They do offer WiFi, I can’t attest to the strength of it though. It wasn’t very strong at our particular site. There are several great bike paths all around the park. You can do a lot of exploring on bike. They are mostly paved and some are gravel.
I believe they offer wifi but I do not recall the strength of signal...there are multiple bike paths within the campground and park. The park website should display the bike paths. There are some good YouTube videos/reviews also.
Hi, we stayed there in 2017. The trail/boardwalk system and paved bike paths were awesome. You can access the Hugh S. Branyon Backcountry Trail System from the park. We biked over 25 miles and still didn’t do all the trails. The park had wifi, but it didn't work in our site. No idea if it's been upgraded since then. Enjoy!
