The user is asking about the PR 6.4 Levada Velha do Rabaçal hike in Madeira. Let me look this up using the find_hikes tool.The user asked about "PR 6.4 Levada Velha do Rabaçal".

I should be honest that PR 6.4 Levada Velha do Rabaçal is not in our official trail data. Let me do a web lookup to see if this trail exists or has been closed/decommissioned.The user is asking about PR 6.4 Levada Velha do Rabaçal. I got detailed information from the find_hikes tool and the web_lookup. Let me compile the key details about this trail. From the results, I can see: - PR 6.4 - Levada Velha do Rabaçal is NOT in the official IFCN trail list returned by find_hikes (which returned PR 6, PR 6.1, PR 6.2, PR 6.6, and PR 6.8 instead). But it IS listed on visitmadeira.com and the official Madeira government site. Key details from the web_lookup: - **Distance:** 5 km - **Duration:** 2 hours - **Start point:** Pico Gordo (ER 105) - **End point:** Casa do Rabaçal - **Max altitude:** 1190 m - **Min altitude:** 1038 m - **Status:** Open - **Access fee:** €4.50 for visitors over 12 years; exempt for visitors 12 and under - **Managing entity:** IFCN (implied as part of the Rabaçal area) Description: The route starts at the regional road (ER 105) at Pico Gordo, and to reach Levada Velha do Rabaçal you walk approximately 800 meters. At the levada, turning right continues the walk to Casa do Rabaçal. Turning left leads to the impressively long Túnel das Estrebarias (also called Furado Velho), built in 1855 - this was the first time abundant north coast waters crossed the island to reach the drier south coast. Notable: The Levada Velha do Rabaçal is currently only explored between its spring and the vicinity of Casa do Rabaçal, and the water was subsequently diverted to Levada Nova do Rabaçal (das 25 Fontes) - so along the route you may encounter the channel without its usual water presence. The route passes through Laurisilva forest, classified as UNESCO World Natural Heritage since 1999.

However, the web search confirms it IS an official trail listed on Visit Madeira and IFCN. This might mean the tool doesn't have it yet or it was outside the search radius. Regardless, I have authoritative info from the official sources (Visit Madeira, IFCN government page). Let me write a comprehensive answer in English (since the question was inEnglish).
