Please note that Viator( whos reps have never done this activity) wrote the OVERVIEW description that calls this both a tour and scavenger hunt and says i'll be explaining the ecosystem on the river. Unfortunately these inaccuracies are not easy for a suppiler to change. This is a great activity for the right people and I dont wish to mislead anyone. I host and interact with my guests on Whats App. Its not a guided hiking tour. I am a scavenger hunt host and have hunts in both Taos and Santa Fe. This isnt really a scavenger hunt. Its much slower paced, creative and is more about connecting with the land. There are creative exercises. I do give you interesting background on the area but i am not a biologist who is qualified to explain the eco system of the river. if you play this solo, I am happy to host you but know that i cannot provide you with a group to play with. id say a degree of being comfortable alone on hiking trails is essential if you book solo.
