Geocache Description:

Public parks are one of the treasures of the Bay Area, and not just for geocaching. This challenge is to get you out and enjoying the parks of the East Bay.

There are more than 60 parks in the East Bay Regional Park District (see link above), plus more than 20 regional trails. More are being opened all the time, and new ones will have caches within a day or two of the opening, if current practices continue. Not all of the parks and trails have geocaches and some are not open to the public except by escorted tour, but I’ve counted over seventy parks and trails that are open and have at least one cache. That is your challenge:

Find fifty caches in fifty parks or regional trails administered by the East Bay Regional Park District.

All cache types or events may be counted in your list; puzzles, multicaches, and letterboxes may be included if the posted coordinates are in the park or on the trail. Only finds logged on on or after May 1, 2010, may be counted for this challenge. Any caches found past or present may be included.

The cache is a small pill bottle and is next to an unmapped path, with no bushwacking required. A little poison oak is present but easily avoided. The path is somewhat steep and, depending on eucalyptus litter, may sometimes be a bit slippery in places. Difficulty and training ratings listed are for this cache; the other fifty caches have their own ratings.

You may post a note that you have visited the cache (and sign the paper log) before completing the challenge, but you cannot claim FTF or otherwise log it online as found until you have completed the challenge by providing a list of the fifty caches with the park or trail where you found them and when. Your list can be included in your log or as a bookmark list.

Some parks seem to be conjoined and/or jointly administered (e.g., Roberts and Redwood, Garin and Dry Creek/Pioneer). You may count finds in each park according to how they are listed on the EBPRD web site. Thus, Wildcat Canyon and Tilden are separate parks, but the Tilden Nature Area is part of Tilden and Crab Cove is part of Crown Beach.

Some regional trails pass through some parks. You may count a cache found on a trail in a park for either the park or the trail, but you may not count it for both.

Park maps may be downloaded from the web site above. Trail maps, where available, and trail descriptions, where maps are not available, can be found at

Happy Caching!
