So far this year, we've visited Calaveras Big Trees SP six times. The first time was the day after the last snow, and the most recent was yesterday (July 23).
For literally decades, I took this park for granted. In elementary school, we took field trips to this park, so as I got older, it didn't seem very special. Sort of like, "Hey, look, there's a big tree. There's another one. And another one. There's a lot of big trees here. Big trees? Big whoop." It wasn't until one time we visited and met a couple vacationing from Boston, and they were marveling at how big the trees are, and the forest in general. Seeing the park through their eyes made me realize once again how special Big Trees SP is, and what a wonderful resource, too. Fresh air, a burbling river and creeks, and mostly peace and quiet. And less than a 2 hour drive from home, too.
We have hiked most of the trails in the park (not counting the fire roads), and they all have something different to offer. The Lava Bluffs trail comes alive with wildflowers in the spring, but you have to hit it at the right time of season, and if you're going in late spring or any time during the summer (the wildflowers will be gone by then), take a LOT of water, because the trail gets a lot of sun and you can dehydrate quite easily. Trails in the South Grove area are less crowded because they require a longer drive from the Visitor's Center, but they're well worth the effort.
I've fished in both the Stanislaus river and Beaver Creek in the park but have never caught anything. I know there's fish, because I can see them. I'm just a lousy fisherman. I wouldn't say that I didn't have any luck, though, because I consider myself lucky to be able to spend some time by a beautiful stream with a line in the water no matter what happens. Anyway, that's why it's called 'fishing' and not 'catching'.
We have also taken our bikes (regular bikes, not e-bikes) to ride at CBTSP. Let me tell you, the ride down to the river was fun, fun, fun! OTOH, the ride back up was very much less fun. Got a great feeling of accomplishment from riding back up that long, steep grade, but not something we're planning to do very soon!
This is not unique to CBTSP, but the rangers and docents put on a lot of programs during peak times. You can take a birding walk, see wildflowers, or explore the night sky (I think that's actually the program for tonight, July 24 - I wish we were there!), or a ton of other fun and interesting things. Also, as others have mentioned, many local libraries have State Parks Passes to check out and use for free. Our local library lends the passes for three weeks.
