We had a great time camping at Liam's Lair! We loved how selcuded it was. The fire pit and grill really came in handy, and we had the best sleep listening to the creek. We didn't feel the need to leave camp during our stay so we ventured up and down the creek, checked out Hannah's Haven, and cooked some delicious meals. A few things to note, we were given the option of two trails to access our site. The first trail, which I believe is the main Liam's Lair entrance, is a walking path. I'd suggest you only use this path if you are truly backpacking in, all others using carts should be directed to Hannah's Haven entrance along the creek. HH entrance was muddy but considerably better than the goat path mentioned earlier.
Even with the creek as loud as it is, you CAN hear traffic. We did not realize this when booking but throughout the day and night you could hear traffic from surrounding areas.
We stayed at Liam's Lair, but did check out Hannah's Haven as well. These sites are also very nice with creek access, but the sites are very close to each other and no privacy in between. Would definitely be good for a larger group.
Lastly, while we were setting up camp we got word from the host that the prior campers had to ward off a bear that had stolen their trash. It wasn't a deal breaker for us, but could be for some and it would've been nice for Greg to communicate this prior to our arrival.
