You'll be hiking at 10,000 feet altitude and the walk around the lake has ups and downs. Around the whole lake would take many hours. I am no expert on pregnancy, but I imagine if you are accustomed to the altitude by then you can manage a short walk and head back before you get tired. I don't know your situation, but I don't recall that there was parking there. I hope this helps.

En el Lago no hay espacios oficiales establecidos para acampar, se podrìa acampar en otros lugares. Sin ninguna seguridad. podriamos ofrecer otras posibilidades para acampar

Si puedes llevar mascotas al lugar, en el bote que te hace la vuelta en la laguna es donde no se puede trepar

Si lo puedes dejar, hay un guardia que está todo el tiempo. La entrada al parque no tiene costo, pero es posible que el cuidado del carro si.

Hi! I remember there isn't taxis in the place. It's better to speak to the driver to wait you or return to pickup. Cuicocha isn't too far from Cotacachi.

I have seen egrets over there

Sólo quiero agregar algo a lo importante de los comentarios anteriores. Otavalo es un lugar digno de visitar y pasar un par de noches. La feria artesanal, la gente, los mercados y a eso agregarle la laguna y el "pueblo de los cueros". También hay excursiones más largas a alguno de los otros volcanes.

I'm not sure the best way to hike it since I took the boat, but you are hiking around the crater rim and arrive at the same spot so you would have similar elevation differences either way. As far as getting there I'm assuming you are going from Otovala. You would take a bus to one of two towns nearby and from there a taxi is $5 to the crater. You can have him pick you up at a certain time comin back or just snag a taxi dropping someone else off. You could also hitchhike back into town fairly easily if you are comfortable with that.

La vía esta en buen estado, no tendra problemas con su vehiculo..... Saludos

i´ve done it with either running shoes or hiking shoes. Not an issue
