While Nicaraguans are generally accommodating toward people with mobility issues, and will gladly give you a hand getting around, the combination of cobbled streets, cracked sidewalks and stairs in pretty much every building can make life tough.
There are few regular services for disabled travelers and because of difficulties in finding suitable transport, it’s easiest to go through a tour company. Vapues Tours (www.vapues.com) is an experienced local operator, specializing in accessible travel.
There are very few wheelchair-accessible toilets and bathrooms in Nicaragua, so bringing toilet-seat extensions, and wall-mountable mobility aids are highly recommended.
