First of all, the Niagara Glen Trail is magical. What an amazing trail this is. The lookouts over the Niagara River are second to none. The whooshing of the water as it rushes past you is soothing and exciting at the same time.
The Park consists of rock carvings (Petroglyphs) and a meromictic (layers of water that don’t intermix) lake called McGinnis Lake. It’s worth checking out.
