    A very small, but fun state park. You really have to get out among the woods for this park to be at it's best. Incredibly good for hiking. Lots of trail loops you can make within the park, or use the adjacent Tuscarora forest for some nice backwoods options. My friends and I camped for the night and did a 6 mile hike around Tuscarora forest on the first afternoon. Then the next day hiked Flat Rock. My one big gripe is there was some deforestation/logging action going on on Cider Path Trail. It was a very disheartening, something I'm not used to seeing firsthand. Makes me realize there are so many reasons to keep these places sacred and worthy of visiting.

    One of my favorite parts about hiking is talking to other hikers! A few weeks ago, while wrapping…read moreup a different trail, another hiker asked where else I liked to hike. When I admitted I'd never been to Opossum Lake, she looked at me like I was missing out and told me I needed to check it out. Well...challenge accepted! When I got home, I looked it up and discovered it was only about 25 minutes from my house. Somehow, yet again, I had managed to overlook another great outdoor spot practically in my own backyard. A beautiful four-mile trail around a lake? Count me in! I headed out early on a mid-July Sunday morning, hoping to beat both the heat and the crowds. GPS brought me right to the parking area without any trouble, and even though there were already quite a few people there fishing, I had no problem finding a parking spot. The trail itself was fantastic! One of the things I appreciated most was how much the terrain changed throughout the loop. Parts of the trail were covered with crushed stone, others with pine needles, tanbark or natural dirt. It kept the hike interesting without ever becoming difficult. The entire four-mile loop is well-marked, easy to follow and beautifully shaded, making it an excellent summer hike even when temperatures start creeping up. The recent rain left a few muddy spots along the trail, but nothing that slowed me down. PRO TIP: If you're hiking after a rainstorm, use a little extra caution on the wooden footbridges. They can get a bit slick. The trail offered plenty to see along the way. I spotted birds, turtles and beautiful views across the lake and I found myself stopping more than once simply to enjoy the peaceful scenery. One unexpected highlight came when I crossed the spillway bridge. The interpretive signs explaining the history of the dam, the high-water markers and why the bridge was built so high above the creek added a neat educational element to the hike that I wasn't expecting. I always appreciate when a place teaches me something while I'm out exploring. Beyond hiking, it's easy to see why Opossum Lake has become such a popular recreation area. Throughout my visit I saw anglers casting from the shoreline, boats out enjoying the water and families making use of the many picnic areas scattered around the lake. Whether you're looking to hike, fish, paddle or simply enjoy a peaceful picnic, there's plenty of room to spread out and enjoy the scenery. I can already tell Opossum Lake is going to earn a permanent spot on my short list of local hikes. It's close to home. It's easy enough to enjoy without needing to mentally prepare for a mountain expedition. And it's beautiful enough that it never feels like "just another walk." Sometimes you want a huge adventure. Sometimes you just want to lace up your hiking boots, get a few peaceful miles under your belt and spend some time outside. Opossum Lake is absolutely perfect for those days!

The distance around the lake is, I think, about 3 or 3 1/2 miles and there are some small hills, steps, and mostly dirt or pine-needle-covered terrain. In terms of kayaking, I can paddle around all areas in about an hour. It's a convenient, easy-to-get-to location and it's open until 10pm.

I stopped by on a warm, sunny October Sunday morning while in the area for the National Apple Harvest Festival (about 30 minutes away), and somehow had the whole place to myself. It was so peaceful--just the sound of leaves rustling in the breeze and the occasional thud of acorns falling from the trees. The walk in is short and easy--basically a flat stroll past a couple of informational signs to reach the boulder outcropping. From there, the fun begins! Hammonds Rocks is about 400 feet long, with massive stone formations to climb, wander, and explore. I spent about 45 minutes hopping from stone to stone, taking photos, and checking out different angles of the formations. Even without climbing, there are plenty of spots to enjoy the view, though the tall trees do block some of it. Still, with the leaves just starting to turn to their fall colors, it was absolutely beautiful. The info signs are worth a pause, too--they really put things into perspective. One noted that when the sediments making up these rocks were deposited, the spot where I was standing was on the shore of a great ocean...530-600 MILLION years ago. Wild. Absolutely mind blowing! As for access: don't panic when Google Maps tells you the next few miles are unpaved. The gravel road is manageable if you take it slow and keep an eye out for some monster ruts. (Speaking from experience: this 40-something woman in her beloved Alfa Romeo made it just fine.) Just don't attempt in winter without knowing what you're getting into--the roads aren't maintained in snow or ice. Overall, Hammonds Rocks is an easy, low-effort, high-reward stop. Whether you're climbing, photographing, or just taking in the history and scenery, it's a great way to spend part of your day in Michaux.

