From Toulouse train station you travel in 1 hour to Montréjeau-Gourdan-Polignan, close to the Pyrenees. From here you can travel to Arties in about 2 hours, by bus and taxi via Bagnères de Luchon, or by taxi directly to Arties in just over 1 hour.
From Barcelona Nord bus station there are at least 4 direct buses a day to Vielha between 6.26am and 4.30pm (on Saturdays and Sundays the latter leaves at 4pm; on weekdays there is a later bus departure at 4.30pm). Check times and buy tickets in advance on www.alsa.es , especially during the high season.
Once in Vielha, you can continue by bus to Arties between mid-June and the end of September, if you have taken the 6.25am or 9am bus from Barcelona, as the other buses arrive late; long after the last bus leaves Vielha at 6.45 pm in the direction of Arties. But a taxi can't cost you a lot of money, as it's only a 7km drive between Vielha and Arties.
