susanktz:I've looked online for ages looking for walking maps, street maps, do it yourself stuff.
Apparently you've never been to Costa Maya.
Costa Maya is a Carnival-built pier some ways south of the Mayan Riviera area with fenced-in shopping, swimming pools, restaurants and bars [one swim-up], and the nearest native population is a teeny tiny rinky dinky fishing village about a mile south called Mahajual.
Mahajual is a collection of ramshackle buildings just beyond the beach which -- on days cruise ships are there -- turn from whatever they are into bars and restaurants and bicycle or kayak rental shops, and the fishermen and the fishwives turn from fishing into beer sales and masseuses.
There are no street maps because there is one street -- if you can call a dirt track alternating between cavernous craters and speed bumps a street -- and there are no walking maps because when you get off the boat you're either going to wander around the enclosed tourist area [or the shopping plaza they were building just outside it when I was there] or you're going to look down the beach to Mahajual and say "Let's walk down there". It's a straight shot.
I'd hesitate to go walking anywhere else because parts of Mexico are notorious for drug gangs and the Mexicans authorities are very keen on keeping same away from places which generate tourist dollars; the Mexican navy is out in force and well-armed.
Costa Maya is a good place to hang loose, grab a bucketful of cheap beers in Mahajual, rent one of those thatched-grass-roof dealies on the beach, maybe get a $20 massage, go wading in the light surf [you're in a lagoon -- the waves break on the reef a quarter mile out], and just chill in the warm shade until it's time to go.
Desperately seeking 10th cruise for the free laundry.
