The Hike: The 400 acre Big Island has no trails, and is
a cross country hike. The Island has three knolls, blue oak woodland,
grassland, and some shrubs. I usually traverse the entire island
for a hike, starting at the grassland on the southwestern edge of the island,
hiking to the northern knoll, then backtracking to the southern knoll.
The views of the lake, Blue Ridge, Rocky Ridge, Berryessa Peak, Cedar Roughs,
and the rest of the shoreline, are spectacular. The grasses are short
bunch grasses on the majority of the island, but the southernmost tip of
the island has some star thistle. Avoid that area.
One nice thing about the island is that very few people hike on it.
Most of the lake's users are boating or water skiing, so there have been
days when the lake was packed but I was the only one on the island.
On the island, you will see foothill pine, blue oak, buckeye, and manzanita.
In the spring, the fields of Lupine are outstanding.
