Online Registration

Summer 2026 Pre-Registration is open now! By pre-registering now, you can lock in 2025 rates and get the opportunity to select your preferred session in December when session dates are confirmed, before registration opens to the general public. As many sessions sold out this year, this is a great opportunity to secure your spot.

To pre-register, complete the registration form online (through UltraCamp). Once the form has been received and reviewed, we will send you a link or information on how to pay the deposit online.

For questions, call 716-664-2802 ext 238 or email the camp office.
