High Falls Gorge has beautiful waterfalls! The gift shop has very good food. Overall it is a little bit pricey but well maintained. I believe it is handicapped accessible. Total time here..30 minutes.
If visiting in the winter, they'll build a fire for you to roast marshmallows after viewing the frozen falls. You also get a free hot beverage in the charming lounge area. There's even free wifi!
They have nice walkways built all along the river and waterfalls so you can walk along and get great views. Cafe is small and the drinks weren't very impressive, but the food was great!
Good hike. Bring sneakers if you plan on taking the nature or "hard" path. There is some handicap accessibility areas and trails, and the mining for kids is a good deal.
