I was at ISP last month and found the same as reported above. The green one transports between the two docking areas and the the red one ($49 plus tax) goes to the top for the great views, access to the zip Line and a short walk to a small lake (pond) area. It appears there is a plan for a tram to move some around on top but I didn’t see one while there. The walk to the lake is short and more or less flat. The walk to the zip line area has a pretty steep downhill and unless you have prepaid for the zip line I wouldn’t recommend walking down this road for most people because the return trip will be challenging for many folks. If you want to get your heart really pumping on a short walk go for it but you been warned.
I waited to purchase the Red ticket until I was at ISP to make sure the mountain top was clear before buying. The price of $49 seems a little but high but the views were awesome and best enjoyed right a the bottom of the unloading are a few hundred yards from the top.
