I was thinking of another one today. Going up to Las Cañadas caldera after sunset to see the stars is absolutely amazing. You can see millions of stars. At that altitude there is no moisture ,so no haze,the air is a bit thinner and there is no light pollution. You can see all the stars in Orion very clearly,instead of the few you can see near the beach.The orion nebula is much clearer.The milky way looks fantastic.Just like the photos you see.A big band across the night sky.There is also millions of stars you would never see normaly in the night sky.

If you go up during a metor shower,the metors are much clearer.I saw a few with firey tails.Well worth a visit. Wrap up this time of the year.
