I have visited Carlsbad Caverns, Mammoth Cave and Kartchner Caverns but never have I felt a awed as I did at Timpanogos Caves. But you really have to work for it. The trail to the entrance is only 1.5 miles but the vertical climb is about one thousand feet (starting at over 6000 feet). They allow you an hour and a half to get up there and we needed every minute of it. The path inside the cave is not strenuous but there are some narrow places and several low places to duck under. That said, however, I recommend anyone who can visit this natural wonder.
This is a great place - once you get there!!The hike up to the entrance would be challenging for people unused to a steep hike and I wouldn't recommend you try to take younger children. That said, if you can take the hike up then the experience in the caves is well worth it :)
The hike to the cave is quite long and steep, however, there are benches along the way if you want to stop for a break. As others have mentioned, it is best to go in the morning before it gets too hot. It is cold in the cave so you may want to take a light jacket. Take water and snacks with you as well as a camera for the beautiful views you will see along the way. The cave is very interesting and fun to go through. It is well worth the long hike. Going down is not difficult but you need to watch children as it is very steep and once they getting running they may not be able to stop and go right off the edge.
Tinpanogos is actually three interconnected caves discovered at different times. The temperature is always hovering around 45-50 in the cave so dress accordingly. You should schedule in advance a tour time; then it is recommended you leave the visitor center where you pick up your reserved tickets 90 minutes before your cave tour actually starts; this gives you plenty of time to walk up hill to the cave on your own. The guides meet you at the cave and they conduct a great tour of the unique set of caves.
The guided tour through the system of caves it easy and absolutely beautiful. The rangers are able to explain all the amazing sites and allow ample time for all the photographs you want to take.The tough part is getting to the caves. I suggest you make the trek up to the caves early or late in the day to avoid the heat. It is a 1 1/2 mile strenuous hike up to the caves. You need to be in fairly good health. A local group of seniors makes a timed walk up to the caves several times a week just for the exercise. They kind of humbled me as the passed by as I panted and sweated my way up the hill!
