National park is vast.....i found camping without obtaining forest pass,and enjoyed my weekend. It's alwYs smart to get adventure pass,but is possible to still find the untouched spots. .....no I do on the crystal caves sorry.
Crystal cave has to have tickets that you obtain at the Lodge Pole visitor's center. Yiu have to pay for those. Morro Rock is fine. All the trails in the general area are free but yiu have to obtain a wilderness permit fir the back countey trails. If you have any questions, ask the rangers. They're awesome.
Crystal cave needs reservations. Mottow rock is fine. Back packing needs permits
