From the GG did you continue south to check out the tunnels leading to Route 1 -- under the Presidio -- toward 19th Ave. and I-280 which goes down the Peninsula to San Jose? [the reverse of the route suggested a few days ago] Or did you head toward downtown SF (east) after you crossed the bridge?

It would be helpful for everyone to know if the southbound tunnels under the Presidio are new, and if they are open to RV and trailer traffic, as this would be a far simpler path to go back south IMO, given that you are just a little north of the Golden Gate Bridge. Returning via the East Bay and I-680 or another route seems like "The Long Way Back to Pasa Robles." [sounds like the beginning of a new screenplay!]

Or maybe you are continuing north to Washington and home?

Thanks for the update and Happy Trails!

Thanks SiennaGuy for the answer about the MacArthur Tunnel. With it being OK for RV's it seems like the easiest southbound route from Larkspur RV park to Pasa Robles would have been via the GGB and this tunnel to I-280 to San Jose, then south on 101 IMO.

Here's an expanded message. I deleted the one the Otra15 replied to include more info.

There are several tunnels under the Presidio. One set of them connects the Golden Gate Bridge to Richardson Ave. and then to Lombard St. (Highway 101). There are northbound tunnels and seperate southbound tunnels. These are known as the the Doyle Drive (or "Presidio Parkway") tunnels and they recently opened. An RV shouldn't be a problem. Here's the photo that I posted earlier.

Notes: This part of Lombard St. is a regular, heavily trafficked city street. This is NOT the part of Lombard St. that's known as the Crookedest Street in the World (There's no way to drive an RV down that crooked part of the street). Also, if you're headed north on this route, one of the last buildings that you see before you get on the bridge approach is the Palace of Fine Arts. It's on your right. It was originally constructed for the 1915 Panama-Pacific Exposition. It's brown and has several columns and a dome that you can see from your vehicle. If you're headed south, it's one of the first buildings you see as you enter San Francisco, and it's on the left.

There's also a tunnel that connects the Golden Gate Bridge to Park Presidio and then to 19th Ave. (Highway 1). This is the General MacArthur Tunnel. One tunnel serves both northbound and southbound traffic. There's a concrete barrier between the northbound and southbound traffic. It's not new, but you shouldn't have any problems with your RV. I frequently see big RVs going through this tunnel.

If you decide to go down the coast on Highway 1, there are another pair of tunnels in Pacifica, which is about 30 miles south of San Francisco. These are known as the Tom Lantos Tunnels (or the Devil's Slide Tunnels). These are new and like the others, you should have no problem with an RV. These tunnels replaced the old Devil's Slide road. It was called Devil's Slide because parts of that old road would fall off the cliffs during landslides. Chunks of roadway would end up in the ocean almost every rainy season. The new tunnels avoid that old route entirely.

More on tunnels in the San Francisco area:

The San Francisco-Oakland Bay Bridge is made up of two sections. One section goes from San Francisco to Yerba Buena Island. The other section, the eastern section, goes from that small island to Oakland. The two sections are connected by a tunnel that goes through the island. While it's high enough to handle RVs and big trucks, there have recently been problems with chunks of concrete falling from the inside of it. You may not run into problems but expect there to be construction delays until they fix it.
http://www.sfgate.com/bayarea/articl...nk-6812704.php

By the way, the eastern section of the bridge is new. It's really beautiful any time but at night, it's spectacular. During the day, you'll see the old bridge being torn down, which is fun to watch.

Highway 24, east of San Francisco, has yet another tunnel. This is known as the Caldecott Tunnel.
https://en.wikipedia.org/wiki/Caldecott_Tunnel

There are several bores through the hillside, each handling a lane or two of traffic. Big trucks go through it, so RV heights should pose no worries. I couldn't find any propane restrictions, either, HOWEVER, the Caldecott Tunnel was the scene of a horrible fire in 1982. A gasoline tanker truck exploded in the middle of the tunnel, killing 7 people. The tunnel acted as a chimney for the smoke and flames. These kinds of tankers are no longer allowed there unless it's in the middle of the night when there's no traffic. Still, I'd make sure that your propane is OFF before you enter this tunnel.

Here's some info about the Palace of Fine Arts that's near the approach to the Golden Gate Bridge:

Even more on tunnels in the San Francisco area:

There are two small tunnels that connect Alameda (an island in the bay) to Oakland (a city in the east bay). They're known as the Posey Street Tube and the Webster Street Tube. They both go underwater under the bay. These are old tunnels--according to Wikipedia, the Posey Street Tube opened in 1928 and the very similar Webster Street Tube opened in 1963. They both have height restrictions. The maximum height for both is a bit over 14 feet. I wouldn't go through them with an RV.
Here's a map:

Here's info about these tubes:
https://en.wikipedia.org/wiki/Posey_...r_Street_tubes

As alternatives, there are bridges that connect Alameda to Oakland, the closest one to the tubes being the Park Street Bridge.
https://en.wikipedia.org/wiki/Park_Street_Bridge

Here's a map of the Park Street Bridge:
https://www.google.com/maps/place/Al...ff99cf60016f14

A bit of trivia: The Pan Am China Clipper sea planes once used Alameda as their airport. They also used Treasure Island, also in the San Francisco Bay. Treasure Island is an artificial island that was built off of Yerba Buena Island for the 1939 Golden Gate International Exposition. As I mentioned earlier, the San Francisco Bay Bridge has a tunnel that goes through Yerba Buena Island.
