The Great Outdoors

Union City lies on the edge of the Eden Landing Ecological Reserve, a wetland of salt ponds and marshland along the eastern shores of San Francisco Bay. It supports a diverse number of both resident and migratory waterbirds, such as ruddy ducks, Canadian geese, and Northern shovelers, as well as acting as a nursery for salmon and rainbow trout. Follow one of the hiking trails that lead through its exposed mud flats and tidal marsh habitat or explore from the water while kayaking. You can also visit the Hayward Shoreline Interpretive Center on the northern edge of the reserve that explores the natural history and aquatic life of San Francisco Bay’s wetland and shoreline ecosystems.

My wife and I had an amazing time on our trip with Sid's van. The van was clean and very thoughtfully designed. It was easy to drive and had everything we needed to make our trip enjoyable. Sid was very communicative and professional. We would highly recommend renting this van and are looking forward to doing so again in the future.

As first-time RV renters and Outdoorsy users, we weren't sure what to expect — but this experience completely won us over. We took the Mercedes Entegra Qwest 24R down to KOA Santa Cruz for a weekend trip with our family. It was everything we hoped for and more!

We booked the Flynn Rider to travel to Northern Arizona, southern Nevada as well as up through California. The van had everything we needed. It is equipped with pans for cooking, dinnerware, utensils etc. We were able to successfully dry camp off the grid and never had any issue with losing battery power. We stayed in warm climates and were able to keep the generator on which powered the AC which was really nice. The van is also equipped with a microwave which was convenient as well. It has a lot of digital additions such as wireless chargers, a nice navigation screen up front and you can plug in your phone for CarPlay. We upgraded to have the Starlink which was huge in staying connected in places where there is no cell service. There is a hose for the outdoor shower as well as an indoor shower. The bed was also very comfortable. Bon was a super responsive host - any questions we had, he responded immediately and was very helpful, and we appreciated that as we were first time camper van utilizers. I also appreciate the flexibility in pick up and return times which one may not get with going through commercial camper van rentals. We were also able to leave our cars in Bon's neighborhood which was a safe option. We thank Bon for a great experience and hope to rent again in the future!
