Always clean, good well light parking. Staff is welcoming and helpful. Great bathroom stop if you are traveling through the area. Plenty of grassy area to give your dogs a break.

The Crain Memorial Welcome Center is a very convenient stop along US-301. The place is clean, the restrooms are well-kept, and the staff is friendly. I liked that they offer maps and brochures with plenty of local tourist information, which is really helpful if you’re just passing through. They also have an EV charger, which is a nice bonus for long trips. The only downside is that access and parking for larger vehicles can feel a bit tight.

This is a good place to stop if you are touring Maryland or exploring it's individual counties. They have a vast amount of brochures, magazines and pamphlets for Maryland histories, tourist attractions, etc. If you are driving through and need to stop for food, rest, gas or anything else, STOP BEFORE you come over the bridge or drive 12 Miles on highway 301 to La Plata.
This is not a tradional rest stop with a food court, large restrooms or gas. It is EXTREMELY isolated and not safe to travel by yourself. It's a nice place to walk your dog, but there is Galveston's gas/service station 2 stop lights ahead with bright lights, vending machines, lots of grass and bright lights on the highway and the station. They are not 24 hours, but they accept credit cards in emergency BUT will put a $100 hold on the card if you pay at pump.
Stop in Virginia because you will not have as many food, hotel or shopping options until Waldorf and the Super Walmart is the last one you will see until .... Not sure actually. Just don't panic that you are in a deserted area with nowhere to stop. Do not stop here at night. Drive on through if possible or stop before coming.
Maryland does not welcome you, and I say that as someone who has taken many road trips and lived Newburg, MD for 11 years and moved to St. Marys county from CT when I was 13. If you can stop in VA, do that and if not, drive right on through to La Plata Maryland. Wawa is 24 hours and you will see it after you pass all the other stuff.
If you are into Maryland History and truly want to explore, this place is great. Extremely clean and has an information desk with someone to help answer questions during the day. (Well it did last I was there 2.years ago.) It's hidden on a dark road driving up into a wooded area on the right, but there is a sign. If you have the day to spend in Newburg/Cobb Island, there are some really cool places down here. They may seen few and far between, but they are really amazing. Glory Days Antiques can be a great travel tradition on the way home or to start off the trip. There are great seafood restaurants on both sides of the highway but you have to drive awhile to find them. Maryland is beautiful and there are places and people that welcome you... We just hide off the highway and if you get stuck at this rest stop with no gas, there won't be anyone to help you. The Maryland Transit police do have a tiny station off of the bridge so maybe look that number up before you go. Don't rely on your cell phone service here.
Safe travels, and please take heed.

I have been to this Welcome Center in May and in August. It’s been my go to place in everything you need to know about Maryland’s great history. Kim and Sharon actually remembered me from my previous visit (if you’re 6’ 4” that probably does help)! They were very accommodating to me as well as everyone else that came in. It’s a wonderful and very clean facility, with places to walk your dog or just walk around and look at the Potomac River. My recent visit was to St. Mary’s County. I’d never been and something of interest, since I first read about it. Check out my review regarding St. Mary’s County seat of Leonardtown.

This is a nice rest facility. Lots of good parking close to the building and the facility is well taken care of. There's a very friendly visitor center there also. Rest rooms are very clean.
