New River Gorge in the rain

Hello all, my family and I are heading to New River Gorge NP this weekend. I had several hikes planned (2 adults, 6 and 2 yr old). As we have gotten closer, the forecast is showing a good bit of rain. What are your favorite rainy day hikes at New River? As long as it isn't a total downpour, I plan to still get out, just want to plan accordingly.

The hikes I wanted to try and do are: Castle Rock Trail Endless Wall Trail Long Point Sandstone Falls Boardwalk Tunnel Trail Big Buck Trail

If the weather is miserable, we have plans to hit up Fayetteville to check out Beckley Exhibition Coal Mine & Youth Museum, Pin Heads, and we may also venture out to Lost World Caverns.

We aren't made of sugar but with two young kids, don't want to be miserable either. Any suggestions would be helpful!
