Just a quick note to acompany my photos of Media Luna.
I was invited to go to this pine forest/lake by one of my students and his friends. We just went for the day as it's only about 1 1/2 - 2 hours from San Luis Potosi - in fact it's still in SLP state and on the edge of the green, pretty area of mexico called La Huasteca, which is somewhere i definitely want to explore a bit more when i have the chance.
Media Luna is a little bit done up for tourists (but not too much) and a really popular place for mexican families at the weekends as you can swim in the lake (which was surprisingly warm - it was a hot day but still the water was so nice especially for such a deep lake!) and the rivers and have picnics or barbeques in the pine forest next to the lake. You can even camp there in the forest.
Despite having a bit of food poisoning from my dinner the night before, I enjoyed the day and it was really nice to get out of the city and be somewhere relaxing for a change! It certainly made me keen to see more of this area of Mexico and not just the cities as Id been planning so far.
