This is a great hike for the advance hiker. I began at Jones Gap State Park and hiked to Caesar Head Ranger Station. The trail begins easy, but once you pass the second spur "Pink" trail about 2 miles in, it begins to get hard. It is more of an obstacle course than a hike, over, under, around, even through "fat man squeeze" rocks and drop offs. While constantly looking over the edge of cliffs, down into Jones Gap. The views would be better in Autumn or early winter. However, you cross a lot of small mountain streams that would make it very slippery or icy in winter and believe me you do not want to start sliding, the trail's name is exactly what it means, "Rim of the Gap". It is a challenge and breath taking and exciting all the way through. There are several different distances posted for this trail but I think the total distance from Jones Gap to Caesar Head is about 5.2 miles including the Elliot "Purple" trail that ends at the Caesar Head Ranger Station. The yellow markers on the trail are easy to follow, there has been a lot of maintenance recently done on the trail, and no problems following the trail. I would be careful on a few of the ladders you have to climb up or down, they do need to be replaced and there are two steep rock drop off you have to be careful on. But hey, if you want an easy trail hike the Swamp Rabbit. It took my friend and I 5.5 hours to complete this hike. You can't go fast while on the Rim, one wrong step or a tumble and you're over the side. If you want a challenge, that will test your hiking skills, hike "The Rim of the Gap". You will love it. Also, I get tired of hearing people say "This trail isn't for old people". I'm 60, and did the trail, just make sure you're in good shape before attempting this trail, it's not a trail to hold hands on and skip along counting butter flies and picking flowers.
