BE AWARE: Massive mosquito Infestation at Sea Rim SP as of 12/2023 - and is an ongoing problem. Full details 👇🏼 Giving 4 stars because the park itself is clean and well maintained. The staff/rangers are friendly and helpful. We saw the rangers out every day checking on things and maintaining the property - which was excellent. They all deserve 5 stars! But dropped a star because potential guests NEED to know about the mosquito situation and the state website should add it as a warning for this campground (like states do with wildfires/burn restrictions and other important things). Upon arrival, just rolling our window down at the check in, we were swarmed by mosquitoes rushing in to our B van. You can literally not be outside without DEET and even then, we recommend long sleeves, pants, socks and a netted hat would be ideal. Make sure you cover as many of your outside vents on your rig as possible - the mosquitos will come in through your furnace/fan vents and any other tiny fissure they can find. Yes - covering those vents will also make your rid muggy and humid inside. 🤷🏼‍♀️ The mosquitoes are worse. We booked and stayed 4 nights. As full-time RVers for 2+ years, we have stayed in all kinds of places, climates and circumstances. I've never had an issue with this many mosquitos - anywhere. We literally couldn't leave our rig, absolutely couldn't cook outside (we did the first night, but plan to be cooking and eating inside for your sanity and health), and we definitely couldn't build a fire. Carrying trash to the bins makes you a target and you'll literally be covered in mosquitoes, like they are glitter someone through on you (but if glitter sucked your blood 😱). We saw multiple rigs arrive and leave before their first night started (it's that intense). Every night before bed, we'd kill as many mosquitos as we could find in the rig (make it a game so it is less creepy to think about). But by our fourth night we clearly had hundreds of mosquitoes hiding out in our 21 foot van. Turned our AC on every night to keep the rig cold enough to, hopefully, make them less active while we slept. The beach itself is beautiful and the coastal winds keep the mosquitoes at bay there, but that's the only reprieve. There is a boardwalk over inland water that was also enjoyable and fairly mosquito free. Those were the only times we got to experience "the outside". Our site had partial hook ups, no issue there. The dump station is actually a little less than a mile from the campground (not on site) and as expected, it is a mosquito nightmare to use. There is virtually no cell service and the Wi-Fi is too slow to be useable. Which is crazy bc you can't be outside and then there is nothing to do inside.
