Venture from Hopkins into Actun Tunichil Muknal — Belize’s ceremonial underworld — where river crossings, tight passages, and preserved Maya offerings culminate at the crystallized remains known as the Crystal Maiden. This day trip blends jungle hiking with guided cave exploration and strict site preservation.
More ways to explore the area's outdoor wonders
You step off the trail where the jungle hush is interrupted by a river that dares you across its shoulders. Guides fit helmets and headlamps with brisk efficiency; the air smells of wet limestone and loam. A thirty-minute walk through forest gives way to a narrow hourglass entrance, and then the cave takes over — a dark corridor where ankle-deep streams and waist-high pools negotiate every foot of progress. The light from your lamp reveals calcified curtains, shattered pottery, and, farther in, the crystallized outline of what local guides simply call the Crystal Maiden.

Reserve your spot on the A.T.M Cave (Actun Tunichil Muknal) from Hopkins today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Wear sturdy water shoes
Traction matters: expect wet, slippery limestone and ankle-to-waist-deep water crossings—closed-toe water shoes or reef shoes are best.
Protect electronics
Put phones and cameras in a waterproof dry bag; guides restrict flash photography near skeletal remains.
Be honest about health limits
Not recommended for pregnant travelers or anyone with spinal, heart, or serious mobility issues due to uneven terrain and stooping.
Listen to your guide
Guides manage both safety and conservation—follow instructions about where to step and what not to touch.
Closed-toe water shoes
Provide traction on wet limestone and protect toes from rocky riverbeds.
Dry bag (small)
Keeps camera, phone, and spare clothes dry during river crossings.
Quick-dry change of clothes
Swap into dry layers after the cave to stay warm and comfortable for the return trip.
Reusable water bottle
Hydration is included, but carrying your own bottle helps during the hike portions.
