You can walk up to the entrance of el Morro but they close at 6:00 pm. The view is magnificent. Do not go down to the cemetery in the early evening and stick to the streets that have a lot of pedestrians.

Buenas noches Al Católico San Cristobal pagas la entrada lo vez y disfrutas y si ese día no puedes ir no pasa nada porque en los dos sitio se hace un pago por separado que solo es válido por ese día sí vaz otro día tienes que pagar

Taxis are sooo easy to find there. All the white cars are taxis and they have a flat rate based on distance so every taxi will charge the same. Our hotel had some sitting out front all the time just waiting for people

I would recommend the stroll, as others have, if you depart from the San Juan Bay dock. Nevertheless, take a Uber when in heavy rain or extreme heat.

I'm sorry, I am not currently in Puerto Rico at the moment. I know power has returned to a few places within Old San Juan - so that's a start. Sorry I couldn't be more help. I'm not sure when the National Parks will open. If you are going and want to walk boardwalk next to the walls of the fort, you may be able to go to San Juan gate over by Del Morro (the other fort in Old San Juan) and follow the path there. If you are looking for some visual representations, you can always check my YouTube page at Josh the Travel Guy. I have a host of videos on Old San Juan and beyond. These were all pre-Maria though.

De 9 de la mañana a 4 de la tarde y si llegas temprano la taquilla de San Cristóbal la misma puedes usar para El morro

This is a US National Park so their rules apply. Here's the link to that site: .nps.gov/aboutus/news/commercial-film-and-photo-permits.htm. Based on my reading of this, you'll be fine.

I beleive it's about a mile

Sorry can't answer this one. Was only there to visit the Fort and not for a wedding

The forts are not far from the Cruise ship area...easy taxi drive. There are signs and the taxi can drop you off at the entrance. Remember, there are actually two forts, about a kilometer apart...Castillo San Felipe del Morro and Castillo San Cristobal. The cost of entry is $5.00 and it is good for both forts...just keep your receipt. Morro is the larger of the forts and is right next to the cemetery. Critobal has the tunnels. Both forts are amazing. If you like to walk, you can get to Morro from the Cruise ship area by following the paved pathway along the harbour...you go by Roots Fountain, past the Old City Gate, and around the bottom of Castillo San Felipe del Morrow....beautiful views of the harbour and up to the Fort. Great walk and no more than two kilometers...you can take a taxi back. Really nice walk. Have fun!!!!
