Only 1 group can reserve the lake at a time.

How To Reserve Lake/Water Slide »

Safety: For safety, Black Rock provides 2 lifeguards for each activity. You may only swim in the activity where the lifeguards are on duty. When the deep end is open, only 16 people are allowed in the deep end, 8 on the raft and 8 on the manatee. The lifeguards can help monitor equal time and rotations. If you have a larger group it is recommended that you reserve 2 or 3 activities, allowing you to have multiple activities open at one time.

Dress Code: We require that women wear MODEST bathing suits (no bare midriff or bikini) and men wear MODEST swimming trunks (no bikini, Speedo-style). Lifeguards will require women to put on a colored T-shirt if this is not followed.

How To Reserve: Call Guest Services Department at (717) 529-3232 (you can also email us for more information). Advance reservations are required.
