Deer & Lang Caves show-cave evening clock.
Plan Deer and Lang Caves as a guided show-cave walk with advance space, wet footing and a conditional evening bat exodus.
Check in at park headquarters early enough to confirm meeting point, guide and current trail conditions.
Briefing, forest approach, two contrasting caves and a patient dusk wait form the chapter.
Stay on the route, avoid flash where restricted and never touch cave formations or wildlife.

Briefing, forest approach, two contrasting caves and a patient dusk wait form the chapter.
