What is the cost per person for trial rides? Do you need to make advanced reservations?

I did make reservations when I went. As far as the cost they have various prices for length of rides and special sunset rides or ice cream rides which are all very affordable. I believe 30 minute to possibly an hour trail ride is 65 per person, 120 for a couple, and 220 for a group of 4

I would reserve in advance cost us 65 per person for an hours walk
