For starters I have only walked the Lake Loop and around the main water area, but I had a fantastic time. The trails are well kept and wide with easily seen trail blazes throughout the entire path. The Lake Loop in particular is a wonderful short trail (about 3 miles) that traverses around a couple of different lakes with some spots to let the doggos dip their feet in order to cool off. This loop is relatively flat and would be a great beginner trail running route or mountain biking trail. The trail head is located at the south-east end of their ginormous parking lot.
No trail maps are in the parking lot, so I would recommend having one on your phone or taking a good peak at one before arriving so you have an accurate idea of your surroundings.
I will definitely be back to try all their other activities! I took a little gaunt around the main water area with my doggies and had a wonderful view of people practicing water rescue, whitewater rafting, kayaking, and zip lining. Bonus points... this place has a lovely biergarten!
