I went with a group of seven and we hiked the Collins Rim Trail and the Collin Gulf Trail Loop. We had a blast. The weather wasn’t the best, temps in the mid 30’s and rained the whole first day. The Collins Rim Trail was about 8 miles to our campsite and then 4 miles out on the Loop Trail. You do have to reserve a campsite, even though someone else took ours, there were plenty of campsites available due to the weather. Parts of the trail were moderately difficult due to the geography and other parts were made more difficult from the rain. Overall this is an amazing place to day hike or even camp like we did. The views were amazing and the waterfalls, lots of water falls! We will definitely be back!
