Id been toRuby Falls, an underground 145-foot waterfall, before on many childhood field trips.

I also got a text from the concierge service asking if I needed anything.

It was a bit chilly for me, but I could see myself spending hours there during warmer months.

Climbing the stairs, I found the wraparound porch, the perfect spot to take in the sunset.

Heres my review of theTreetop Hideaways at Ruby Falls.

Down the ladder is the living area, which has a leather couch that converts into a bed.

The kitchen sink is a converted washtub, and the cabin has plants scattered throughout.

A closet has bathrobes and umbrellas for guest use.

The bathroom is hidden behind a sliding salvaged door, with a shower and egg-shaped toilet.

The sink is made from a converted statue and the basin is also made from reclaimed materials.

Outside is the soaking tub, with curtains for privacy.

Ruby Falls has a small cafe, but for anything more substantial, youll have to venture out.

Thankfully, the historic St. Elmo neighborhood at the foot of the mountain has plenty of options.

Theres also a picnic set if you want to take it with you hiking.

The house has card games and a record player.

Treetop Hideaways also has optional add-ons like massages, laundry services, and alcohol delivery from a local shop.

The attraction also has a zip line course.

Above ground,Rock Cityis another longtime attraction on Lookout Mountain, open since 1932.

It started as a private garden that took on a German fairytale theme.

Today, it still has a nostalgic appeal, with rock formations and handmade dioramas of Mother Gooses Village.

TheIncline Railwayis another cant-miss nearby attraction, a funicular that travels at a steep incline up the mountain.

The car has plenty of windows for taking in the view as you ride.

Theres also a handicap parking spot in the lot.

The repurposing of items, like quilts for curtains and old barn doors, is another sustainability effort.

It straddles the Tennessee and Georgia state lines.
