This cache is located in Skyline Ridge Open Space Preserve. However, the closest parking is at the Russian Ridge Open Space lot at the corner of Alpine Road and Skyline Blvd. The cache is about a mile from there as the crow flies but since you are not a crow, you will have to put in a lot more effort. As with my other caches, I am not giving any additional information to help you get to the cache. Please do not spoil the challenge by revealing any useful information in your log.
The cache has a log book,a pen and a few British coins. Feel free to take one if you are one of the early ones.
