if you remember way back 2004, Amazing Race (US Version) Season 5 had its second to the last stop in the Philippines and the roadblock on climbing the towering karst of El Nido was considered one of the most challenging. i included two clips from the episode below.
“despite the difficult challenges, we enjoyed every place we went. specially Palawan” Season 4 winner Chip and Kim claimed after an interview of their experience of the race. the platform used in that roadblock is now set at Miniloc's big lagoon relocated from Lagen island.

the scrapped walls in the channel to the big lagoon seemed to have been trimmed intentionally. flat downwards touching the shallow waters on its inlet. as we cruised through, water got deeper.
this huge lagoon could have been a large dome and dangerous species is still believed to be dwelling in its deep dark waters. so not one from the group dared jump off. one round cruise inside this lagoon and had our way out on the same channel.
this stop of tour A is just a cruise-and-see as we've had a long time swimming in the small lagoon. both lagoons are actually located at the same side of the island with just a limestone wall separating it.
video clips from Amazing Race Season 5 (US Version) when they had the roadblock challenge in El Nido Palawan. thanks to cfs224 for uploading and saving the video.
