Reserve your spot on the Sky Explorer Schooner and Sentry Hill Line Tour St Maartin today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Hydrate Before You Climb
Bring water and hydrate in advance—operators have limited time on the summit and little shade between platforms.
Wear Secure, Closed-Toe Shoes
Sturdy sneakers or trail shoes keep feet secure for boarding, harnessing and the tubular slide exit.
Sun Protection & Wind Layer
Sunscreen and a light windbreaker matter—sun is strong at elevation and trade winds can cool you rapidly.
Know the Height/Weight Limits
Check limits ahead (zipline min 52 in/80 lb; max 275 lb) to avoid surprises at check-in.
Closed-toe shoes
Secure footing for boarding gondolas, zip-line platforms and the schooner slide exit.
Sunscreen & sunglasses
Strong sun and reflection off water increase UV exposure at altitude.
summer
Light windbreaker
Trade winds and higher elevation can cool temperatures quickly during morning or late afternoon.
spring
Small daypack or secure pocket
Carry water, ID, and phone; operators may require phones be stowed during zips.