There are 18 rustic campsites, with water fountains/spigots, non-flush toilets, picnic tables, and grills available for campers and day use visitors. There are garbage cans available, but it is advised that you pack out your trash if possible. The roads leading into and out of the park are unpaved and are not plowed in the winter. Four wheel drive is not necessary to get there, but if you drive a car that is low to the ground be aware that the trip up will not be the smoothest. We spent a long weekend here in mid October, and while there were a few other couples and families camping on Fri/Sat night, on Sunday we were completely alone. It was isolated and a little creepy, but ultimately it was really nice to be away from civilization! Rangers drive through a couple times of day. There are some nice trails, lots of wildlife (keep your food in your car, if you don't want to be visited by foxes and coyotes in the middle of the night) streams, and a pond that is stocked for fishing. It is a nice, quiet place to kick back & enjoy the outdoors. I am really looking forward to visiting again!

    I recently discovered LeTort Spring Run and Nature Trail, and honestly, I'm still annoyed with…read moremyself for not knowing it existed sooner. I've lived in Central PA nearly my entire life--and even in Carlisle--and somehow this peaceful little gem flew completely under my radar until it popped up on social media a few weeks ago. Once I realized it was only about a 20-minute drive from my house, it immediately earned a spot on my must-visit list. Naturally, I wasted no time--early the very next Sunday morning, LeTort was my destination. According to LeTort's website (and because I love a little history with my walks): the trail is named after James LeTort, a French-Swiss trader who settled near the stream in the early 1700s. The area once hosted mills and tanneries and later became internationally known for cold-water fly fishing. Today, LeTort is famous for its limestone trout stream, bird watching, and a 2.5-mile out-and-back trail that's wide, flat, and easy to navigate. There are multiple access points, ADA-accessible fishing platforms, interpretive signage, and plenty of opportunities to feel outdoorsy without having to scale a boulder or question your life choices. I parked in the newly developed lot on South Spring Garden Street and was thrilled to find...absolutely no one else there! Sunday morning hikes are sacred to me--they're about quiet, reflection, and resetting my brain for the week ahead--so having the entire place to myself felt like winning the nature lottery. The sun was just coming up, casting that soft, golden morning light that makes everything feel calm and slightly magical. I specifically chose LeTort because it promised well-maintained, ADA-accessible paths, as opposed to my usual "billy-goating through the woods" adventures involving rocks, roots, and questionable footing. This particular Sunday, my brain was heavy and my soul needed something gentle. LeTort absolutely delivered. I didn't pass another human the entire time I was there (10/10 experience for me), but it's clear this trail would be perfect for folks with strollers, dogs, or mobility aids. The paths are wide, flat, and beautifully maintained, with lovely views along the stream. Wildlife was very much awake and active--squirrels were busy being chaotic, birds were everywhere, and a few mallard ducks were enjoying their best peaceful-morning lives. My two favorite moments from this visit really stood out. First was the view from a bridge near Bonny Brook Road, where I stopped to watch ducks gliding through the creek while squirrels chased each other across fallen trees spanning the water. It was serene, peaceful, and exactly the kind of quiet beauty I needed. The second moment surprised me: a Sharpie-marked message on a wooden signpost that read, "ALWAYS HAVE HOPE." I'm not usually a fan of graffiti, but that message hit me square in the feelings that morning and felt oddly meant just for me. Sometimes the universe shows up in weird ways--even via Sharpie. LeTort Spring Run is a solid choice for a low-impact, easy walk when you want fresh air without breaking a sweat or navigating rugged terrain. There's plenty of parking, plenty of space to move comfortably, and plenty of beauty if you're paying attention. It may not land on my frequent-visit list, but I'll absolutely keep it in mind as a future picnic spot once spring and summer roll around. Sometimes the best adventures are the quiet ones--and LeTort is a really lovely place to slow down, breathe, and just be.

    This is a rather easy and underwhelming bike trail, but an OK one for walking/jogging. The reason…read moreis it's only 1.7 miles long. The trail is narrower than a typical rail trail and is paved with crushed stones. Best parking for the trailhead is at the Lamberton Middle School. In the visitor parking just head toward the building and veer to the left and you will see the trailhead. At the end of the trail at S Spring Garden St, there's a posted sign announcing the extension of the trail all the way to Heisters Lane and is expected to be completed in July of 2021. That would add at least .9 miles to the trail, making it more presentable and worth while to visit. Officially the trail starts from LeTort Park which adds .3 mile to the length, but that would include 3 blocks of street biking interconnecting the 2 segments. By the way, LeTort Park has a nice setting for duck and goose watching if you're into that sort of thing.
