is well-suited for beginners and families looking for a quick and accessible outdoor experience.
The trail traverses ponderosa pine forests and features interesting lava outcroppings. While the komoot route is short, the broader area of the Arnold Ice Cave Trail often has a narrow tread with bunchgrass, sagebrush, and hidden rocks, including some rocky sections.
The primary highlight of the area is the Arnold Ice Cave, a lava tube system known for its year-round ice formations, including frozen stalagmites. The surrounding landscape also includes ponderosa pine forests and lava outcroppings.
Clear days in spring and early summer offer excellent views of the snow-capped Cascades. However, the Arnold Ice Cave itself maintains year-round ice, making it an interesting feature in any season, though access might vary with snow cover in winter.
Specific parking details for this exact komoot route are not provided, but trails in the Deschutes National Forest typically have designated parking areas near trailheads. It's advisable to check local forest service maps or signs upon arrival for the most accurate parking information.
Regulations for dogs in the Deschutes National Forest generally permit leashed dogs on trails. However, specific rules can vary, especially near sensitive areas like caves. Always keep your dog on a leash and practice Leave No Trace principles.

It's best to check the official Deschutes National Forest website for current requirements before your visit, especially if you plan to park at a developed trailhead.
Yes, this route utilizes sections of several official trails. It follows parts of the Swamp Wells Road, the National Forest Development Road 1800-300, and the Arnold Ice Cave Trail Number 63.
Even for a short, easy hike, it's wise to bring water, appropriate footwear for potentially rocky or uneven terrain, and layers of clothing. If you plan to explore the ice cave, a headlamp or flashlight is essential, and a jacket is recommended due to the cold temperatures inside.
Yes, the area around Arnold Ice Cave is part of a larger lava tube system. Other nearby lava caves include Charcoal Cave and Boyd Cave, which were formed when the roofs of underground lava tubes collapsed. These caves were historically used to harvest ice and are known to have ancient Native American artifacts.
