How much would a standard trail ride cost?

$40 for an hour trail ride

are you allowed to gallop with the horses or trot ?

All I have to say is it is totally worth it I even risked my phone to take pictures of the absolutely Serene beautiful scenery along the trails, multiple views of all types of scenery beautiful trails, beautiful as the horses go through water as well and even was able to take pictures with my phone on the horse when going through the water they are that well behaved although there was a rascal horse I believe named trigger who was a hoot who jumped in the party the trail group with us without a rider and he was just joining us to have a good ole merry time :) and the guides were Beyond helpful, patient and amazing! This was a group of about seven of us with a guide in front and in back highly recommend :-)
