Marumba is a rustic, eco-friendly retreat for nudists and those who appreciate a secluded natural setting. The main accommodation is a cabin constructed from recycled materials, featuring a ceiling fan, screened louvres, and solar power. A scenic, outdoor cooking area offers a two-burner gas stove and a 12v chest fridge. Situated on a rocky hilltop, access requires a climb of 99 steps; however, transportation is provided for arrivals and departures.

The cabin includes a queen bed, TV/DVD, storage, and a work desk. Shared amenities include a bathroom with a hot shower and flush toilet in a separate building, plus a BBQ area with outdoor seating, market umbrella, and an outdoor shower and toilet.

Spread across 140 acres of native bushland, Marumba offers walking and cycling trails across varied landscapes—rocky ridges, valleys, open grasslands, and seasonal billabongs—where guests are free to roam unclothed. Located 7 km from Adelaide River, essential services such as a general store, dining options, and a medical clinic are nearby. This quiet haven is ideal for a relaxing, back-to-nature experience, with wildlife sightings adding to the outback adventure.
